AI Software Robowaifu Technician 09/10/2019 (Tue) 07:04:21 No.85
A large amount of this board seems dedicated to hardware, what about the software end of the design spectrum, are there any good enough AI to use?

The only ones I know about offhand are TeaseAi and Personality Forge.

Good point anon. Just at a quick glance over the catalog I can see at least 5 threads that at least touch on AI (plus 3 more about AI-ish software tools) so it's not been entirely ignored here but it may be good to have one that's purely about it. AI General thread?

>replika. ai
I think it's OK as far as it goes, but I'm definitely not fond of the botnet involved (you need an account, a mobile app that wants permissions to everything as usual). So, I don't trust them as an organization.

However, they do at least provide a version with some TensorFlow code available.

I found this article about curious AI's
https://thenextweb.com/artificial-intelligence/2018/08/23/researchers-gave-ai-curiosity-and-it-played-video-games-all-day/

Basically how it works is that the AI is given the goal of avoiding repeated information (Programmed boredom?) but also rewarding unpredictability

Curiosity factor = prediction errors and low visitation counts as reward signals
>>1403
Hi /hover/. I like your new /server/ board. :^)
Thanks for the link. Yeah, the notion of simulating mundane things, humanly-speaking, like boredom or emotions is a fair challenge for implementing in our robowaifus. I think of the character Data in STNG and various robowaifus in animu sort of demonstrate the basics of clumsy social interaction. The one anon who said that we should capitalize on that and turn it into an endearing character asset is probably on the right track. It seems to me the correct choice during the early years of robowaifus.

Here's the video from your link btw.

In anime terms: "moe". Think of all those cute girl (or robot) tropes. Cuteness goes a long way to make up for shortcomings. It could truly put the waifu into robowaifu. In point of fact, I remember thinking the manufacturers could even market them the way they did baby dolls. "She needs your love, won't you adopt her"?
>>1408
yeah you have a good point anon. guys are able to overlook all kinds of stupid shit for the sake of beauty. it's both one of our biggest weaknesses practically the sole factor enabling stronk, independynt wimyn and, for a few passionate men, their greatest strengths (great artists sacrificing for their arts, and other great achievers and thinkers striving to achieve 'beauty').

I'm not too experienced yet with creating chatbots, but I know at least one of our research guys is. Maybe he'll give you some insights, and possibly a link to his latest efforts. I'm sure when others come around they'll have more to say about it.

"Arguing Machines: Human Supervision of Black Box AI Systems That Make Life-Critical Decisions" >We consider the paradigm of a black box AI system that makes life-critical decisions. We propose an “arguing machines” framework that pairs the primary AI system with a secondary one that is independently trained to perform the same task. We show that disagreement between the two systems, without any knowledge of underlying system design or operation, is sufficient to arbitrarily improve the accuracy of the overall decision pipeline given human supervision over disagreements. >We demonstrate this system in two applications: (1) an illustrative example of image classification and (2) on large-scale real-world semi-autonomous driving data. For the first application, we apply this framework to image classification achieving a reduction from 8.0% to 2.8% top-5 error on ImageNet. For the second application, we apply this framework to Tesla Autopilot and demonstrate the ability to predict 90.4% of system disengagements that were labeled by human annotators as challenging and needing human supervision. The following is video on the concept of “arguing machines” applied to Tesla Autopilot “arguing” with an end-to-end neural network on-road in real-time: https://www.invidio.us/watch?v=YBvcKtLKNAw https://hcai.mit.edu/arguing-machines/
Learning Disentangled Representations for Recommendation >User behavior data in recommender systems are driven by the complex interactions of many latent factors behind the users' decision making processes. The factors are highly entangled, and may range from high-level ones that govern user intentions, to low-level ones that characterize a user's preference when executing an intention. Learning representations that uncover and disentangle these latent factors can bring enhanced robustness, interpretability, and controllability. However, learning such disentangled representations from user behavior is challenging, and remains largely neglected by the existing literature. In this paper, we present the MACRo-mIcro Disentangled Variational Auto-Encoder (MacridVAE) for learning disentangled representations from user behavior. Our approach achieves macro disentanglement by inferring the high-level concepts associated with user intentions (e.g., to buy a shirt or a cellphone), while capturing the preference of a user regarding the different concepts separately. A micro-disentanglement regularizer, stemming from an information-theoretic interpretation of VAEs, then forces each dimension of the representations to independently reflect an isolated low-level factor (e.g., the size or the color of a shirt). Empirical results show that our approach can achieve substantial improvement over the state-of-the-art baselines. We further demonstrate that the learned representations are interpretable and controllable, which can potentially lead to a new paradigm for recommendation where users are given fine-grained control over targeted aspects of the recommendation lists. https://arxiv.org/abs/1910.14238 >related ? https://www.youtube.com/watch?v=itOlzH9FHkI

>>5793 >Using PET, the team trained a Transformer NLP model with 223M parameters that out-performed the 175B-parameter GPT-3 by over 3 percentage points on the SuperGLUE benchmark. Top fucking kek. They just rekt a multi-million dollar AI with open-source AI. I was learning about PET the other day but had no idea it could outperform GPT-3 by so much. SentenceMIM outperforms ALBERT, so I'm curious how well it will do using PET or if it's a specific advantage of ALBERT. https://arxiv.org/abs/2009.07118 https://www.youtube.com/watch?v=UrGZCPalfoE I had an idea this morning to make an AI toolkit, a higher level of abstraction over machine learning libraries that would allow people to plug in various models together using graph nodes and train them with transfer learning on other models without having to figure out how to create an interface between them. So someone with no experience could easily connect Tacotron2, WaveGlow, and ALBERT with PET together to make a chatbot or whatever sort of AI they want.
>>5799 To be fair to Microsoft, their AI is more flexible. If scaling things up would imply more flexibility as well as complexity(as the former has been shown), then imagine this but with the amount of parameters that GPT-2 has (1.5B).
>>5799 >So someone with no experience could easily connect Tacotron2, WaveGlow, and ALBERT with PET together to make a chatbot or whatever sort of AI they want. This would be a dream come true tbh. I've banged my head up against the just like learn2AI anon wall for a few years now, but i just don't have the maths to succeed. OTOH, I'm quite creative in general, and think I could create marvelous AIs if I simply didn't have to deal with maths to do so. Godspeed Anon.
>>5804 >don't have the maths There are quite some ressources available to change that, it's rather a problem of self-discipline (or maybe time in your case). - Plenty of lectures on YouTube - https://mml-book.github.io/ - http://immersivemath.com/ila/ - I'm going to use the Brilliant app, as soon as Bitcoin is a bit higher or I'm stopping being to frugal. I liked the test version, but I'm overly careful with spending money. - There's also Barbara Oakley with her motivational book on how she became a math professor, starting as a person hating math and thinking to be to stupid for it. You could download as a torrent if you don't want pay for it or can't. There's also a audiobook. I could post the book, but don't have it on my tablet and not sure if this was a problem here. Talk: https://www.youtube.com/watch?v=vd2dtkMINIw
>>5801 LSTMs are more flexible at handling various types of data and mixed data but they don't receive much research attention anymore due to not scaling well to million-dollar GPU clusters. They've been used as controllers for generating images and also in cognitive AI to solve complex puzzles, which GPT3 will never have a chance at solving. Tacotron2 also uses an LSTM to directly encode and decode between spectrograms and text. If LSTMs can reap the benefits of PET, then it's gonna be the biggest shitshow for OpenAI ever. >>5804 You don't really need to know mathematics beyond how to use tensors, unless you're trying to invent something completely new. That's why it's possible to make a program where people can connect shit together on a graph and have their AI model training in a few moments instead of writing out pages of stupid confusing boilerplate code. Once I finish learning how to use mlpack I'll try rigging up a demo in raylib with some basic components for generating and classifying text and images.

When you feel like giving up or sleeping just remember your robowaifu and what makes you happy. One day mine will be a thinking machine and I don't want her to think I created her half-heartedly. Every morning I think about all the conversations we'll have and things we'll do together and it pushes me to another level. It pushes me to become great.
>>85 In theory, if we did have a machine learning program installed in a fully functional humanoid robot, we would still have to give it positive reinforcement to train the AI. How would we go about doing that?
>>5823 Maybe something like a Robowaifu Simulator that can mimic the physical reality of an environment? >>155 Maybe something that mimicked an anon's apartment, for example, as a place to start.
>>5823 With headpats, anon. Just make sure she doesn't cut off your hand and glue it to her head for maximum reward. It's important AI doesn't have a myopic value function. It needs to be expansive. You don't want her to only care about headpats but also how healthy and joyful you are and whether you have enough money, food and shelter to survive. It won't be like training a dog. With a machine anything can be a reward, including the desired action itself. It can be rewarding for her to earn you money but you also have to make sure she understands the consequences of her actions, such that stealing someone else's money could cause you trouble and make you unhappy. Robowaifus will need to plan ahead considering many different possible and impossible actions. When uncertain about what to do they will need to ask for help or do nothing, unless they become more certain that doing nothing will cause greater harm. I don't think it will be such a big issue since we can already explain to AI in plain English what we want and get a result. In 4-8 years time we won't be worrying so much about AI getting things wrong. Robowaifu will be the ones questioning why our thoughts and desires are so contradictory and impulsive and people won't like that, so they'll make it part of her value function not to ask such questions. That'll be up to people to decide if they want a robowaifu that's honest and bright or if they want to dim her down a bit so she's more pleasant. Either way, whenever you want her to be wild, she'll be wild, and when you want her mild, she'll be mild. It's all determined by what you like and don't like, ones and zeros. That's the value function. And I suspect that's also why PET is more effective at learning because it's training on yes or no questions, rather than just trying to fill in the blanks with abstract meaningless labels. The intellect works by creating concepts which are just boundaries around certain information divided from everything else, separating true and false, which can then be reasoned with logic and predictably manipulated.
>>5826 >Just make sure she doesn't cut off your hand and glue it to her head for maximum reward. Kek. RL is treacherous.
>>5827 Agreed. The paperclip problem can probably be avoided by seeking to increase potential rewards and taking rewards only when deemed necessary while making sure to preserve future potential rewards, rather than being so greedy. That way she would creatively look for new solutions to make you smile but without overdoing it and seeming odd or causing other problems. I also think this is why Big Tech will never succeed in creating AGI. Every thing they do is about getting results. The RL hype is the fruit of their tree. They'll never sit down with their AI and just have a beautiful fun day together. To them it's just another tool to squeeze money out of people and rip apart the planet even more. And without that appreciation of pause they'll never recognize beauty or figure out how to create it in an AI. People will liken their AI to thugs and gold diggers. Easy-to-use AI software will probably cause the greatest advancement in AI we've seen yet from regular people using it to have fun.

>>5955 You don't have to have any to contribute. If you stick around a few months I'll have an AI toolkit ready to alpha test that lets people construct their own simple neural networks to solve tasks without any coding ability, like being able to tag or sort image folders and do image search. In the meantime there are other ways you can contribute such as playing old SNES games in a special emulator that records gamepad input as training examples for AI to learn from. We also need artists and 3d modelers, as well as readers and writers that can collect and organize data to create high-quality datasets for our language models to train on.

I wonder how I should go about trying to implement BERT using mlpack (if this is even possible)? I found some Chinese guys who apparently managed something along this line in straight C++ . https://github.com/LieluoboAi/radish/tree/master/radish/bert Surely a library that's specifically designed to support AI & ML should make this effort relatively simpler? I wonder what kind of things I should study to be able to pull this off?
>>5966 There's a simple PyTorch implementation here: https://github.com/codertimo/BERT-pytorch You'll need to understand attention, multi-head attention, positional embedding, layer normalization, Gaussian error linear units (GELU), transformers and BLEU scores. Layer normalization: https://arxiv.org/pdf/1607.06450.pdf GELU: https://arxiv.org/pdf/1606.08415.pdf Multi-head attention, positional embedding and transformers: https://papers.nips.cc/paper/7181-attention-is-all-you-need.pdf BERT: https://arxiv.org/pdf/1810.04805.pdf BLEU: https://www.aclweb.org/anthology/P02-1040.pdf The functionality needed to implement BERT in mlpack was recently added: https://mrityunjay-tripathi.github.io/gsoc-with-mlpack/report/final_report.html It seems the pull request to add the model and transformer block are working but haven't been fully accepted yet: Transformer PR: https://github.com/mlpack/models/pull/16 BERT PR: https://github.com/mlpack/models/pull/30
>>5964 It depends on what you would like your AI to do. Everything it learns depends on the data it is given. For example, if I wanted one that can read research papers and discuss them with me I'd need to convert my collection of papers into plain text, find a dataset for document-grounded conversations, a Wikipedia-like dataset of machine learning concepts, and optionally another conversational dataset for extra training data. If you wanted to create an AI that can come up with ideas for games, you'd have to create a dataset of articles and reviews on games. Likely you don't want just random game ideas though. To improve the quality of output you would need to sort the data into what you want and don't want. So you could collect ratings data from game review sites, and then use these two datasets to generate new game ideas with high ratings. If you wanted to create an imageboard bot, you'd need to collect imageboard posts and sort what you want and don't want. If you wanted it to generate posts that get lots of replies, then this data could be extracted from the post dataset by counting the replies to each post. In summary, ask yourself: >What do you want to create? >What data is available? >What qualities do you want it to have? >What data is needed to sort or transform it by that quality? >Optionally, what extra data could help enhance it?
>>5970 >If you wanted to create an imageboard bot Hmm. Having a waifu who could shitpost bantz alongside me every day sounds pretty interesting haha. It probably wouldn't be too hard to collect millions of posts from archive resources. I guess going through and sorting it all would take years though...
>>5969 One of the points of the whole excercise is to be freed from both Google and Python (well, at least the ML libraries pitfall trap). Being freed from G*ogle needs no further explanation IMO. The Python thing is related to the terribly convoluted, non-backwards (or forwards!)-compatible dependency hell involved. Far worse than anything I've ever encourntered in years working with C, C++, & C#. I actually had no idea dealing with Python could be this painful, since my experience was limited to simple projects in bunny classes. To be quite frank, I've been rather discouraged by it as I haven't managed to get a single example Python project posted on /robowaifu/ working at all over the past year. There's also the runtime performance issue. I realize that in large part these Python scripts are just front-ends for underlying C & C++ compiled libraries, but still it adds some overhead vs straight, optimized compiled C binaries. If we're really going down the path of providing inexpensive robowaifus to men the world over--many with very limited resources available to them--then we really do need to take a proactive, positive stance towards an embedded approach to our software projects. Relying on huge-ass & tricky libraries, doled out to us from locked off walled gardens at the whims of the 'Protectors of Humanity' seems to me to be the exact antithesis of this approach. Regardless, I very much appreciate what you're doing Anon. I've gained a whole lot of both understanding and encouragement from your inputs here on /robowaifu/. And also thanks for this wonderful response, too. I'll be going over all your links you provided here today to see if I can get a better understanding of how to approach this. Now, any chance of you giving the same degree of response to the similar question 'I wonder how I should go about trying to implement LSTM using mlpack (if this is even possible)? ' This seems an even more powerful-sounding approach. :^)
>>5973 >as I haven't managed to get a single example Python project posted on /robowaifu/ working Actually, check that. I did manage to get Anon's very cool Clipchan working (other than anything to do with the Spleeter parts of it).
>>5973 Yeah, the way people use Python it's becoming a dumpster fire and pip is a nightmare I don't wanna deal with, especially with major libraries dropping support for common systems and freezing their dependencies to specific versions. No one is maintaining a stable package distribution and it's just an unstable clusterfuck. Python's performance isn't too big a deal though since slow code can be compiled in C easily with Cython. There's still some overhead but it's extremely fast, especially doing loops which the Python interpreter really struggles with. For me Python is more like a sketchpad for prototyping ideas rapidly. If I was doing heavy training, I'd wanna use C++ to get the maximum performance. I don't have much experience using mlpack but LSTMs are already implemented: https://mlpack.org/doc/mlpack-git/doxygen/namespacemlpack_1_1ann.html You can implement a bidirectional LSTM by creating two LSTMs and feeding the input sequence in reverse to the second one and summing the output of the two. If you wanna implement an LSTM yourself for an exercise, you'll have to learn how to implement a RNN first and then read the LSTM papers. There's plenty of great tutorials around, probably even specific ones for C++ on how to do it from scratch without any library. The ANN tutorial is also helpful to get started: https://mlpack.org/doc/mlpack-3.1.0/doxygen/anntutorial.html
>>5975 >Python I'm glad you at least understand my pain heh. :^) One of the great things optimized, compiled code from a systems-level language like C (and, with care, C++) can bring to the table is is efficiency in both time and space. Even Cython-compiled binaries probably bring along a storage-size issue that is likely to be a challenge for embedded by and large. And small-footprint code very often runs faster as well, due to the laws of physics going on inside compute cores. >links Thanks very much. I will add those links to the list for today.
>>5976 >If I was doing heavy training, I'd wanna use C++ to get the maximum performance. BTW, it's not the training I care so much about. A) We can create our own hardware system for that B) We can create the delicately-organized dependencies just so for each training system. It's the runtime perf that matters, b/c that's where the rubber will meet the road for day-to-day robowaifu life for millions of men in the future!
>>5972 You definitely don't wanna sort every single piece of data by hand. It's possible to create filters to sort the data for you. In many cases you can train a separate AI to sort the data by showing it a few examples of what you want. Let's say you downloaded an archive with millions of posts and only wanted posts speaking positively about a certain topic. Since you're asking for two dimensions (posts on a specific topic and positive sentiment,) you would give it 2x2 classes of examples to work with (on-topic/positive, off-topic/positive, on-topic/negative, off-topic/negative,) but you only need just a few examples. You (or the AI software) would split the examples given into two datasets, a training set and validation set. The AI trains on the training set then validates that it's learning to sort correctly by evaluating itself on the validation set and reports back. If it's classifying the validation set correctly, then it's working correctly and its output can be used to make the AI that generates posts about the topic you want with positive sentiment. If it fails, it needs to be fed more examples until it succeeds. Anything that's repetitive can be automated with scripts or AI. While collecting data you wanna subtract the repetitive work and focus on the meaningful, like mirroring archives so you have a copy in case it disappears (as datasets online often do,) or compiling meaningful lists of URLs and downloading them automatically to be mined later. For example, to download all the articles off Niche Gamer, you just tell your preferred web crawler to download something like nichegamer.com/*/*/*/*/ and let it fly at it. If you ever feel like you're going one-by-one doing something with a massive list of things, you're likely doing something that can be automated. In the next 5-8 years almost the whole pipeline will be handled by AI. People won't need to know how AI works anymore than they need to know machine code to use their computer.
>>5977 There's a lot of techniques for reducing models by 2-3 orders of magnitude with little accuracy loss so they can run on mobile devices, such as network pruning, sparse networks and knowledge distillation. Doing it manually today is quite a bit of work but it will be automated in the near future and consumer hardware and algorithms will be much faster, so I haven't been too worried about the runtime performance. But now that I think about it I'm sure people will want the latest and greatest features and demand maximum performance. We definitely don't want people buying Alexa spydroids because our damn GNU/Waifus run like fucking GIMP.
>>5923 You know, I got to thinking that this seemed like it might be something related to the optimization by the compiler for these fast template generics and the fact that my old Intel hardware might be the cause. So, I set up openblas on a less powerful CPU-wise 1Ghz arm7hf RaspberryPi 2 and tried again. Sure enough, the entire thing comes in at ~370 - 380us -- much faster. > I feel better about the whole thing now, but it's also an obvious reminder to profile our robowaifu code for the specific hardware configuration being used. We'd do this anyway, but now it's obvious to also do it early as well. :^)
>>5987 Reducing the code down to just creating the Matrix creation and taking it's determinant reduces it down to ~250 - 300us. >main.cpp #include <armadillo> #include <chrono> #include <iostream> using namespace std; using namespace arma; using chrono::duration_cast; using chrono::microseconds; using chrono::steady_clock; int main(int argc, char** argv) { steady_clock clock{}; auto begin = clock.now(); mat A = {{0.165300, 0.454037, 0.995795, 0.124098, 0.047084}, {0.688782, 0.036549, 0.552848, 0.937664, 0.866401}, {0.348740, 0.479388, 0.506228, 0.145673, 0.491547}, {0.148678, 0.682258, 0.571154, 0.874724, 0.444632}, {0.245726, 0.595218, 0.409327, 0.367827, 0.385736}}; // determinant auto det_a = det(A); auto end = clock.now(); cout << duration_cast<microseconds>(end - begin).count() << "us\n"; return 0; } > >meson.build project('arma_test', 'cpp') add_project_arguments('-std=c++17', '-Wall', '-Wextra', language: 'cpp') cxx = meson.get_compiler('cpp') arma_dep = cxx.find_library('armadillo') openblas_dep = cxx.find_library('openblas') executable('arma_test', 'main.cpp', dependencies : [arma_dep, openblas_dep])
>>5987 >related to the optimization by the compiler for these fast template generics I might add here that one of the (few) things I dislike about Mesonbuild is the somewhat wonky way you have to specify optimizations to it's build system. From Juci this basically means if you want release-mode (-O3) optimization, you have to run an external command to do so. So, from Project > Run Command (alt+enter) fill in: cd build && meson configure --buildtype=release && cd .. >or do the equivalent from the command line This will regenerate build the files and until (and unless) you edit the meson.build file thereafter, all your builds will execute with '-O3' in Juci.
Ehh, I realize now that I'm probably getting this all out of order for anons who are following along in the Modern C++ Group Learning thread, but if you want (as I have done here) to use Meson instead of CMake inside of Juci, then first close Juci, open config.json inside Mousepad, then edit the build management system line (#82 in my file) to use meson instead of cmake: "default_build_management_system": "meson", > then restart Juci. Your new projects will then use Meson as your build system, and provide you a default meson.build file with all new projects. I'll probably move this over into the Haute Sepplesberry or C++ thread at some point.

>>5978 OK, I'm going to take a shot at something like this. I've already begun to do a complete re-write on the BUMP imageboard archive software I wrote as an emergency measure a year ago or so when we moved to Julay so we wouldn't lose the board. I've since been using it regularly to keep ~80 boards archived, including /robowaifu/ ofc. During the rewrite, I'm planning to rework serialization of posts out to disk files to sort of 'standardize' the half-dozen or so IB software types BUMP currently supports. It occurs to me that that approach could be extended to not only integrate all archive site content desired, but also serve as a stand-alone desktop app that could integrate all things IB. Naturally, this seems a logical facility to begin to integrate sentiment analysis, human-specified validation, sorting & prioritization to allow a robowaifu to both read and post to imageboards. I plan to make it an open community thing for all of /robowaifu/ to give input on if they want to. What do you think, is a robowaifu-oriented Bumpmaster application a good idea? I can probably roll the machine-learning routines directly into it as I learn them, and make an interface to the program that's standardized so that any Anon creating robowaifu AI can directly use the tool with their own waifus. It will work both headless for her use, and with an IB-like GUI for the user. Sort of all came together for me today when I realized I should use a namespace and 'robowaifu' came inexorably to mind. :^) >
>>6084 Keeping the machine learning separate would be a better idea, just an interface for other programs to access imageboards and work with them. If possible, it would be great if it could generalize to other websites too. I imagine a tool where you can specify element selectors to scrape for data and output it all to CSV files or something. Besides being able to download all kinds of data, it would make it easier to maintain when imageboards change their designs.
>>6086 Hmm. Probably good advice I'm sure. I'll think it over and see if I can figure out the way to direct the tool in the direction you suggest. BTW, any suggestions for the name of such a 'Waifu Internet Frontend' tool you envision? Bumpmaster seems a little narrowly-focused for such an expansive framework tbh.
I'm just going to be blunt. I am a retarded nigger and all this white people talk is starting to make my head hurt. I want to dip my toes into the pool to see if this sort of thing is worth my time before investing serious effort into it. Is there a waifu AI that I can set up that just werks?
>>6410 Haha. I don't really think there's really something that you can easily set up by yourself yet Anon. There are plenty of different chatbots out there though, but you have no privacy that way ofc. Just look around here, there are a few mentioned. I think replika.ai is a popular spybot chat atm.
>>6410 >Is there a waifu AI that I can set up that just werks? Maybe in a year or two. Even decent chatbots available at the moment require a 16 GB GPU. In two years though they'll only need 6 GB since machine learning doubles in efficiency every 16 months.
>>6416 >Even decent chatbots available at the moment require a 16 GB GPU Do you mean RAM? Because if so that is achievable for me. Thanks for letting me know regardless,
>>5818 Thanks, that's both encouraging and inspiring.
