This is What Limits Current LLMs Edan Meyer 2024-05-04 | Recent advances in large language models (LLMs) have centered around more data, larger models, and larger context lengths. The ability of LLMs to learn in-context (i.e. in-context learning) makes longer context lengths extremely valuable. However, there are some problems with relying on just in-context learning to learn during inference.Social MediaYouTube - youtube.com/c/EdanMeyerTwitter - twitter.com/ejmejm1

Learning Forever, Backprop Is Insufficient Edan Meyer 2022-04-04 | #ai #mlContinual Learning, or Life-long learning, is becoming more popular in Machine Learning (ML). This new research paper talks about plasticity decay, and how normal backpropagation is insufficient for continual learning. The inherent non-stationary property in many problems, especially in Reinforcement Learning (RL), makes it difficult to learn. Continual Backpropagation (CBP) is proposed as a solution to this.Outline:0:00 - Overview2:00 - Paper Intro2:53 - Problems & Environments8:11 - Plasticity Decay Experiments11:45 - Continual Backprop Explained15:54 - Continual Backprop Experiments22:00 - Extra Interesting Experiments25:34 - SummaryPaper source: arxiv.org/abs/2108.06325Abstract:The Backprop algorithm for learning in neural networks utilizes two mechanisms: first, stochastic gradient descent and second, initialization with small random weights, where the latter is essential to the effectiveness of the former. We show that in continual learning setups, Backprop performs well initially, but over time its performance degrades. Stochastic gradient descent alone is insufficient to learn continually; the initial randomness enables only initial learning but not continual learning. To the best of our knowledge, ours is the first result showing this degradation in Backprop's ability to learn. To address this issue, we propose an algorithm that continually injects random features alongside gradient descent using a new generate-and-test process. We call this the Continual Backprop algorithm. We show that, unlike Backprop, Continual Backprop is able to continually adapt in both supervised and reinforcement learning problems. We expect that as continual learning becomes more common in future applications, a method like Continual Backprop will be essential where the advantages of random initialization are present throughout learning.
Is AI Research On the Wrong Path? Edan Meyer 2022-03-21 | Lots of research in Artificial Intelligence (AI) and Machine Learning (ML) in the past few years has focused on supervised learning, and more recently there has been a trend of constructing massive models and focusing on scaling (e.g. GPT-3, Gopher, AlphaCode). These aren't the only two areas of work, but is it perhaps a mistake to focus on these approaches in ML research? Is something like Reinforcement Learning (RL) more promising? I'm not sure, but these are some opinions I've heard from others.Physics simulation paper: arxiv.org/abs/2002.09405Face image generation paper: arxiv.org/pdf/1903.06048.pdfSource of other AI-gen images used (DALL-E): arxiv.org/abs/2102.12092

AI Doesn’t Move Like Humans - Here’s Why Edan Meyer 2022-01-04 | Options in Reinforcement Learning are a type of temporal abstraction of actions. The RL options framework takes into account the hierarchical nature of actions we see in real life. They allow AI / RL agents to better explore and achieve better results. This has been demonstrated in RL for robotics and for games. This is a very interesting area of Machine Learning that I highly recommend looking more into!Original options paper: https://people.cs.umass.edu/~barto/courses/cs687/Sutton-Precup-Singh-AIJ99.pdfExploration visualization reference: openreview.net/pdf?id=SkeIyaVtwB
Generating Photorealistic Images With OpenAI GLIDE Edan Meyer 2021-12-27 | GLIDE is OpenAI's new Computer Vision (CV) model that performs better than DALLE. I show you how to generate images with GLIDE in this video. The images it generates are very high quality, some are nearly photorealistic. You can also make AI generated art with the model just by changing the prompt! The model is 3 billion parameters, though the public model is only 300 million parameters.Paper: arxiv.org/abs/2112.10741GitHub: github.com/openai/glide-text2imColab Notebook: colab.research.google.com/github/woctezuma/glide-text2im-colab/blob/main/text2im.ipynb
Gopher Explained: 280 BILLION Parameter Model Beats GPT-3 Edan Meyer 2021-12-12 | Gopher is DeepMind's new large language model. With 280 billion parameters, it's larger than GPT-3. It gets state-of-the-art (SOTA) results in around 100 tasks. The best part of the Gopher paper is the wide and deep analysis on what scales with model size, performance on many tasks like language modeling, Q&A, logic tasks, and also a look into the ethics of large language models. I think the Gopher paper is a great example of what scaling research in Machine Learning should be about.Gopher Blog Post: deepmind.com/blog/article/language-modelling-at-scaleGopher Paper: storage.googleapis.com/deepmind-media/research/language-research/Training%20Gopher.pdfResource on Transformers: lilianweng.github.io/lil-log/2018/06/24/attention-attention.html#full-architecture

A New Theory For How The Brain Learns Edan Meyer 2021-09-22 | How the brain learns has long been a mystery that we have slowly uncovering bit by bit. Plasticity clearly plays a large rule in the process, but it is unclear exactly how it is used. This paper talk about how burst of spike / firings in neurons can send feedback signals to perform multiplexing and solve to credit assignment problem. It is quite an interesting theory!Burst-Dependent Synaptic Plasticity Can Coordinate Learning in Hierarchical Circuits Paper: nature.com/articles/s41593-021-00857-x

AI Assistants Are Actually Stupid Edan Meyer 2021-08-21 | Learn how virtual assistant like Alexa and Google Assistant work. AI assistants have gained a lot of popularity, so I thought I'd talk about how they work. Machine learning virtual assistants are becoming the norm, but there are still many issues with current virtual assistants.Note that I changed/left out some details of how these assistants work to make sure I don't violate NDA. The general concepts are accurate though.Intent Detection SOTA: paperswithcode.com/task/intent-detectionSlot Filling SOTA: paperswithcode.com/task/slot-filling
Computers Have Already Surpassed The Human Brain Edan Meyer 2021-07-24 | Computers and AI hardware may already be faster than the human brain. Though not easy to compare the two, there are actually many ways we can attempt to calculate whether the brain or AI performs more computations. Many people scoff at the human brain vs computer comparison, but there is some good work behind it and it is quite interesting!Source: openphilanthropy.org/brain-computation-reportCheck out the above more a much deeper dive into the details of the brain vs. computer argument.
AI That Codes vs. X-Google Programmer Edan Meyer 2021-07-17 | GitHub Copilot is an AI that can code, released in collaboration between GitHub and OpenAI. This video hopes to answer the question of whether an AI programmer or a Google programmer is better. Even though it can't get everything, Copilot is impressive. Is it a step towards the AI singularity? Or is it a step towards self-programming AI (AI that codes itself). It's impressive, but certainly not taking any jobs away from any programmers yet.GitHub Copilot: copilot.github.comTimestamps:0:00 Challenge Explanation0:54 Problem #13:44 Problem #29:08 Problem #312:33 Problem #416:53 Demonstrations & Afterthoughts
Self-Supervised RL - Learning Without Data [Zero to Paper] Edan Meyer 2021-07-07 | Inverse Reinforcement Learning with Natural Language Goals (LangGoal IRL) offers a way to do sample-efficient IRL and a way to generalize using self-supervised learning.

TRILLION Parameter Models Are Here Edan Meyer 2021-06-16 | Training a large model with Machine Learning used to be strictly limited by GPU memory, but now with Microsoft's new paper, ZeRO-Infinity, training much larger ML models is possible. ZeRO-Infinity allows training models with trillions of parameters with a modest amount of GPUs and finetuning many billion parameter models with just one GPU. This is a great advancement for anyone who wants to work with big models like GPT-2 and the like!

Bad ML Results? Try This Edan Meyer 2021-06-09 | After getting bad ML results, how to improve ML results is a common question. To get better ML results there are a number of points you can focus on. Improving your model is the obvious one, but there are also many other way to improve ML results (e.g. accuracy, recall, precision, f1 score). Methods include getting more data to assembling. There is no easy answer, but this video will hopefully give you somewhat of an idea of how to get starting with optimizing your Machine Learning approach.
