rl-for-llms.md Reinforcement Learning for Language Models Yoav Goldberg, April 2023. Why RL? With the release of the ChatGPT model and followup large language models (LLMs), there was a lot of discussion of the importance of "RLHF training", that is, "reinforcement learning from human feedback". I was puzzled for a while as to why RL (Reinforcement Learning) is better than learning from demonstrat

Illustrating Reinforcement Learning from Human Feedback (RLHF) This article has been translated to Chinese 简体中文 and Vietnamese đọc tiếng việt. Language models have shown impressive capabilities in the past few years by generating diverse and compelling text from human input prompts. However, what makes a "good" text is inherently hard to define as it is subjective and context dependent. There are
navigation Pwnagotchi: Deep Reinforcement Learning for WiFi pwning! Pwnagotchi is an A2C-based “AI” powered by bettercap and running on a Raspberry Pi Zero W that learns from its surrounding WiFi environment in order to maximize the crackable WPA key material it captures (either through passive sniffing or by performing deauthentication and association attacks). This material is collected on disk
Infrastructure for Contextual Bandits and Reinforcement Learning — theme of the ML Platform meetup hosted at Netflix, Los Gatos on Sep 12, 2019. Contextual and Multi-armed Bandits enable faster and adaptive alternatives to traditional A/B Testing. They enable rapid learning and better decision-making for product rollouts. Broadly speaking, these approaches can be seen as a stepping stone to full-o
Build your own video game bots, using classic and cutting-edge algorithms.
Large language models (LLMs) have been increasingly used to interact with external environments (e.g., games, compilers, APIs) as goal-driven agents. However, it remains challenging for these language agents to quickly and efficiently learn from trial-and-error as traditional reinforcement learning methods require extensive training samples and expensive model fine-tuning. We propose Reflexion, a
AWS Machine Learning Blog Training a reinforcement learning Agent with Unity and Amazon SageMaker RL Unity is one of the most popular game engines that has been adopted not only for video game development but also by industries such as film and automotive. Unity offers tools to create virtual simulated environments with customizable physics, landscapes, and characters. The Unity Machine Learning A
RLHF(Reinforcement Learning from Human Feedback:人間のフィードバックからの強化学習)とは?:AI・機械学習の用語辞典 用語「RLHF」について説明。人間のフィードバックを使ってAIモデルを強化学習する手法を指す。OpenAIのChatGPT/InstructGPTでは、人間の価値基準に沿うように、言語モデルをRLHFでファインチューニング(微調整)している。 連載目次 用語解説 RLHF(Reinforcement Learning from Human Feedback)とは、「人間のフィードバックからの強化学習」という名前の通り、人間の価値基準に沿うように、人間のフィードバックを使ってAI(言語)モデルを強化学習で微調整(ファインチューニング)する手法である。なお強化学習とは、フィードバック(報酬や罰)に基づいて学習する方法のことだ。 R
OpenSpiel is a collection of environments and algorithms for research in general reinforcement learning and search/planning in games. OpenSpiel supports n-player (single- and multi- agent) zero-sum, cooperative and general-sum, one-shot and sequential, strictly turn-taking and simultaneous-move, perfect and imperfect information games, as well as traditional multiagent environments such as (partia
Finding good data and a good policy correspond to optimizing the lower bound, $F(\theta, q)$, with respect to the policy parameters and the experience. One common approach for maximizing the lower bound is to perform coordinate ascent on its arguments, alternating between optimizing the data distribution and the policy.1 Optimizing the Policy When optimizing the lower bound with respect to the pol

Several days ago, AlphaTensor was introduced by DeepMind on Nature. I think this is the third time that DeepMind’s Reinforcement Learning(RL) research hits Nature(AlphaGO, AlphaFold and AlphaTensor now). Although RL is powerful, it is more difficult to jump in because there are fewer resources or systematical resources on this topic. I guess the situation is better now, but this is how I felt when
Pwnagotchi is an A2C-based "AI" leveraging bettercap that learns from its surrounding WiFi environment to maximize the crackable WPA key material it captures (either passively, or by performing authentication and association attacks). This material is collected as PCAP files containing any form of handshake supported by hashcat, including PMKIDs, full and half WPA handshakes. Instead of merely pla
We propose Algorithm Distillation (AD), a method for distilling reinforcement learning (RL) algorithms into neural networks by modeling their training histories with a causal sequence model. Algorithm Distillation treats learning to reinforcement learn as an across-episode sequential prediction problem. A dataset of learning histories is generated by a source RL algorithm, and then a causal transf
The goal of this tutorial is to introduce you to Reinforce.jl library which is a Reinforcement Learning library written in Julia by Tom Breloff This is a library written mostly written by a single person and my theory is that Julia is what helps someone smart like Tom be this productive. So we’re gonna be doing some GitHub archaeology and try to figure out how everything in Reinforce.jl fits toget
