Understanding Reinforcement Learning for Model Training, and future directions with GRAPE

This paper provides a self-contained, from-scratch, exposition of key algorithms for instruction tuning of models: SFT, Rejection Sampling, REINFORCE, Trust Region Policy Optimization (TRPO), Proximal Policy Optimization (PPO), Group Relative Policy Optimization (GRPO), and Direct Preference Optimization (DPO). Explanations of these algorithms often assume prior knowledge, lack critical details, and/or are overly generalized and complex. Here, each method is discussed and developed step by step using simplified and explicit notation focused on LLMs, aiming to eliminate ambiguity and provide a clear and intuitive understanding of the concepts. By minimizing detours into the broader RL literature and connecting concepts to LLMs, we eliminate superfluous abstractions and reduce cognitive overhead. Following this exposition, we provide a literature review of new techniques and approaches beyond those detailed. Finally, new ideas for research and exploration in the form of GRAPE (Generalized Relative Advantage Policy Evolution) are presented.

최근 마스토돈에서 캐릭터 커뮤니티(자캐커뮤)를 운영하시려는 분들이 늘어나서, 플래닛에서도 자캐커뮤에 대한 가이드라인을 제정하기로 했어요.
혹시 플래닛에서 자캐커뮤를 운영하시려 한다면, 다음 권고사항을 잘 지켜주시면 좋을 것 같아요.

- 2차 수정 - 자캐커뮤 가이드라인은 typie.me/0NbDvE 에 정리했습니다! (기존 사이트가 운영이 종료되어 이동했습니다)

"DOGEの根本的な問題は無謀で愚かな政府機関の解体ではなく、「世界一の富豪がアメリカ合衆国連邦政府の独自の省庁を買収し、その中で無制限の権力を行使できるようになったこと」だと指摘。"

「DOGE」がいかにめちゃくちゃだったのかを200人以上の連邦政府職員が証言

アメリカのドナルド・トランプ大統領は2025年1月に大統領に就任すると、アメリカ政府の無駄をなくすことを目的として「政府効率化省(DOGE)」を設立しました。後に仲たがいすることとなるイーロン・マスク氏が率いたDOGEが政府機関にどのような打撃を与えたのかについて、200人以上の連邦政府職員が証言した内容をまとめた記事が話題となっています。

Someone should invent a way for computers to count. At the moment both GMail and GitHub have incorrect message counts in my inbox. Again.

This has happened many times. Given that computers make it possible for me to order toilet paper for delivery by 2pm and then send me hundreds of messages about toilet paper by 5pm, it seems odd to me that they can't count.

But hey, I guess it's hard to count how many things are in a list, especially when the list is empty.

Guide to BDS Boycott & Pressure Corporate Priority Targeting

Ending the complicity of states, corporations, and institutions in Israel’s ongoing, live-streamed genocide against 2.3 million Palestinians in Gaza is the most effective form of solidarity with the Palestinian struggle to end the genocide and dismantle Israel’s 76-year-old regime of settler-colonialism and apartheid.

Microsoft has ended its collaboration with Israeli military intelligence Unit 8200 after it was revealed the unit used Azure to store millions of Palestinian phone calls daily, including data used to identify Gaza airstrike targets.

Following the exposure by The Guardian, +972, and Local Call, Microsoft confirmed violations of its terms of service, stating it does not support mass civilian surveillance.

The decision follows employee and investor pressure and protests under the banner “No Azure for Apartheid,” marking the first known U.S. tech cut-off of military services to Israel since the Gaza war intensified.
