  • A Summary of Netflix's Research on Cosine Similarity Unreliability in Semantic Embeddings

    A Summary of Netflix's Research on Cosine Similarity Unreliability in Semantic Embeddings
    2024/12/23
    This episode analyzes the research paper titled "Is Cosine-Similarity of Embeddings Really About Similarity?" by Harald Steck, Chaitanya Ekanadham, and Nathan Kallus from Netflix Inc. and Cornell University, published on March 11, 2024. It examines the effectiveness of cosine similarity as a metric for assessing semantic similarity in high-dimensional embeddings, revealing limitations that arise from different regularization methods used in embedding models. The discussion explores how these regularization schemes can lead to unreliable or arbitrary similarity scores, challenging the conventional reliance on cosine similarity in applications such as language models and recommender systems. Additionally, the episode reviews the authors' proposed solutions, including training models with cosine similarity in mind and alternative data projection techniques, and presents their experimental findings that underscore the importance of critically evaluating similarity measures in machine learning practices.

  • Key insights from Salesforce Research: Enhancing LLMs with Offline Reinforcement Learning

    Key insights from Salesforce Research: Enhancing LLMs with Offline Reinforcement Learning
    2024/12/23
    This episode analyzes the research paper "Offline Reinforcement Learning for LLM Multi-Step Reasoning" authored by Huaijie Wang, Shibo Hao, Hanze Dong, Shenao Zhang, Yilin Bao, Ziran Yang, and Yi Wu, affiliated with UC San Diego, Tsinghua University, Salesforce Research, and Northwestern University. The discussion explores the limitations of traditional methods like Direct Preference Optimization in enhancing large language models (LLMs) for complex multi-step reasoning tasks. It introduces the novel Offline REasoning Optimization (OREO) approach, which leverages offline reinforcement learning to improve the reasoning capabilities of LLMs without the need for extensive paired preference data. The episode delves into OREO's methodology, including its use of maximum entropy reinforcement learning and the soft Bellman Equation, and presents the significant performance improvements achieved on benchmarks such as GSM8K, MATH, and ALFWorld. Additionally, it highlights the broader implications of OREO for the future development of more reliable and efficient language models in various applications.
