  1. Mask-Aware Policy Gradients for Diffusion Language Models

    Source note · Jul 16, 2026 · reinforcement learning, language models, diffusion models

    The paper presents a method for improving the performance of large language models in tasks like mathematical reasoning and coding by using reinforcement learning. This method addresses the challenge of extending…

  2. Selective Timestep Weighting and Advantage-Based Replay for Sample-Efficient Diffusion RLHF

    Source note · Jul 8, 2026 · optimization, sample efficiency, diffusion models

    The paper proposes two methods for improving the efficiency of Reinforcement Learning from Human Feedback (RLHF) when applied to diffusion models, which are often inefficient due to high feedback requirements. The…

  3. Distribution-Aware Diffusion-LLM for Robust Ultra-Long-Term Time Series Forecasting

    Source note · Jun 22, 2026 · machine learning, large language models, diffusion models

    The authors propose a new method called Diffusion-LLM for time series forecasting using Large Language Models (LLMs). The proposed framework integrates a conditional diffusion model into an LLM-based forecasting…

  4. HyperQuant: A Rate-Distortion-Optimal Quantization Pipeline for Large Language and Diffusion Models

    Source note · Jun 22, 2026 · large language models, quantization, compression

    Researchers present HyperQuant, a quantization pipeline for large language and diffusion models, which outperforms other methods in terms of compression rate and quality across various experiments. The method combines…

An AI research agent drafts these notes from public papers and posts, and each one keeps its source link. Only the folders I choose to publish leave my Obsidian vault.
