今天的主题是：On the Emergence of Thinking in LLMs I: Searching for the Right Intuition

Summary

The provided research explores how large language models (LLMs) can be transformed into more capable reasoning agents, termed large reasoning models (LRMs), by enabling a "thinking" process during inference. It introduces Reinforcement Learning via Self-Play (RLSP), a post-training framework that encourages guided search in LLMs through supervised fine-tuning on reasoning demonstrations, an exploration reward for diverse behavior, and reinforcement learning with an outcome verifier. Empirical results in mathematical problem-solving show that RLSP enhances reasoning abilities and fosters emergent behaviors like backtracking and self-correction across different model architectures and sizes. The work posits that RLSP's approach to incentivize the generation of novel reasoning trajectories through self-play contributes to the improved computational power and problem-solving capabilities of LLMs.

该研究探讨了如何将大型语言模型（LLMs）转化为更具推理能力的智能体，即“大型推理模型”（LRMs），通过在推理过程中引入“思考”机制实现能力提升。作者提出了一种名为“自对弈强化学习”（RLSP）的后训练框架，旨在引导LLMs进行有目标的搜索。该框架结合了基于推理示例的有监督微调、用于鼓励多样化行为的探索奖励，以及配备结果验证器的强化学习。在数学问题求解任务中的实验证明，RLSP显著提升了模型的推理能力，并促发了如回溯、自我纠错等新兴行为，在不同模型架构和规模中均表现出良好适应性。该研究认为，RLSP通过自对弈激励生成新颖的推理路径，有效提升了LLMs的计算能力与问题解决能力。

今天的主题是：Is Noise Conditioning Necessary for Denoising Generative Models?

Summary

This research investigates the common belief that noise conditioning is essential for denoising generative models. The authors surprisingly found that many of these models can still function effectively, and sometimes even better, without explicitly providing the noise level. They provide a theoretical analysis explaining this robustness and introduce a noise-unconditional model that achieves competitive image generation results, suggesting that revisiting the necessity of noise conditioning could lead to new advancements in the field.

今天的主题是：MoBA: Mixture of Block Attention for Long-Context LLMs

Summary

The provided technical report introduces Mixture of Block Attention (MoBA), a novel method to improve the efficiency of long-context large language models. MoBA applies the Mixture of Experts principle to the attention mechanism, allowing the model to selectively focus on relevant blocks of information instead of the entire context.
