• RL in Name Only? Analyzing the Structural Assumptions in RL post-training for LLMs

  Published: 22 May, 2025 |  at  11:16 AM

  

  89.06 🤔

  本文通过理论和实验分析，揭示了当前RL（如GRPO）在LLM后训练中的MDP结构假设使其退化为过滤迭代监督微调，并指出响应长度增加源于奖励分配偏差，而非推理能力提升。

• Deep Learning for On-Street Parking Violation Prediction

  Published: 14 May, 2025 |  at  11:08 AM

  

  89.01 🤔

  This paper develops a Deep Learning model with a novel data smoothing technique to predict fine-grained on-street parking violation rates in Thessaloniki, Greece, using indirect features like weather and time, achieving improved accuracy (MAE of 0.146) over baseline methods.

• Large Language Models are Miscalibrated In-Context Learners

  Published: 25 May, 2025 |  at  11:24 AM

  

  88.84 🤔

  本文通过对大型语言模型在低资源场景下的校准问题进行深入分析，揭示上下文学习（ICL）未一致改善校准效果，并提出自集成方法显著提升校准性能（平均降低ECE 43%），同时维持或略提升任务性能。

• Nonparametric learning of covariate-based Markov jump processes using RKHS techniques

  Published: 8 May, 2025 |  at  12:18 AM

  

  88.71 🤔

  本文提出了一种基于再生核希尔伯特空间（RKHS）的非参数化方法，通过频率学和贝叶斯框架建模连续时间马尔可夫链（CTMC）中协变量驱动的非线性转移率，显著提升了个体化状态转移预测的准确性。

• Making Small Language Models Efficient Reasoners: Intervention, Supervision, Reinforcement

  Published: 17 May, 2025 |  at  11:04 AM

  

  88.64 🤔

  This paper introduces Temperature Scaling (TS) and Trace Length Control for Dynamic Reasoning (TLDR) to enhance token efficiency in small language models, achieving up to 50% reduction in response length with minimal accuracy loss across multiple reasoning benchmarks.
