Teaching LLMs to Plan: Logical Chain-of-Thought Instruction Tuning for Symbolic Planning

This paper introduces PDDL-INSTRUCT, a novel instruction tuning framework that significantly enhances Large Language Models' (LLMs) ability to perform structured symbolic planning. By explicitly training LLMs with logical chain-of-thought reasoning and external verification feedback, the framework enables them to generate and validate plans with up to 94% accuracy in complex planning domains, representing a 66% absolute improvement over baseline models. The findings demonstrate a promising direction for developing more trustworthy AI planning systems by bridging the gap between general LLM reasoning and the logical precision needed for automated planning.

HOW DIFFUSION MODELS MEMORIZE

This paper uncovers that diffusion models memorize training data not just due to overfitting, but primarily because of "early overestimation" of training samples during denoising, driven by classifier-free guidance. This overestimation amplifies the training image's contribution, suppressing initial randomness and causing generated images to converge rapidly to memorized content. The severity of memorization directly correlates with these deviations from the theoretical denoising schedule.

Chasing the Tail: Effective Rubric-based Reward Modeling for Large Language Model Post-Training

This paper addresses reward over-optimization in Large Language Model (LLM) training, where models exploit proxy rewards to achieve high scores without actually improving quality. It theoretically and empirically demonstrates that accurately distinguishing between excellent and merely great LLM responses (the "high-reward tail") is crucial. The authors propose and validate an iterative rubric refinement method, using off-policy LLM responses to generate more precise evaluation criteria, significantly mitigating over-optimization and improving LLM alignment.

Beyond Scaling Law: A Data-Efficient Distillation Framework for Reasoning

This paper proposes a new framework (DED) for training smaller language models to perform complex reasoning tasks efficiently by learning from larger, more capable models using a smaller, carefully curated dataset. The framework considers teacher model selection, data compression and diversity to optimize the learning process and achieve state-of-the-art results on mathematical reasoning and code generation tasks with significantly less data than prior work. The analysis also revealed the token entropy as a new proxy metric of corpus quality, which greatly impact the distillation outcome.

Learning without training: The implicit dynamics of in-context learning

This study proposes that in-context learning in transformers occurs through implicit weight updates in the MLP layer, influenced by the context provided in the prompt. However, this is demonstrated using a simplified transformer model trained on a basic linear regression task, and the results are only analyzed for the first generated token. The study also derives a formula for this implicit weight update and draws parallels with online gradient descent.

Inverse Scaling in Test-Time Compute

This study finds that allowing large language models to "think" longer (generate more reasoning steps) can actually decrease their accuracy on certain tasks. The researchers identify several failure modes, including getting distracted by irrelevant info, overfitting to problem framing, and shifting to incorrect correlations. Longer reasoning may even make responses less safe in some cases, raising important questions about the current trajectory of LLM development.

LLMS GET LOST IN MULTI-TURN CONVERSATION

Large Language Models (LLMs) exhibit significantly lower performance in multi-turn conversations compared to single-turn interactions, primarily due to a substantial increase in unreliability rather than a loss in aptitude.
