Self-distilled policy optimization (SDPO) has become a popular paradigm for LLM post-training, where a model learns from its own predictions conditioned on privileged information. SDPO, however, is sensitive to how much each update step should be trusted: corrections from a self-teacher can be highly informative on some batches and misleading on others, and applying them uniformly with a fixed step size

Current AI-powered code assistance tools often struggle with poorly-defined problem statements that lack sufficient task context and requirements specification. Recent analysis of software engineering agents reveals that failures on such underspecified requests are highly correlated with longer trajectories involving either over-exploration or repeated attempts at applying the same fix without proper evolution

Long-horizon motion forecasting for multiple autonomous robots is challenging due to nonlinear agent interactions, compounding prediction errors, and continuous-time evolution of dynamics. Learned dynamics of such a system can be useful in various applications such as travel time prediction, prediction-guided planning and generative simulation of warehouse robots. In this work, we aim to develop an efficient

Tabular foundation models like TabPFN and TabICL achieve state-of-the-art performance through in-context learning, yet their architectures remain fundamentally opaque. We introduce KernelICL, a framework to enhance tabular foundation models with quantifiable sample-based inspectability. Building on the insight that in-context learning is akin to kernel regression, we make this mechanism explicit by replacing

Large language model (LLM) agents increasingly operate in streaming case-based reasoning (CBR) settings, where continuous improvement from past experience is crucial. Existing methods achieve this by storing past cases and retrieving similar ones as few-shot examples. This strategy fails near decision boundaries, where highly similar cases have conflicting outcomes and the discriminative factors are not
