Training Reasoning Models to Generate Diverse Scientific Ideas

Manya Wadhwa, Pranav Narayanan Venkit, Hiroaki Hayashi +3

One of the first steps of a research pipeline is generating ideas. Large Language Models (LLMs) are increasingly used to automate this step, but most of this work optimizes the qua…

Prospective Hindsight: Self-Calibrating Reinforcement Learning via Prediction-Reality Gaps

Jiaxin Zhang, Xiangyu Peng, Qinglin Chen +3

Reinforcement learning for long-horizon agents relies on purely retrospective training signals: credit is assigned only after observing environmental consequences, leaving the agen…

Fork Where the Model Changes Its Mind: Belief-Shift Branching for Tree-Structured Reinforcement Learning

Bin Lei, Yu Li, Prafulla Kumar Choubey +7

Tree-structured rollouts give critic-free reinforcement learning with verifiable rewards (RLVR) step-level credit: fork a chain at an intermediate point, and sibling outcome differ…

On the Fragility of Self-Improving Agents: Variance, Task Order, and Underspecification

Qinyuan Ye, Yu Li, Yada Pruksachatkun +2

Memory-based self-improving agents--those that learn from an online stream of tasks and improve over time by maintaining a textual memory bank--have shown great promise in recent l…

Speculate with Memory: Lossless Acceleration for LLM Agents

Yu Li, Qinyuan Ye, Prafulla Kumar Choubey +2

Speculative execution accelerates LLM agents by using a smaller, cheaper model to predict and pre-launch the next step while the environment is idle. However, existing speculators…

Dont Stop Early: Scalable Enterprise Deep Research with Controlled Information Flow and Evidence-Aware Termination

Prafulla Kumar Choubey, Kung-Hsiang Huang, Pranav Narayanan Venkit +5

Enterprise deep research often fails to produce decision-ready reports due to uneven information coverage, context explosion, and premature stopping. We propose a scalable Enterpri…
