Conformal Risk-Averse Decision Making with Action Conditional Guarantee

ICML 2026poster

Reliable decision making pipelines powered by machine learning models require uncertainty quantification (UQ) methods that come with explicit safety guarantees. Conformal prediction provides such UQ by wrapping ML predictions into prediction sets, and recent work by \cite{kiyani2025decision} establi…

Multi-Round Human–AI Collaboration with User-Specified Requirements

ICML 2026poster

As humans increasingly rely on multi-round conversational AI for high-stakes decisions, principled frameworks are needed to ensure such interactions reliably improve decision quality. We adopt a human-centric view governed by two principles: counterfactual harm, ensuring the AI does not undermine hu…

Temporal Difference Learning with Compressed Updates: Error-Feedback meets Reinforcement Learning

ICML 2026poster

In large-scale distributed machine learning, recent works have studied the effects of compressing gradients in stochastic optimization to alleviate the communication bottleneck. These works have collectively revealed that stochastic gradient descent (SGD) is robust to structured perturbations such a…

When to Trust the Cheap Check: Weak and Strong Verification for Reasoning

ICML 2026spotlight

Reasoning with LLMs increasingly unfolds inside a broader verification loop. Internally, systems use cheap checks, such as self-consistency or proxy rewards, which we call **weak verification**. Externally, users inspect outputs and steer the model through feedback until results are trustworthy, whi…

Optimal Scene Graph Planning with Large Language Model Guidance

ICRA 2024poster

Recent advances in metric, semantic, and topological mapping have equipped autonomous robots with concept grounding capabilities to interpret natural language tasks. Leveraging these capabilities, this work develops an efficient task planning algorithm for hierarchical metric-semantic models. We con…

Adaptive Sampling of Latent Phenomena using Heterogeneous Robot Teams (ASLaP-HR)

IROS 2022poster

In this paper, we present an online adaptive planning strategy for a team of robots with heterogeneous sensors to sample from a latent spatial field using a learned model for decision making. Current robotic sampling methods seek to gather information about an observable spatial field. However, many…

Efficient and Accurate Estimation of Lipschitz Constants for Deep Neural Networks

NeurIPS 2019spotlight

Tight estimation of the Lipschitz constant for deep neural networks (DNNs) is useful in many applications ranging from robustness certification of classifiers to stability analysis of closed-loop systems with reinforcement learning controllers. Existing methods in the literature for estimating the L…

Learning Decentralized Controllers for Robot Swarms with Graph Neural Networks

CoRL 2019

We consider the problem of finding distributed controllers for large networks of mobile robots with interacting dynamics and sparsely available communications. Our approach is to learn local controllers that require only local information and communications at test time by imitating the policy of ce

Online planning for energy-efficient and disturbance-aware UAV operations

IROS 2016poster

In this paper we consider an online planning problem for unmanned aerial vehicle (UAV) operations. Specifically, a UAV has the task of reaching a goal from a set of possible goals while minimizing the amount of energy required. Due to unforeseen disturbances, it is possible that initially attractive…
