Improving Instruction Following in Language Models through Proxy-Based Uncertainty Estimation

ICML 2024poster

Assessing response quality to instructions in language models is vital but challenging due to the complexity of human language across different contexts. This complexity often results in ambiguous or inconsistent interpretations, making accurate assessment difficult. To address this issue, we propos…

Certifiably Robust Policy Learning against Adversarial Multi-Agent Communication

ICLR 2023poster

Communication is important in many multi-agent reinforcement learning (MARL) problems for agents to share information and make good decisions. However, when deploying trained communicative agents in a real-world application where noise and potential attackers exist, the safety of communication-based…

Optimal Admission Control for Multiclass Queues with Time-Varying Arrival Rates via State Abstraction

AAAI 2022technical

We consider a novel queuing problem where the decision-maker must choose to accept or reject randomly arriving tasks into a no buffer queue which are processed by N identical servers. Each task has a price, which is a positive real number, and a class. Each class of task has a different price distri…

Non-Parametric Stochastic Sequential Assignment With Random Arrival Times

IJCAI 2021poster

We consider a problem wherein jobs arrive at random times and assume random values. Upon each job arrival, the decision-maker must decide immediately whether or not to accept the job and gain the value on offer as a reward, with the constraint that they may only accept at most n jobs over some refer…
