Methods to evaluate Large Language Model (LLM) responses and detect inconsistencies, also known as hallucinations, with respect to the provided knowledge, are becoming increasingly important for LLM applications. Current metrics fall short in their ability to provide explainable decisions, systematically check all pieces of information in the response, and are often too computationally expensive to be used

We consider a local planner that utilizes model predictive control to locally deviate from a prescribed global path in response to dynamic environments, taking into account the system dynamics. To ensure the consistency between the local and global paths, we introduce the concept of locally homotopic paths for paths with different origins and destinations. We then formulate a hard constraint to ensure that

We study the problem of differentially private (DP) fine-tuning of large pre-trained models — a recent privacy-preserving approach suitable for solving downstream tasks with sensitive data. Existing work has demonstrated that high accuracy is possible under strong privacy constraint, yet requires significant computational overhead or modifications to the network architecture. We propose differentially private

Generative AI (GenAI) models have demonstrated remarkable capabilities in a wide variety of medical tasks. However, as these models are trained using generalist datasets with very limited human oversight, they can learn uses of medical products that have not been adequately evaluated for safety and efficacy, nor approved by regulatory agencies. Given the scale at which GenAI may reach users, unvetted recommendations

Effective question-intent understanding plays an important role in enhancing the performance of Question-Answering (QA) and Search systems. Previous research in open-domain QA has highlighted the value of intent taxonomies in comprehending data and facilitating answer generation and evaluation. However, existing taxonomies have limitations for specific domains. We’re interested in question intent for e-commerce
