All models are wrong, some are useful: Model Selection with Limited Labels

AISTATS 2025poster

We introduce MODEL SELECTOR, a framework for label-efficient selection of pretrained classifiers. Given a pool of unlabeled target data, MODEL SELECTOR samples a small subset of highly informative examples for labeling, in order to efficiently identify the best pretrained model for deployment on thi…

C-RAG: Certified Generation Risks for Retrieval-Augmented Language Models

ICML 2024poster

Despite the impressive capabilities of large language models (LLMs) across diverse applications, they still suffer from trustworthiness issues, such as hallucinations and misalignments. Retrieval-augmented language models (RAG) have been proposed to enhance the credibility of generations by groundin…

COLEP: Certifiably Robust Learning-Reasoning Conformal Prediction via Probabilistic Circuits

ICLR 2024poster

Conformal prediction has shown spurring performance in constructing statistically rigorous prediction sets for arbitrary black-box machine learning models, assuming the data is exchangeable. However, even small adversarial perturbations during the inference can violate the exchangeability assumption…

Repeated Random Sampling for Minimizing the Time-to-Accuracy of Learning

ICLR 2024poster

Methods for carefully selecting or generating a small set of training data to learn from, i.e., data pruning, coreset selection, and dataset distillation, have been shown to be effective in reducing the ever-increasing cost of training neural networks. Behind this success are rigorously designed, ye…

Knowledge Enhanced Machine Learning Pipeline against Diverse Adversarial Attacks

ICML 2021spotlight

Despite the great successes achieved by deep neural networks (DNNs), recent studies show that they are vulnerable against adversarial examples, which aim to mislead DNNs by adding small adversarial perturbations. Several defenses have been proposed against such attacks, while many of them have been…

Online Active Model Selection for Pre-trained Classifiers

AISTATS 2021poster

Given $k$ pre-trained classifiers and a stream of unlabeled data examples, how can we actively decide when to query a label so that we can distinguish the best model from the rest while making a small number of queries? Answering this question has a profound impact on a range of practical scenarios.…

Towards Efficient Data Valuation Based on the Shapley Value

AISTATS 2019poster

{\em “How much is my data worth?”} is an increasingly common question posed by organizations and individuals alike. An answer to this question could allow, for instance, fairly distributing profits among multiple data contributors and determining prospective compensation when data breaches happen. I…
