Effective Backdoor Mitigation Depends on the Pre-training Objective

no code implementations25 Nov 2023 Sahil Verma, Gantavya Bhatt, Avi Schwarzschild, Soumye Singhal, Arnav Mohanty Das, Chirag Shah, John P Dickerson, Jeff Bilmes

In this work, we demonstrate that the efficacy of CleanCLIP in mitigating backdoors is highly dependent on the particular objective used during model pre-training.

Detecting Spurious Correlations via Robust Visual Concepts in Real and AI-Generated Image Classification

no code implementations3 Nov 2023 Preetam Prabhu Srikar Dammu, Chirag Shah

This undesirable property is the root cause of the manifestation of spurious correlations, which render models unreliable and prone to failure in the presence of distribution shifts.

Addressing Weak Decision Boundaries in Image Classification by Leveraging Web Search and Generative Models

no code implementations30 Oct 2023 Preetam Prabhu Srikar Dammu, Yunhe Feng, Chirag Shah

Our new method is able to (1) identify weak decision boundaries for such classes; (2) construct search queries for Google as well as text for generating images through DALL-E 2 and Stable Diffusion; and (3) show how these newly captured training samples could alleviate population bias issue.

Using Large Language Models to Generate, Validate, and Apply User Intent Taxonomies

no code implementations14 Sep 2023 Chirag Shah, Ryen W. White, Reid Andersen, Georg Buscher, Scott Counts, Sarkar Snigdha Sarathi Das, Ali Montazer, Sathish Manivannan, Jennifer Neville, Xiaochuan Ni, Nagu Rangan, Tara Safavi, Siddharth Suri, Mengting Wan, Leijie Wang, Longqi Yang

However, using LLMs to generate a user intent taxonomy and apply it for log analysis can be problematic for two main reasons: (1) such a taxonomy is not externally validated; and (2) there may be an undesirable feedback loop.

Conversational Search

Taking Search to Task

no code implementations12 Jan 2023 Chirag Shah, Ryen W. White, Paul Thomas, Bhaskar Mitra, Shawon Sarkar, Nicholas Belkin

For decades, scholars made a case for the role that a user's task plays in how and why that user engages in search and what a search system should do to assist.

RecXplainer: Amortized Attribute-based Personalized Explanations for Recommender Systems

no code implementations27 Nov 2022 Sahil Verma, Chirag Shah, John P. Dickerson, Anurag Beniwal, Narayanan Sadagopan, Arjun Seshadri

We evaluate RecXplainer on five real-world and large-scale recommendation datasets using five different kinds of recommender systems to demonstrate the efficacy of RecXplainer in capturing users' preferences over item attributes and using them to explain recommendations.
