Dissecting Bias in LLMs: A Mechanistic Interpretability Perspective

no code implementations5 Jun 2025 Bhavik Chandna, Zubair Bashir, Procheta Sen

Large Language Models (LLMs) are known to exhibit social, demographic, and gender biases, often as a consequence of the data on which they are trained.

A Counterfactual Explanation Framework for Retrieval Models

no code implementations1 Sep 2024 Bhavik Chandna, Procheta Sen

However, limited attention has been given to understanding why a particular document is not favored (e. g. not within top-K) with respect to a query and a retrieval model.

Adaptive Retrieval-Augmented Generation for Conversational Systems

no code implementations31 Jul 2024 Xi Wang, Procheta Sen, Ruizhe Li, Emine Yilmaz

Despite the success of integrating large language models into the development of conversational systems, many studies have shown the effectiveness of retrieving and augmenting external knowledge for informative responses.

Regularized Gradient Clipping Provably Trains Wide and Deep Neural Networks

1 code implementation12 Apr 2024 Matteo Tucat, Anirbit Mukherjee, Procheta Sen, Mingfei Sun, Omar Rivasplata

We present and analyze a novel regularized form of the gradient clipping algorithm, proving that it converges to global minima of the loss surface of deep neural networks under the squared loss, provided that the layers are of sufficient width.

Can Word Sense Distribution Detect Semantic Changes of Words?

1 code implementation16 Oct 2023 Xiaohang Tang, Yi Zhou, Taichi Aida, Procheta Sen, Danushka Bollegala

Given this relationship between WSD and SCD, we explore the possibility of predicting whether a target word has its meaning changed between two corpora collected at different time steps, by comparing the distributions of senses of that word in each corpora.

Lexical Entrainment for Conversational Systems

1 code implementation14 Oct 2023 Zhengxiang Shi, Procheta Sen, Aldo Lipani

To address this, we propose a new dataset, named MULTIWOZ-ENTR, and a measure for LE for conversational systems.

Response Generation

Automated Argument Generation from Legal Facts

no code implementations9 Oct 2023 Oscar Tuvey, Procheta Sen

The count of pending cases has shown an exponential rise across nations (e. g., with more than 10 million pending cases in India alone).

LIPEx-Locally Interpretable Probabilistic Explanations-To Look Beyond The True Class

no code implementations7 Oct 2023 Hongbo Zhu, Angelo Cangelosi, Procheta Sen, Anirbit Mukherjee

This data-efficiency is seen to manifest as LIPEx being able to compute its explanation matrix around 53% faster than all-class LIME, for classification experiments with text data.

Multi-Objective Few-shot Learning for Fair Classification

no code implementations5 Oct 2021 Ishani Mondal, Procheta Sen, Debasis Ganguly

In this paper, we propose a general framework for mitigating the disparities of the predicted classes with respect to secondary attributes within the data (e. g., race, gender etc.).

Towards Socially Responsible AI: Cognitive Bias-Aware Multi-Objective Learning

no code implementations14 May 2020 Procheta Sen, Debasis Ganguly

Human society had a long history of suffering from cognitive biases leading to social prejudices and mass injustice.

Word-Node2Vec: Improving Word Embedding with Document-Level Non-Local Word Co-occurrences

no code implementations NAACL 2019 Procheta Sen, Debasis Ganguly, Gareth Jones

However, this strong assumption may not capture the semantic association between words that co-occur frequently but non-locally within documents.
