Analyzing the Efficacy of an LLM-Only Approach for Image-based Document Question Answering

no code implementations25 Sep 2023 Nidhi Hegde, Sujoy Paul, Gagan Madan, Gaurav Aggarwal

Recent document question answering models consist of two key components: the vision encoder, which captures layout and visual elements in images, and a Large Language Model (LLM) that helps contextualize questions to the image and supplements them with external world knowledge to generate accurate answers.

FineDeb: A Debiasing Framework for Language Models

1 code implementation5 Feb 2023 Akash Saravanan, Dhruv Mullick, Habibur Rahman, Nidhi Hegde

Our results show that FineDeb offers stronger debiasing in comparison to other methods which often result in models as biased as the original language model.

Long Term Fairness for Minority Groups via Performative Distributionally Robust Optimization

no code implementations12 Jul 2022 Liam Peet-Pare, Nidhi Hegde, Alona Fyshe

Fairness researchers in machine learning (ML) have coalesced around several fairness criteria which provide formal definitions of what it means for an ML model to be fair.

IITK at SemEval-2021 Task 10: Source-Free Unsupervised Domain Adaptation using Class Prototypes

no code implementations SEMEVAL 2021 Harshit Kumar, Jinang Shah, Nidhi Hegde, Priyanshu Gupta, Vaibhav Jindal, Ashutosh Modi

To tackle this issue of availability of annotated data, a lot of research has been done on unsupervised domain adaptation that tries to generate systems for an unlabelled target domain data, given labeled source domain data.

Multi Type Mean Field Reinforcement Learning

1 code implementation6 Feb 2020 Sriram Ganapathi Subramanian, Pascal Poupart, Matthew E. Taylor, Nidhi Hegde

We consider two different kinds of mean field environments: a) Games where agents belong to predefined types that are known a priori and b) Games where the type of each agent is unknown and therefore must be learned based on observations.

Adaptive Active Hypothesis Testing under Limited Information

no code implementations NeurIPS 2017 Fabio Cecchi, Nidhi Hegde

We consider the problem of active sequential hypothesis testing where a Bayesian decision maker must infer the true hypothesis from a set of hypotheses.

The Price of Privacy in Untrusted Recommendation Engines

no code implementations13 Jul 2012 Siddhartha Banerjee, Nidhi Hegde, Laurent Massoulié

In the information-rich regime, where each user rates at least a constant fraction of items, a spectral clustering approach is shown to achieve a sample-complexity lower bound derived from a simple information-theoretic argument based on Fano's inequality.
