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.

Is it an i or an l: Test-time Adaptation of Text Line Recognition Models

no code implementations29 Aug 2023 Debapriya Tula, Sujoy Paul, Gagan Madan, Peter Garst, Reeve Ingle, Gaurav Aggarwal

While text line recognition models are generally trained on large corpora of real and synthetic data, such models can still make frequent mistakes if the handwriting is inscrutable or the image acquisition process adds corruptions, such as noise, blur, compression, etc.

Sample-Efficient Personalization: Modeling User Parameters as Low Rank Plus Sparse Components

no code implementations7 Oct 2022 Soumyabrata Pal, Prateek Varshney, Prateek Jain, Abhradeep Guha Thakurta, Gagan Madan, Gaurav Aggarwal, Pradeep Shenoy, Gaurav Srivastava

We then study the framework in the linear setting, where the problem reduces to that of estimating the sum of a rank-$r$ and a $k$-column sparse matrix using a small number of linear measurements.

Node-Level Differentially Private Graph Neural Networks

1 code implementation23 Nov 2021 Ameya Daigavane, Gagan Madan, Aditya Sinha, Abhradeep Guha Thakurta, Gaurav Aggarwal, Prateek Jain

Graph Neural Networks (GNNs) are a popular technique for modelling graph-structured data and computing node-level representations via aggregation of information from the neighborhood of each node.

Block-Value Symmetries in Probabilistic Graphical Models

1 code implementation2 Jul 2018 Gagan Madan, Ankit Anand, Mausam, Parag Singla

These orbits are represented compactly using permutations over variables, and variable-value (VV) pairs, but they can miss several state symmetries in a domain.

A Survey of Distant Supervision Methods using PGMs

no code implementations10 May 2017 Gagan Madan

Relation Extraction refers to the task of populating a database with tuples of the form $r(e_1, e_2)$, where $r$ is a relation and $e_1$, $e_2$ are entities.

Topic Modeling Using Distributed Word Embeddings

no code implementations15 Mar 2016 Ramandeep S Randhawa, Parag Jain, Gagan Madan

We propose a new algorithm for topic modeling, Vec2Topic, that identifies the main topics in a corpus using semantic information captured via high-dimensional distributed word embeddings.
