Multi-view Sparse Laplacian Eigenmaps for nonlinear Spectral Feature Selection

no code implementations29 Jul 2023 Gaurav Srivastava, Mahesh Jangid

In this study, the authors propose Multi-view Sparse Laplacian Eigenmaps (MSLE) for feature selection, which effectively combines multiple views of the data, enforces sparsity constraints, and employs a scalable optimization algorithm to identify a subset of features that capture the fundamental data structure.

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.

Training and challenging models for text-guided fashion image retrieval

1 code implementation23 Apr 2022 Eric Dodds, Jack Culpepper, Gaurav Srivastava

Retrieving relevant images from a catalog based on a query image together with a modifying caption is a challenging multimodal task that can particularly benefit domains like apparel shopping, where fine details and subtle variations may be best expressed through natural language.

VisualTextRank: Unsupervised Graph-based Content Extraction for Automating Ad Text to Image Search

no code implementations5 Aug 2021 Shaunak Mishra, Mikhail Kuznetsov, Gaurav Srivastava, Maxim Sviridenko

Motivated by our observations in logged data on ad image search queries (given ad text), we formulate a keyword extraction problem, where a keyword extracted from the ad text (or its augmented version) serves as the ad image query.

Minimizing Area and Energy of Deep Learning Hardware Design Using Collective Low Precision and Structured Compression

no code implementations19 Apr 2018 Shihui Yin, Gaurav Srivastava, Shreyas K. Venkataramanaiah, Chaitali Chakrabarti, Visar Berisha, Jae-sun Seo

Deep learning algorithms have shown tremendous success in many recognition tasks; however, these algorithms typically include a deep neural network (DNN) structure and a large number of parameters, which makes it challenging to implement them on power/area-constrained embedded platforms.
