Submodlib: A Submodular Optimization Library

1 code implementation22 Feb 2022 Vishal Kaushal, Ganesh Ramakrishnan, Rishabh Iyer

A recent work has also leveraged submodular functions to propose submodular information measures which have been found to be very useful in solving the problems of guided subset selection and guided summarization.

Submodular Mutual Information for Targeted Data Subset Selection

no code implementations30 Apr 2021 Suraj Kothawade, Vishal Kaushal, Ganesh Ramakrishnan, Jeff Bilmes, Rishabh Iyer

With the rapid growth of data, it is becoming increasingly difficult to train or improve deep learning models with the right subset of data.

PRISM: A Rich Class of Parameterized Submodular Information Measures for Guided Subset Selection

1 code implementation27 Feb 2021 Suraj Kothawade, Vishal Kaushal, Ganesh Ramakrishnan, Jeff Bilmes, Rishabh Iyer

Examples of such problems include: i)targeted learning, where the goal is to find subsets with rare classes or rare attributes on which the model is underperforming, and ii)guided summarization, where data (e. g., image collection, text, document or video) is summarized for quicker human consumption with specific additional user intent.

Realistic Video Summarization through VISIOCITY: A New Benchmark and Evaluation Framework

no code implementations29 Jul 2020 Vishal Kaushal, Suraj Kothawade, Rishabh Iyer, Ganesh Ramakrishnan

Thirdly, we demonstrate that in the presence of multiple ground truth summaries (due to the highly subjective nature of the task), learning from a single combined ground truth summary using a single loss function is not a good idea.

Vis-DSS: An Open-Source toolkit for Visual Data Selection and Summarization

1 code implementation24 Sep 2018 Rishabh Iyer, Pratik Dubal, Kunal Dargan, Suraj Kothawade, Rohan Mahadev, Vishal Kaushal

With increasing amounts of visual data being created in the form of videos and images, visual data selection and summarization are becoming ever increasing problems.

Learning From Less Data: Diversified Subset Selection and Active Learning in Image Classification Tasks

no code implementations28 May 2018 Vishal Kaushal, Anurag Sahoo, Khoshrav Doctor, Narasimha Raju, Suyash Shetty, Pankaj Singh, Rishabh Iyer, Ganesh Ramakrishnan

Supervised machine learning based state-of-the-art computer vision techniques are in general data hungry and pose the challenges of not having adequate computing resources and of high costs involved in human labeling efforts.

A Unified Multi-Faceted Video Summarization System

no code implementations4 Apr 2017 Anurag Sahoo, Vishal Kaushal, Khoshrav Doctor, Suyash Shetty, Rishabh Iyer, Ganesh Ramakrishnan

Most importantly, we also show that we can summarize hours of video data in a few seconds, and our system allows the user to generate summaries of various lengths and types interactively on the fly.
