Neural Conversational QA: Learning to Reason vs Exploiting Patterns

no code implementations EMNLP 2020 Nikhil Verma, Abhishek Sharma, Dhiraj Madan, Danish Contractor, Harshit Kumar, Sachindra Joshi

Neural Conversational QA tasks such as ShARC require systems to answer questions based on the contents of a given passage.

Towards Robust Real-Time Hardware-based Mobile Malware Detection using Multiple Instance Learning Formulation

no code implementations19 Apr 2024 Harshit Kumar, Sudarshan Sharma, Biswadeep Chakraborty, Saibal Mukhopadhyay

This study introduces RT-HMD, a Hardware-based Malware Detector (HMD) for mobile devices, that refines malware representation in segmented time-series through a Multiple Instance Learning (MIL) approach.

Learning Locally Interacting Discrete Dynamical Systems: Towards Data-Efficient and Scalable Prediction

no code implementations9 Apr 2024 Beomseok Kang, Harshit Kumar, Minah Lee, Biswadeep Chakraborty, Saibal Mukhopadhyay

Locally interacting dynamical systems, such as epidemic spread, rumor propagation through crowd, and forest fire, exhibit complex global dynamics originated from local, relatively simple, and often stochastic interactions between dynamic elements.

Studying the Impact of Stochasticity on the Evaluation of Deep Neural Networks for Forest-Fire Prediction

no code implementations23 Feb 2024 Harshit Kumar, Biswadeep Chakraborty, Beomseok Kang, Saibal Mukhopadhyay

We identify the Expected Calibration Error (ECE) as a robust metric that tests the proposed evaluation criteria, offering asymptotic guarantees of proper scoring rules and improved interpretability through calibration curves.

Learning Representations on Logs for AIOps

1 code implementation18 Aug 2023 Pranjal Gupta, Harshit Kumar, Debanjana Kar, Karan Bhukar, Pooja Aggarwal, Prateeti Mohapatra

Automated log analysis is a critical task in AIOps as it provides key insights for SREs to identify and address ongoing faults.

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.

Picking Pearl From Seabed: Extracting Artefacts from Noisy Issue Triaging Collaborative Conversations for Hybrid Cloud Services

no code implementations31 May 2021 Amar Prakash Azad, Supriyo Ghosh, Ajay Gupta, Harshit Kumar, Prateeti Mohapatra

We propose a combination of unsupervised and supervised model with minimum human intervention that leverages domain knowledge to predict artefacts for a small amount of conversation data and use that for fine-tuning an already pretrained language model for artefact prediction on a large amount of conversation data.

A Practical Dialogue-Act-Driven Conversation Model for Multi-Turn Response Selection

no code implementations IJCNLP 2019 Harshit Kumar, Arvind Agarwal, Sachindra Joshi

This paper proposes an end-to-end multi-task model for conversation modeling, which is optimized for two tasks, dialogue act prediction and response selection, with the latter being the task of interest.

Neural Conversational QA: Learning to Reason v.s. Exploiting Patterns

2 code implementations9 Sep 2019 Nikhil Verma, Abhishek Sharma, Dhiraj Madan, Danish Contractor, Harshit Kumar, Sachindra Joshi
