I currently serve as a Faculty Chair of Jay Chaudhry Software Innovation Centre at Indian Institute of Technology (BHU) Varanasi and also an associated faculty member in the Department of Computer Science and Engineering.

My PhD research deals with the quantum-inspired information retrieval framework with a focus on user-oriented IR, where I investigated how users' information needs can be ascertained during their search behaviour using Information Foraging Theory. My research spans across formal information retrieval (IR) models, in particular, the mathematical formalism(s) behind Quantum Theory; Quantum Probability, Hilbert space and their usage in the study of contextual information retrieval. Besides information retrieval, I am also interested in the synergy between machine learning/deep learning and quantum probabilistic frameworks, and their applications in finance and healthcare sector.

I began my studies in Computer Science at the Chhatrapati Shahu Ji Maharaj University (formerly Kanpur University) in India, culminating in a PhD in Quantum Information Retrieval under the supervision of Dr. Haiming Liu and Dr. Ingo Frommholz from University of Bedfordshire, where I was a Marie Skłodowska-Curie fellow within the QUARTZ ITN consortium. Following my PhD, I joined the department of Statistics as a Research Engineer within the School of Mathematics at University of Leeds, where I worked with Dr. Leonid Bogachev on rapid prototyping of statistical machine learning approaches focussed on Financial AI projects which spin-out as 4-XTRA Technologies Ltd. In April 2022, I moved to the University College London (UCL) as a Postdoctoral Research Fellow, where I worked with Prof. Alexey Zaikin and Dr. Oleg Blyuss on developing statistical machine learning and deep temporal vision models for risk stratification of Prostate cancer progression. From April 2023 onwards, I was a Postdoctoral Research Fellow at the University of Surrey, working on applied research at the intersection of Generative AI, Web 3.0, and Blockchain. Since November '24, I have transitioned to an honorary fellow.

Before graduate school, I was also a part of Google Summer of Code program and the Linux Foundation as an intern with Kubernetes, CNCF and Openstack team at the Open Mainframe Project.

Applications currently open (start date as soon as possible) for an AI research engineer internship at IIT-BHU: apply here through the interest form.

FakeClaim: A Multiple Platform-Driven Dataset for Identification of Fake News on 2023 Israel-Hamas War

Gautam Kishore Shahi, Amit Kumar Jaiswal, Thomas Mandl

In Proceedings of the 46th European Conference on Information Retrieval (ECIR) (IR4Good Track 2024)

We contribute the first publicly available dataset of factual claims from different platforms and fake YouTube videos on the 2023 Israel-Hamas war for automatic fake YouTube video classification. The FakeClaim data is collected from 60 fact-checking organizations in 30 languages and enriched with metadata from the fact-checking organizations curated by trained journalists specialized in fact-checking. Further, we classify fake videos within the subset of YouTube videos using textual information and user comments. ...

Lightweight Adaptation of Neural Language Models via Subspace Embedding

Amit Kumar Jaiswal, Haiming Liu

In Proceedings of the 32nd ACM International Conference on Information and Knowledge Management (CIKM 2023)

Traditional neural word embeddings are usually dependent on a richer diversity of vocabulary. However, the language models recline to cover major vocabularies via the word embedding parameters, in particular, for multilingual language models that generally cover a significant part of their overall learning parameters. In this work, we present a new compact embedding structure to reduce the memory footprint of the pre-trained language models with a sacrifice of up to 4\% absolute accuracy. The embeddings vectors reconstruction follows a set of subspace embeddings and an assignment procedure via the contextual relationship among tokens from pre-trained language models. ...

Towards Subject Agnostic Affective Emotion Recognition

Amit Kumar Jaiswal, Haiming Liu, Prayag Tiwari

In Proceedings of the 2nd MUWS Workshop at the 32nd ACM International Conference on Information and Knowledge Management (CIKM 2023)

This paper focuses on affective emotion recognition, aiming to perform in the subject-agnostic paradigm based on EEG signals. However, EEG signals manifest subject instability in subject-agnostic affective Brain-computer interfaces (aBCIs), which led to the problem of distributional shift. Furthermore, this problem is alleviated by approaches such as domain generalisation and domain adaptation. Typically, methods based on domain adaptation confer comparatively better results than the domain generalisation methods but demand more computational resources given new subjects. We propose a novel framework, meta-learning based augmented domain adaptation for subject-agnostic aBCIs. ...

A Model-Agnostic Framework for Recommendation via Interest-aware Item Embeddings

Amit Kumar Jaiswal, Yu Xiong

In Proceedings of the 17th ACM Conference on Recommender Systems (RecSys 2023) Late-Breaking Results

Item representation holds significant importance in recommendation systems, which encompasses domains such as news, retail, and videos. Retrieval and ranking models utilise item representation to capture the user-item relationship based on user behaviours. While existing representation learning methods primarily focus on optimising item-based mechanisms, such as attention and sequential modelling. However, these methods lack a modelling mechanism to directly reflect user interests within the learned item representations. Consequently, these methods may be less effective in capturing user interests indirectly. To address this challenge, we propose a novel Interest-aware Capsule network (IaCN) recommendation model, a model-agnostic framework that directly learns interest-oriented item representations... ...
