SONIC: Synergizing VisiON Foundation Models for Stress RecogNItion from ECG signals

no code implementations31 Mar 2024 Orchid Chetia Phukan, Ankita Das, Arun Balaji Buduru, Rajesh Sharma

Stress recognition through physiological signals such as Electrocardiogram (ECG) signals has garnered significant attention.

Heterogeneity over Homogeneity: Investigating Multilingual Speech Pre-Trained Models for Detecting Audio Deepfake

1 code implementation31 Mar 2024 Orchid Chetia Phukan, Gautam Siddharth Kashyap, Arun Balaji Buduru, Rajesh Sharma

To validate our hypothesis, we extract representations from state-of-the-art (SOTA) PTMs including monolingual, multilingual as well as PTMs trained for speaker and emotion recognition, and evaluated them on ASVSpoof 2019 (ASV), In-the-Wild (ITW), and DECRO benchmark databases.

From Simulations to Reality: Enhancing Multi-Robot Exploration for Urban Search and Rescue

no code implementations28 Nov 2023 Gautam Siddharth Kashyap, Deepkashi Mahajan, Orchid Chetia Phukan, Ankit Kumar, Alexander E. I. Brownlee, Jiechao Gao

In this study, we present a novel hybrid algorithm, combining Levy Flight (LF) and Particle Swarm Optimization (PSO) (LF-PSO), tailored for efficient multi-robot exploration in unknown environments with limited communication and no global positioning information.

Reinforcement Learning-based Knowledge Graph Reasoning for Explainable Fact-checking

no code implementations11 Oct 2023 Gustav Nikopensius, Mohit Mayank, Orchid Chetia Phukan, Rajesh Sharma

Extensive experiments on FB15K-277 and NELL-995 datasets reveal that reasoning over a KG is an effective way of producing human-readable explanations in the form of paths and classifications for fact claims.

A Comparative Study of Pre-trained Speech and Audio Embeddings for Speech Emotion Recognition

no code implementations22 Apr 2023 Orchid Chetia Phukan, Arun Balaji Buduru, Rajesh Sharma

In this work, we exploit this research gap and perform a comparative analysis of embeddings extracted from eight speech and audio PTMs (wav2vec 2. 0, data2vec, wavLM, UniSpeech-SAT, wav2clip, YAMNet, x-vector, ECAPA).

"Can We Detect Substance Use Disorder?": Knowledge and Time Aware Classification on Social Media from Darkweb

no code implementations20 Apr 2023 Usha Lokala, Orchid Chetia Phukan, Triyasha Ghosh Dastidar, Francois Lamy, Raminta Daniulaityte, Amit Sheth

We use the Drug Abuse Ontology, state-of-the-art deep learning, and knowledge-aware BERT-based models to generate sentiment and emotion for the social media posts to understand users' perceptions on social media by investigating questions such as: which synthetic opioids people are optimistic, neutral, or negative about?
