Disentangling Stellar Mass and Environmental Effects on eROSITA AGN Activity using multi-wavelength data from GAMA, WISE, GALEX, and DESI Legacy Survey
Navya Saraswat, Shadab Alam, Subhabrata Majumdar
We use a stellar-mass complete sample of galaxies from GAMA/eFEDS to test whether AGN activity depends on environment independent of stellar mass. To isolate this e…
Semantic Consistency for Assuring Reliability of Large Language Models
Harsh Raj, Vipul Gupta, Domenic Rosati +1
Large Language Models (LLMs) exhibit remarkable fluency and competence across various natural language tasks. However, recent research has highlighted their sensitivity to variatio…
Network Security Modelling with Distributional Data
Subhabrata Majumdar, Ganesh Subramaniam
We investigate the detection of botnet command and control (C2) hosts in massive IP traffic using machine learning methods. To this end, we use NetFlow data -- the industry standar…
Towards Algorithmic Fairness in Space-Time: Filling in Black Holes
Cheryl Flynn, Aritra Guha, Subhabrata Majumdar +2
New technologies and the availability of geospatial data have drawn attention to spatio-temporal biases present in society. For example: the COVID-19 pandemic highlighted dispariti…
Exploring diffuse radio emission in galaxy clusters and groups with the uGMRT and the SKA
Surajit Paul, Ruta Kale, Abhirup Datta +13
Diffuse radio emission has been detected in a considerable number of galaxy clusters and groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic par…
Measuring Reliability of Large Language Models through Semantic Consistency
Harsh Raj, Domenic Rosati, Subhabrata Majumdar
While large pretrained language models (PLMs) demonstrate incredible fluency and performance on many natural language tasks, recent work has shown that well-performing PLMs are ver…
