When to Review: Spaced Repetition for Continual Pre-Training of Language Models
Alankar Atreya, Devesh Batra, Yoages Kumar Mantri +3
Continual pre-training of large language models must acquire new information without erasing old knowledge. Existing replay methods often choose a global old/new mixture and sample…
Large-Scale ChatBot Validation Through Customer Digital Twin Simulations
Cristovao Iglesias, Devesh Batra, Alankar Atreya +7
LLM-based chatbots are transforming customer service in regulated domains such as banking, but scalable and cost-effective validation remains a critical barrier to safe deployment.…
Helping Customers in Distress: An LLM-powered Agent that Converses, Probes, and Routes
Alankar Atreya, Stefan Sylvius Wagner, Stefan Sylvius Wanger +8
Banks receive millions of reports of fraud, scams, and disputed transactions every year, making it challenging to accurately direct customers to the appropriate specialist teams fo…
How Personality Traits Shape LLM Risk-Taking Behaviour
John Hartley, Conor Hamill, Devesh Batra +3
Large Language Models (LLMs) are increasingly deployed as autonomous agents, necessitating a deeper understanding of their decision-making behaviour under risk. This study investig…
Conformal Predictions for Longitudinal Data
Devesh Batra, Salvatore Mercuri, Raad Khraishi
We introduce Longitudinal Predictive Conformal Inference (LPCI), a novel distribution-free conformal prediction algorithm for longitudinal data. Current conformal prediction approa…
