ExPERT: Modeling Human Behavior Under External Stimuli Aware Personalized MTPP

AAAI 2025technical

Marked Temporal Point Process (MTPP) -- the de-facto sequence model for continuous-time event sequences -- historically employed for modeling human-generated action sequences, lack awareness of external stimuli. In this study, we propose a novel framework developed over Transformer Hawkes Process (T…

Graph-based semi-supervised learning through the lens of safety

UAI 2021poster

Graph-based semi-supervised learning (G-SSL) algorithms have witnessed rapid development and widespread usage across a variety of applications in recent years. However, the theoretical characterisation of the efficacy of such algorithms has remained an under-explored area. We introduce a novel algor…

Understanding the Success of Graph-based Semi-Supervised Learning using Partially Labelled Stochastic Block Model

IJCAI 2020poster

With the proliferation of learning scenarios with an abundance of instances, but limited amount of high-quality labels, semi-supervised learning algorithms came to prominence. Graph-based semi-supervised learning (G-SSL) algorithms, of which Label Propagation (LP) is a prominent example, are particu…
