Modeling Implicit Communities from Geo-Tagged Event Traces Using Spatio-Temporal Point Processes
TL;DR: This is the first attempt at jointly modeling the diffusion process with activity-driven implicit communities and CoLAB achieves upto 27% improvements in location prediction task over recent deep point-process based methods on geo-tagged event traces collected from Foursquare check-ins.
Proceedings ArticleDOI
LBRR: Load Balanced Ring Routing Protocol for Heterogeneous Sensor Networks with Sink Mobility
TL;DR: A load balanced ring routing (LBRR) protocol for the large scale heterogeneous sensor networks with sink mobility support to balance the traffic load towards the mobile sink in a large densely deployed network is proposed.
Proceedings ArticleDOI
Region Invariant Normalizing Flows for Mobility Transfer
Vinayak Gupta,Srikanta Bedathur +1 more
TL;DR: In this article, a transfer learning framework called Reformd is proposed for continuous-time location prediction for regions with sparse checkin data, where the authors model user-specific checkin-sequences in a region using a marked temporal point process (MTPP) with normalizing flows to learn the inter-checkin time and geo-distributions.
Proceedings ArticleDOI
ProActive: Self-Attentive Temporal Point Process Flows for Activity Sequences
Vinayak Gupta,Srikanta Bedathur +1 more
TL;DR: ProActive is presented, a neural marked temporal point process (MTPP) framework for modeling the continuous-time distribution of actions in an activity sequence while simultaneously addressing three high-impact problems - next action prediction, sequence-goal prediction, and end-to-end sequence generation.
Journal ArticleDOI
Learning Temporal Point Processes for Efficient Retrieval of Continuous Time Event Sequences
TL;DR: This work proposes NEUROSEQRET which learns to retrieve and rank a relevant set of continuous-time event sequences for a given query sequence, from a large corpus of sequences, and develops two variants of the relevance model which offer a tradeoff between accuracy and efficiency.
