Optimal Multi-Level Interval-based Checkpointing for Exascale Stream Processing Systems
Sachini Jayasekara, Aaron Harwood, Shanika Karunasekera
State-of-the-art stream processing platforms make use of checkpointing to support fault tolerance, where a "checkpoint tuple" flows through the topology to all operators, indicatin…
A Utilization Model for Optimization of Checkpoint Intervals in Distributed Stream Processing Systems
Sachini Jayasekara, Aaron Harwood, Shanika Karunasekera
State-of-the-art distributed stream processing systems such as Apache Flink and Storm have recently included checkpointing to provide fault-tolerance for stateful applications. Thi…
USTAR: Online Multimodal Embedding for Modeling User-Guided Spatiotemporal Activity
Amila Silva, Shanika Karunasekera, Christopher Leckie +1
Building spatiotemporal activity models for people's activities in urban spaces is important for understanding the ever-increasing complexity of urban dynamics. With the emergence…
Dynamic Graph Configuration with Reinforcement Learning for Connected Autonomous Vehicle Trajectories
Udesh Gunarathna, Hairuo Xie, Egemen Tanin +2
Traditional traffic optimization solutions assume that the graph structure of road networks is static, missing opportunities for further traffic flow optimization. We are intereste…
Multi-spatial Scale Event Detection from Geo-tagged Tweet Streams via Power-law Verification
Yi Han, Shanika Karunasekera, Christopher Leckie +1
Compared with traditional news media, social media nowadays provides a richer and more timely source of news. We are interested in multi-spatial level event detection from geo-tagg…
