The Fred Hutch Biostatistics Program hosts seminars featuring presentations by Hutch and outside scientists to share their latest developments and recent research. Each seminar includes an hour-long presentation and discussion during which speakers showcase their work and findings.
This seminar will be held on Zoom due to the COVID-19 pandemic.
Biostatistics Seminar Series: “Sequential hotspots detection in the spatio-temporal systems”
In the first work, we will present our work focusing on sequential change and hotspot detection for spatio-temporal systems. In the first work, we propose an overall decomposition framework to detect the hotspots in the systems. We will discuss how such a decomposition framework can decompose the background into background components, anomaly (hotspots) components, and noise in different applications. In the second work, we will discuss the sequential change-point detection framework for the spatio-temporal system with limited sampling resources. We will discuss how the proposed method can balance exploration and exploitation by using the Multi-arm Bandit approach. We will also discuss the application of the proposed methods in manufacturing applications and infectious disease monitoring.
