Biostatistics Seminar Series, April 28, 2021


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.
