  : Ali Shojaie\, PhD\, Professor of Biostatistics\, Adjunct Professor of 
 Statistics\, University of Washington TITLE : "Estimation and Inference f
 or Networks of Multi-Experiment Point Processes" ABSTRACT: Modern high-di
 mensional point process data\, especially those from neuroscience experim
 ents\, often involve observations from multiple conditions and/or experim
 ents. Networks of interactions corresponding to these conditions are expe
 cted to share many edges\, but also exhibit unique\, condition-specific o
 nes. However\, the degree of similarity among the networks from different
  conditions is generally unknown. To address these needs\, we propose a j
 oint estimation procedure for networks of high-dimensional point processe
 s that incorporates easy-to-compute weights in order to data-adaptively e
 ncourage similarity between the estimated networks. We also propose a pow
 erful hierarchical multiple testing procedure for edges of all estimated 
 networks\, which accounts for the data-driven similarity structure of the
  multi-experiment networks. Compared to conventional multiple testing pro
 cedures\, our proposed procedure greatly reduces the number of tests and 
 results in improved power\, while tightly controlling the family-wise err
 or rate. Unlike existing procedures\, our method is also free of assumpti
 ons on dependency between tests\, offers flexibility on p-values calculat
 ed along the hierarchy\, and is robust to misspecification of the hierarc
 hical structure.\n\nSpeaker:\nAli Shojaie\, PhD\n\nAdmission:\nFree\n\nDe
