DESCRIPTION:Dr Oualid Benkarim presents\, 'The cost of untracked diversity 
 in brain-Imaging prediction'. \n\nRegistration available here. \n\nSpeaker
 : Oualid Benkarim\, Ph.D.\n\nThe Neuro\, 91µ¼º½ÊÓƵ\n\nAbstract: Br
 ain-imaging research enjoys increasing adoption of supervised machine lear
 ning for single-subject disease classification. Yet\, the success of these
  algorithms likely depends on population diversity\, including demographic
  differences and other factors that may be outside of primary scientific i
 nterest. In this talk\, I will discuss our recent work on using propensity
  scores as a composite confound index to quantify diversity due to major s
 ources of population stratification. I will show\, across various analysis
  scenarios\, the extent to which cross-validated prediction performances a
 re interlocked with diversity\, the relationship of diversity with the ins
 tability of extracted brain patterns\, and the role of prevailing deconfou
 nding practices in mitigating the full consequences of population diversit
 y.\n\nBio:  Oualid Benkarim is a postdoctoral researcher at the Montreal N
 eurological Institute of 91µ¼º½ÊÓƵ. Previously\, he obtained his P
 hD in Information and Communication Technologies from Pompeu Fabra Univers
 ity\, Spain and a MSc in Artificial Intelligence from University of Barcel
 ona\, Spain. His research focuses on biomedical image analysis and machine
  learning\, with a particular interest in the study of neurodevelopmental 
 disorders and the development of robust and generalizable methods for dise
 ase classification.\n\n\nThe Feindel Virtual Brain and Mind (VBM) Seminar 
 Series will advance the vision of Dr. William Feindel (1918–2014)\, Former
  Director of the Neuro (1972–1984)\, to constantly bridge the clinical and
  research realms. The talks will highlight the latest advances and discove
 ries in neuropsychology\, cognitive neuroscience\, and neuroimaging.\n\nSp
 eakers will include scientists from across The Neuro\, as well as colleagu
 es and collaborators locally and from around the world. The series is inte
 nded to provide a virtual forum for scientists and trainees to continue to
  foster interdisciplinary exchanges on the mechanisms\, diagnosis and trea
 tment of brain and cognitive disorders.\n
