Demo
Objective
https://www.kaggle.com/c/decoding-the-human-brain
Organized by: E. Olivetti, M. Kia, P. Avesani, N. Weisz (Univ. of Trento, IT),D. Wakeman (Harvard, USA), R. Henson (MRC/CBU, Cambridge, UK),O. Jensen (Donders Institute, NL), and A. Gramfort (Telecom ParisTech, CEA)
Objective
Every 1s or 2s
Can we classify if subject saw a face or scrambled face?
MEGSensor 1 (fT)
MEGSensor 2
(fT) xi s.t. yi = 1
xi s.t. yi = -1
Objective
Hacking time…
