DecMeg2014 data analysis competition Biomag 2014 Decoding Challenge - Brain Decoding Across Subjects https://www.kaggle.com/c/decoding-the-human-brain Decoding mental states from functional neuroimaging data is a data analysis paradigm adopted both in neuroscience studies and in brain-computer interface applications. Decoding means determining, from the recorded brain activity, what stimulus was provided to a subject. In this competition, a large number of trials, from a face vs. scrambled face visual task, are available from multiple subjects. The brain activity was recorded by means of magnetoencephalography (MEG). MEG recordings from various subjects and the category of the associated visual stimuli are given to the participants of the competition in order to train their prediction algorithms. With their algorithms, the participants will have to predict the category of the stimulus of a different set of MEG recordings, from other subjects. Each submission to the competition will be scored according to the accuracy of prediction. Decoding across subjects is a difficult task because of the variability in head shape, cortical folding and functional organisation. For MEG data, the literature on decoding across subjects is still in early stages and this competition aims at raising the awareness about this complex scientific problem. This competition is associated with the the 19th International Conference on Biomagnetism, Biomag 2014, Halifax (Canada), August 24-28, 2014. The competition begins: April 21st, 2014. The competition ends: July 27th, 2014. Prizes: 1st 3,000 USD, 2nd 1,500 USD, 3rd 500 USD.
