I directly don't want to dive into deep learning techniques for feature extraction. \nBut I am clueless on what would be some good feature descriptors (combinations as well) like SIFT or HOG , that would be useful for say training 9 binary classifiers for predicting the labels. \nMay be there could be some feature descriptor suiting a particular label and some other kind of descriptor suiting another label.\nI am amazed this hasn't been discussed on the contest's forum till now.</p>\n\n<p>Any kind of help would be really appreciated.
