Old Casette Players

Nowadays no body using cassette player. I bought a cassette to listen music from my smartphone . It would be good if we can build an equipment to replace cassette player and allows user to connect his smartphone directly to this equipment. Than smartphone could be used as GPS, television or music player.

Wrong Normal Assumption on Linear Classifiers;

Normal assumption on weight vectors regularizes the by some precision matrix gamma. However normal distribution takes Mahalonobis distance , thus it fails to capture scaled version of weight vector.Also, If weight vectors assumed to be unit vectors than they will be distributed on unit hyper-sphere. It may worth to use von-misses distribution , but I think it will not differ too much.
