Hi, I have 5 classes design. When I run multiclass SVM I am getting ~2 or 3 categories beyond chance results. However, when I run all pairs two classes classification, the results are beyond chance level in all the classifications (0.55-0.65 % hit rate). As far as I understand, this is a possible scenario with the major voting scheme of multiclass classification of all possible pairs. My question is how should one interpret such results? Doubtfully, I would prefer to get beyond chance level in mutliclass as well. However, since in pair classification I get beyond chance level, can it serve by itself an evidence for neural encoding scheme I try to decode?
Thanks for help, Vadim
