The purpose is to gather each of class observation around the same area. In this loss function implementation it looks like 1 centre is created. So basically it forces all classes to be close to a single point. \r\n\r\nDid I understood this correctly ? \r\n\r\nEdit:\r\nthere is a stack-overflow post about this\r\nhttp://stackoverflow.com/questions/40162361/how-to-implement-center-loss-and-other-running-averages-of-labeled-embeddings\r\n"}}
