Webpyclustering provides Python and C++ implementation almost for each algorithm, method, etc. C++ implementation is used by default to increase performance if it is supported by target platform (Windows 32, 64 bits, Linux 32, 64 bits, MacOS 64 bites) otherwise Python implementation is used. WebTo provide more external knowledge for training self-supervised learning (SSL) algorithms, this paper proposes a maximum mean discrepancy-based SSL (MMD-SSL) algorithm, which trains a well-performing classifier by iteratively refining the classifier using highly confident unlabeled samples. The MMD-SSL algorithm performs three main steps. First, a multilayer …
