Takagi-Sugeno-Kang Fuzzy System by Yuqi Cui.
fuzzy_cluster.py: implementation of Fuzzy c-means (FCM) and Enhanced Soft Subspace Clustering (ESSC)
TSK_FS.py: implementation of TSK fuzzy system based on ridge classifier or logisitic regression classifier. The antecendent parameters are determined by ESSC instead of FCM, for its clustering ability in high dimensional data space.
