SMoG
====

Example implementation of the Synchronous Momentum Grouping (SMoG) paper. 
SMoG follows the framework of contrastive learning but replaces the contrastive
unit from instance to group, mimicking clustering-based methods. To
achieve this, they propose the momentum grouping scheme which synchronously 
conducts feature grouping with representation learning.
