Before revision:  To solve the UPL problem , we propose an architecture that involves an online clustering module , called Self-Taught Associative Memory (STAM). Layered hierarchies of STAM modules learn based on a combination of online clustering, novelty detection, URLetting outliers, and storing only prototypical representations rather than specific examples.
