Before revision:  We evaluate STAM representations using classification and clustering tasks. Even though there are no prior approaches that are directly applicable to the UPLproblem, we evaluate the STAM architecture in comparison to some unsupervised and self-supervised deep learning approaches adapted in the UPL context .
