Before revision:  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 .
After revision:  Even though there are no prior approaches that are directly applicable to the UPLproblem, we evaluate the STAM architecture with two recent continual learning models, Memory Aware Synapses (MAS) and Gradient Episodic Memories (GEM), after adapting them in the UPL context .
