The next phase is likely to focus on algorithms capable of learning from very few labeled examples ($n \\to 1$), like humans seem able to do. We propose an approach to this problem and describe the underlying theory, based on the unsupervised, automatic learning of a ``good'' representation for supervised learning, characterized by small sample complexity ($n$). We consider the case of visual object recognition though the theory applies to other do","authors_text":"Andrea Tacchetti, Fabio Anselmi, Jim Mutch, Joel Z.
