Learning as Extraction of Low-dimensional Representations

  title={Learning as Extraction of Low-dimensional Representations},
  author={Shimon Edelman and Nathan Intrator},
Psychophysical ndings accumulated over the past several decades indicate that perceptual tasks such as similarity judgment tend to be performed on a low-dimensional representation of the sensory data. Low dimensionality is especially important for learning, as the number of examples required for attaining a given level of performance grows exponentially with the dimensionality of the underlying representation space. In this chapter, we argue that, whereas many perceptual problems are tractable… CONTINUE READING
