The document discusses the concept of representations in computer vision, examining their necessity, types, and how they are assessed for utility in machine learning algorithms. It poses several critical questions regarding optimal representations, their computation, and biological parallels in memory storage. Additionally, it references various academic fields and papers related to statistics, information theory, biology, computer architecture, cognitive science, and philosophy that contribute to this discourse.

If not, can it be approximated? • What do animals store in memory? How? • … About representation A. Ortis - Representations for CV
