The spatial receptive fields of simple cells in mammalian striate cortex havebeen reasonably well described physiologically and can be characterized as beinglocalized, oriented, and bandpass, comparable to the basis functions of wavelettransforms. Previously, we have shown that these receptive field properties maybe accounted for in terms of a strategy for producing a sparse distribution ofoutput activity in response to natural images (Olshausen and Field, 1996a).Here, in addition...

    • ...Predictive coding itself is a specific example of more general theories of efficient encoding or redundancy reduction (Attneave, 1954; Barlow, 2001; Olshausen & Field, 1996b, 1997) and of hierarchical perceptual inference or analysis-by-synthesis (Barlow, 1994; Friston, 2005, 2009; Lee & Mumford, 2003; Mumford, 1992; Yuille & Kersten, 2006); hence, PC/BC can be related to these wider frameworks for understanding cortical function...
