WebbThe slowness principle is a hypothesis for the functional organization of the visual cortex and possibly other sensory areas of the brain (Wiskott et al. 2011) and it has been introduced as a way to model the transformation invariance in natural image sequences (Zhang Zhang and Dacheng Tao 2012). Webb1 jan. 2011 · Slow feature analysis (SFA) is a bioinspired method for extracting slowly varying driving forces from quickly varying non-stationary time series. We show here that it is possible for SFA to detect...
The slowness principle is based on the observation that different representations of a sensorial input vary on different time scales. For instance, a zebra grazing in the savanna is a scene that changes slowly. This scene is represented in the eyes of an observer in terms of activities of retinal receptors, which, due to … Visa mer Most learning algorithms based on the slowness principle are online learning rules, i.e., they improve the extracted features incrementally with each time step of the … Visa mer SFA has been developed for learning invariant representations of moving objects in a feedforward model of the visual system. It has been shown that a … Visa mer WebbThis principle is called the slowness principle. Methods and results We have chosen to approach this principle in a very direct way: we consider a large abstract set of functions and extract the ones that applied to sequences of natural images have the most slowly varying output (as measured by the mean of the squared derivative).
WebbThe slowness principle is a concept inspired by the visual cortex of the brain. It postulates that the underlying generative factors of a quickly varying sensory signal change on a different, slower time scale.

WebbThe second principle, the principle of slowness (introduced by Földiak [2], promoted and developed by Wiskott [17]), states that sensory signals vary more quickly than their signi–cance. Consider the visual impressions caused by a fa-miliar complex object, like a tree on the side of the road or a person acting in a movie.
