Webb15 juli 2024 · Slow Feature Analysis (SFA) extracts slowly varying features from a quickly varying input signal. It has been successfully applied to modeling the visual receptive fields of the cortical neurons. Sufficient experimental results in neuroscience suggest that the temporal slowness principle is a general learning principle in visual perception. Webb11 juni 2024 · sklearn-sfa or sksfa is an implementation of Slow Feature Analysis for scikit-learn.
