A biologically plausible neural network for Slow Feature Analysis

WebbThis paper develops a kernelized slow feature analysis (SFA) algorithm. SFA is an unsupervised learning method to extract features which encode latent variables from time series. Generative relationships are usually complex, and current algorithms are either not powerful enough or tend to over-fit. Webb9 juni 2024 · Intuitively, the complexity of dynamic textures requires temporally invariant representations. Inspired by the temporal slowness principle, slow feature analysis (SFA) extracts slowly varying features from fast varying signals [].For example, pixels in a video of dynamic texture vary quickly over the short term, but the high-level semantic … Webb8 apr. 2024 · Applications: examining cells, tissues, microorganisms, and other small samples.
