It aims to select a small subset of relevant and informative features from the original feature space that may contain many irrelevant, redundant and noisy features. WebThe mid- and high-level visual properties supporting object perception in the ventral visual pathway are poorly understood. In the absence of well-specified theory, many groups have adopted a data-driven approach in which they progressively interrogate neural units to establish each unit's selectivity. Such methods are challenging in that they require …
