Improved example of CNN: Tiled CNN

(28th-September-2020)

CNN can acquire only simple shift invariance - Local receptive field + tied weights • Tiled CNN - Different filter from place to place ← Acquisition of invariance for more complex deformation - Topographic ICA (TICA)

Visual information processing of the brain

Structure of the visual cortex (ventral cortical visual pathway) - propagation with feedforward - hierarchy: simple feature extraction - to complex things - processing in the IT field: "grandmother cell" hypothesis and "population code" hypothesis
