Since the invention in 1980s, scanning probe microscopy (SPM) has been considered as the valuable avenue to visualize topography of sample in nanoscale. After more than 30-year development, SPMs have ...
A two-layer sparse coding model learns simple and complex cell receptive fields and topography from natural images
Independent component analysis Natural images Neural networks Spatial vision
