Human brain is an amazing organ and one of the greatest computers! There is a lot to be learnt from the way brain handles signal. Most of our sensory signal is preprocessed by an organ called hypothalamus. One of the preprocessing that it applies on signal is scaling it into a log-scale. So that, signal near point of interest is sampled finely and signal far off are sampled coarsely. One of our work was on pre-processing of images with a log-polar scale (the way thalamus does with the signal from eye) and check its implications on machine learning (ML) algorithms.
