The Deep Learning Revolution
Book By TERRENCE J. SEJNOWSKI Sharks and Rays(Which include skates) are able to sense very weak electrical fields; indeed, they can detect the signal from a 1.5-volt battery clear across Atlantic Ocean. With this 6th sense, skates can navigate by the weak electrical signals from their motion through the earth's magnetic field, which generates microvolt signals in their electroreceptors. Hermann von Helmholtz was a nineteenth-century physicist and physician who developed a mathematical theory and an experimental approach to vision that forms the basis for our current understanding of visual perception. Vision is our most acute and also our most studied sense. With two frontal eyes, we have exquisite binocular depth perception, and half of our cortex is visual. In one tenth of a second, ten billion neurons in our visual cortex working together in parallel can identify a cup in a cluttered scene, even though we may have never seen that particular cup before and even when it m...
