Quantum mechanics describes the smallest scales of energy levels of atoms/waves and subatomic particles/waves. * Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large macroscopic scale. * Quantum mechanics differs from classical physics in that energy, momentum, angular momentum and other quantitiesContinue Reading

Gradient is a vector that is made up from a the derivatives of multi-variate function. Gradient of an Image = ∇f = [∂f/∂x,∂f/∂y] The gradient of a function is the vector direction/angle of the most rapid increase in Intensity(Getting Brighter), and the magnitude of that vector is how much itContinue Reading

R Squared is the coefficient of determination it normally ranges from 0 to 1, and provides a measure of how well observed outcomes, are replicated by the model.   The formula is: Residual(Error) sum of squares (RSS), also known as (SSR) , is the sum of the squares of theContinue Reading
