Binary mass function derivation
WebNov 15, 2024 · Since scaling a function does not change a function’s maximum or minimum point (eg. minimum point of y=x² and y=4x² is at (0,0) ), so finally, we’ll divide the negative log-likelihood function by the total number of examples ( m) and minimize that function. Turns out it's the Binary Cross-Entropy (BCE) Cost function that we’ve been … WebThe famous de Moivre’s Laplace limit theorem proved the probability density function of Gaussian distribution from binomial probability mass function under specified conditions. De Moivre’s Laplace approach is cumbersome as it relies heavily on many lemmas and theorems. This paper invented an alternative and less rigorous method of deriving …
