Environmentally Sustainable Productionaussian linear regression, choosing an L2 penalty leads to ridge regression and choosing an L1 penalty leads to the Lasso. The same penalties can be applied to logistic regression. Both penalties tend to reduce the magnitude of coefficients. Because the L1 penalty can reduce coefficients to zero, th

Such n-gram variables lead to a large number of variables. The data are also sparse –most entries are zero– because most words do not appear in most texts. The use of stemming,

However, kNN is slow for large data sets and memory hungry. The tuning parameter . regulates the bias-variance tradeoff, and kNN is sensitive to scaling. The case study classi

We discuss a number of common activation functions that contribute nonlinearity in an otherwise linear network. We cover vanishing and exploding gradients, weight initialization—to attenuate the vanishing gradient problem—stochastic gradient descent usin
