A large number of algorithms for classification can be phrased in terms of a linear function that assigns a score to each possible category k by combining the feature vector of an instance with a vector of weights, using a dot product.The predicted category is the one with the highest score. The method of least squares is a standard approach in regression analysis to approximate the solution of overdetermined systems (sets of equations in which there are more equations than unknowns) by minimizing the sum of the squares of the residuals (a residual being the difference between an observed value and the fitted value provided by a model) made in the results of Supervised: Supervised learning is typically the task of machine learning to learn a function that maps an input to an output based on sample input-output pairs [].It uses labeled training data and a collection of training examples to infer a function. Much of machine learning involves estimating the performance of a machine learning algorithm on unseen data. A distribution has the highest possible entropy when all values of a random variable are equally likely.
