Derivation of Least Squares Regressor and Classifier
NettetThen, the population genetic structure was inferred (target values). Cross-validation: the training dataset was used to train the machine learning models, while the test dataset was used for validating the models. PLS-DA—partial least squares discriminant analysis; MLP—multilayer perceptron; CNN—convolutional neural network. NettetFurthermore, the in performing Newton's method one can also compute the Hessian of the Least Squares cost by hand. Moreover since the cost is a convex quadratic only a single Newton step can completely minimize it. This single-Newton-step solution is often referred to as minimizing the Least Squares cost via its normal equations. pool filtration system parts
