The final values are training error = 0.005 NSE (blue), and selection error = 0.195 NSE (orange). assign (sepal_ratio = lambda x: (x ["SepalWidth"] / x ["SepalLength"])). More specifically, we want to find a neural network with a selection error of less than 0.195 NSE, which is the value that we have achieved so far. Anderson carefully measured the anatomical properties of samples of three different species of iris, Iris setosa, Iris versicolor, and Iris virginica. Linear discriminant analysis is a method you can use when you have a set of predictor variables and you'd like to classify a response variable into two or more classes.. The next figure is a graphical representation of this classification neural network: The fourth step is to set the training strategy, which is composed of: The loss index chosen for this application is the They represent 60% (90), 20% (30), and 20% (30) of the original instances, respectively, and are randomly split.
