Basic process of logistic regression and actual combat of iris project

1, Basic process of logistic regression 1. Logistic regression Learn the law from multiple eigenvalues of a group of samples, establish a model (the learning model is abstracted as a formula f(x)), and use this model to predict the results of other samples. Logistic regression is to classify the prediction results. Logistic regression steps: (1 ...
