Jump to: navigation, search


The logistic regression classification algorithm with LASSO (L1) or ridge (L2) regularization.


   Data: input dataset
   Preprocessor: preprocessing method(s)


   Learner: logistic regression learning algorithm
   Model: trained model
   Coefficients: logistic regression coefficients

Logistic Regression learns a Logistic Regression model from the data. It only works for classification tasks.


   A name under which the learner appears in other widgets. The default name is “Logistic Regression”.
   Regularization type (either L1 or L2). Set the cost strength (default is C=1).
   Press Apply to commit changes. If Apply Automatically is ticked, changes will be communicated automatically.


The widget is used just as any other widget for inducing a classifier. This is an example demonstrating prediction results with logistic regression on the hayes-roth dataset. We first load hayes-roth_learn in the File widget and pass the data to Logistic Regression. Then we pass the trained model to Predictions.

Now we want to predict class value on a new dataset. We load hayes-roth_test in the second File widget and connect it to Predictions. We can now observe class values predicted with Logistic Regression directly in Predictions.
