Exercise

Changing the model coefficients

When you call fit with scikit-learn, the logistic regression coefficients are automatically learned from your dataset. In this exercise you will explore how the decision boundary is represented by the coefficients. To do so, you will change the coefficients manually (instead of with fit), and visualize the resulting classifiers.

A 2D dataset is already loaded into the environment as X and y, along with a linear classifier object model.

Instructions

100 XP
  • Set the two coefficients and the intercept to various values and observe the resulting decision boundaries.
  • Try to build up a sense of how the coefficients relate to the decision boundary.
  • Set the coefficients and intercept such that the model makes no errors on the given training data.
