Dr. Ricardo Henao will introduce the basic concepts of machine learning with a focus on intuition and examples. The simpler and widely used logistic regression model will be introduced first, and from this, the multilayered neural network will be introduced as a generalization. Concepts of parameter learning (optimization), generalization (and overfitting), validation and performance evaluation […]
