Supervised Machine Learning with Python : Develop Rich Python Coding Practices While Exploring Supervised Machine Learning.
A supervised learning task infers a function from flagged training data and maps an input to an output based on sample input-output pairs. In this book, you will learn various machine learning techniques (such as linear and logistic regression) and gain the practical knowledge you need to quickly an...
