The zyBooks Approach

Less text doesn’t mean less learning.

Data Science Foundations provides an interactive introduction to common algorithms and techniques in data science. This zyBook covers data preprocessing, regression techniques, supervised and unsupervised learning algorithms, decision trees, neural networks, ensemble methods, and model evaluation techniques.

“It is already clear that this represents the future of programming text books. Its basic expository content is the equal of any paper text, but it really shines in using the natural advantages of online vs. static teaching material ­ animation and interactivity ­ to excellent effect, giving the student an additional dimension of insight.”
