Introduction to Data Science Statistical Methods

This course gives an overview of the statistical methods used by data scientists, with an emphasis on the applicability to business problems. No software is shown in the course, and the mathematical details are kept to a minimum.

Apprendre à

• Identify the need for feature engineering such as sampling, variable transformations, imputation, and variable selection.
• Describe applications of supervised models such as decision trees, neural networks, support vector machines, factorization machines, and logistic regression.
• Describe the usefulness of unsupervised models such as clustering, text mining, network analysis, and path analysis.
• Implement model assessment and deployment such as visualization and monitoring.
