Data Science 1: Introduction to Data Science

APCOMP 209A Subject & Catalog Number

Description

Data Science 1 is the first half of a one-year introduction to data science. The course focuses on the analysis of messy, real-life data to make predictions using statistical and machine learning methods. Material covered integrates the five key facets of an investigation using data: (1) data collection – data wrangling and cleaning to obtain a suitable dataset; (2) data management – accessing data quickly and reliably; (3) exploratory data analysis – generating hypotheses and building intuition; (4) prediction or statistical learning – developing and applying models such as linear and logistic regression, k-nearest neighbors, decision trees, and probabilistic approaches based on Bayes’ rule; and (5) communication – summarizing results through visualization, storytelling, and interpretable summaries.

This is the first part of a two-course sequence. The curriculum builds throughout the academic year, and students are strongly encouraged to enroll in both the fall and spring courses within the same academic year.
