Course details

Learn how large language models (LLMs) can be used as practical assistants in everyday data science work. Start by seeing LLM-generated code in action and then build your own reusable helpers that speed up repetitive tasks such as exploration, preprocessing, and boilerplate modeling. Find out how to use LLMs to generate code that can be inspected, executed, and validated, rather than trusting black-box outputs. Explore how LLMs behave in classification and regression tasks and how to evaluate those results using standard data science metrics.

Learning objectives
Build reusable LLM-powered helpers that generate inspectable Python code for common data science tasks.
Use LLMs effectively across key stages of the data science workflow, including exploration, preprocessing, modeling, and evaluation.
Apply LLMs to classification and regression tasks using prompt-based approaches and validate the results with standard metrics.
Decide when to rely on LLM assistance and when human judgment, validation, and domain knowledge are required.
