HAX712X: Software development for data science

(Almost) everything you need to know as an applied mathematician / statistician concerning coding and system administration.

Teachers

• Joseph Salmon : [email protected],
• Benjamin Charlier : [email protected]

This course material was improved with the help of some students including:

• Amelie Vernay
• Tanguy Lefort

Prerequisite

Students are expected to know basic notions of probabilities, optimization, linear algebra and statistics for this course. Some rudiments on coding is also expected (if, for, while, functions) but not mandatory.

Course description

This course focuses on discovering good coding practices (the language used being Python, but some element of bash and git will also be useful) for professional coding. A special focus on data processing and visualization will be at the heart of the course. We will mostly focus on basic programming concepts, as well as on discovering the Python scientific libraries, including numpy, scipy, pandas, matplotlib, seaborn. Beyond pandas ninja skills, we will also introduce modern practices for coders : (unitary) tests, version control, documentation generation, etc.

Grading

Tests: 20 % of the final grade

Short quiz of 20 min each (on Moodle). This will be a personal work.

• Quiz 1 BC (30/09/2022, 10%)
• Quiz 2 JS (28/10/2022, 10%)

Project: 80% of the final grade

Warning: the precise details of the projects might evolve before the allocation phase, and a precise grid will be given in the project section.

Warning: the project repository must show a balanced contribution between group members and intra-group grades variation could be made to reflect issues on the intra-group workload balance.

Bonus

1 supplementary point on the final grade of the course can be obtained for contributions improving the course material (practicals, Readme, etc.). See the Bonus section for more details on how to proceed.
