Algorithms for Data Analysis
This course is inspired by the one written by Charlotte Laclau who kindly granted me her source files. So far, I use the same jupyter notebooks. Note that it will evolve over the next few years according to feedback from students and teachers.
Prerequisites
It is necessary to have prior knowledge on both the fundamentals of mathematics (analysis, linear algebra, probability, statistics) and computer science. As such, it is advised to be proficient in
- the manipulation of vectors and matrix multiplication
- probability distributions (common distributions, mean, variance, etc.)
- the basics of the calculus of variations
Educational Goals
This course is designed to provide a quick introduction to data analysis algorithms for data engineers. As such, it meets different educational objectives:
- Understand the differences between artificial intelligence and machine learning
- Know which model / algorithm to choose depending on the task
- Learn how to train, validate and test machine learning models
- Discover the basics of numerical optimization
- Master data analysis Python librairies
- Apply the most popular supervised learning algorithms (linear regression, SVM , decision trees, etc.)
- Use two unsupervised learning algorithms (K-means, PCA)
