5. Glossary

Algorithm

A sequence of instructions for solving a problem. In AI, algorithms perform complex tasks such as data classification and analysis, enabling machines to adjust their models and improve their performance.

Principal component analysis

Dimensionality reduction technique for simplifying and visualizing complex data. It projects data onto variance-maximizing principal components, useful for eliminating noise and reducing complexity.

Machine learning

A branch of AI where models learn from data. By detecting patterns in the data, they improve their predictions without being explicitly programmed for each task.

Apprentissage non supervisé; unsupervised learning

Technique where the model discovers structures in unlabeled...
