Évènement

This week will be devoted to statistical learning from both the theoretical and applied perspectives. Statistical learning theory has been developed in the 70’s and brought a great revival in statistics. On the one hand, the development of computer science and tools allowed massive data collection, and implementation of powerful algorithms which are often memory and computation time consuming. On the other hand, classical asymptotic theory used to prove the efficiency of estimation methods in modeling and prediction was limited by dimensionality problems.
The approaches developed in statistical learning helped to face some new challenges such as the curse of dimensionality, small sample size, and now massive  datasets. Data mining, feature selection, and more recently Big data appeared as specialized approaches for massive datasets modeling and analysis.
In addition to the theoretical developments (non asymptotic theory), many algorithms emerged in statistics and computer science to meet these new needs which arised in many areas such as bioinformatics, social sciences, medicine or telecommunications.
This week aims to bring together specialists from statistical learning working on advanced techniques and coming from different fields, mainly statistics, but also computer science, social science and bioinformatics.
The main topics of interest include:

• Supervised learning
• Unsupervised learning: clustering and density estimation
• Model selection
• Big data
