MASTER'S IN MATHEMATICS

Partial differential equations (PDEs) are now an essential mathematical tool for studying and understanding physical and biological phenomena. Their extreme complexity often makes them impossible to solve analytically, hence the need to use numerical methods.

This course is devoted to an introduction to EDPs, followed by their solution using well-known numerical methods such as the finite difference and finite volume methods. A section focused more on analysis—necessary for the introduction to the finite volume method—will be devoted to the analytical solution of scalar conservation laws. Four programming lab sessions will use simple examples to illustrate the scientific computing tools covered in class.

The construction of solutions to partial differential equations (PDEs) and the theoretical study of their qualitative behavior are based primarily on the use of results from analysis, particularly functional analysis. This course introduces key tools for solving PDEs from analytical or geometric perspectives. These tools will be applied in the study of several examples of PDEs representative of major classes of equations.

This course is a continuation of the optimization course offered in the second semester of the third year of the bachelor’s program.

After reviewing the results and numerical methods for first- and second-order optimization problems—both unconstrained and subject to equality and inequality constraints—the course focuses on topics currently of interest in industrial optimization, particularly robust, multi-criteria optimization under uncertainty.

The course then illustrates the role of optimization in the main machine learning algorithms. These topics are illustrated with examples of classification and regression problems in supervised learning. These examples provide an opportunity to discuss metrics and procedures for evaluating learning, validation, and inference (cross-validation, overfitting, etc.).

The course introduces the different types of learning: unsupervised, supervised, transfer learning, reinforcement learning, incremental learning, etc.

Topics related to database management are covered: generation, imputation, visualization, and segmentation.

The course explores the connections between transfer learning in mathematics and numerical simulation to address issues such as the generation of synthetic datasets, imputation, non-intrusive prediction, fast inference, and more.

The course includes a significant number of ongoing computer projects. All sessions take place in a computer-based environment and allow students to immediately apply the theoretical concepts they have learned.

This course is a continuation of the optimization course offered in the second semester of the L3 Mathematics program and the course on optimization and machine learning in the M1 MANU program. The course builds on the concepts covered in other modules of the MANU master’s program in PDE analysis and numerical simulation.

Following a review of the results and numerical methods for the numerical simulation of PDEs on adaptive meshes, results on a posteriori error estimation, and supervised learning methods covered in the M1 program, the course focuses on the generation of high-quality databases and their completion and certification through certified numerical simulation based on error control.

This issue is fundamental to the certified use of machine learning in industry. Indeed, the accuracy of mathematical learning during inference depends heavily on the quality of the database.

The course includes a significant number of ongoing computer projects. All sessions take place in a computer-based environment and allow students to immediately apply the theoretical concepts they have learned.

We study inverse problems, emphasizing the concept of a “well-posed problem.”

First, inverse problems in finite dimensions are introduced (the concepts of conditioning, singular values, etc.), followed by those in infinite dimensions (problem stability, regularization, pseudo-inverse, etc.).

Next, we review the properties of the Fourier transform and the convolution operation in Lp spaces and their usual subspaces. We examine how these two operations lead to well-posed or ill-posed problems. For convolution, in particular, the concepts of “filter” and “deconvolution” are discussed in the context of signal and image analysis.

Finally, we apply these concepts to the study and inversion of the Radon transform—or related transforms—derived from medical imaging techniques.

This course prepares students for the modeling exam in Option C of the external mathematics certification exam. This exam, which is based on the analysis of texts, focuses on the connections between algebra and symbolic computation. The symbolic computation software SageMaths is used in this course.

The topics covered are those of Option C’s curriculum: representation and algorithmic manipulation of common mathematical objects in algebra and formal computation (integers, floating-point numbers, integers modulo n, polynomials, matrices); machine-imposed limitations (space and time optimization, the concept of algorithmic complexity), and application areas for these theories (error-correcting codes, cryptography, information processing and data compression, geometry, etc.).

Classical algorithms (fast exponentiation, extended Euclidean algorithm, Hörner's scheme, Gauss's algorithm, modular methods, primality tests, etc.) are introduced in class and then explored on the computer using SageMath software. This is also an opportunity to become familiar with this software.

Each student is required to present one or more oral lessons—depending on the requirements of the agrégation—based on texts from previous years.

The first part of this course covers additional topics in probability theory: conditional expectation and Gaussian vectors. The second part introduces one of the main families of discrete-time stochastic processes: Markov chains. These are sequences of dependent random variables, whose dependency relationship is relatively simple since each variable depends only on the previous one. They are also a very powerful modeling tool. We will study the main properties of these processes, as well as their long-run behavior and the estimation of their parameters.

Statistical data sets are becoming increasingly large. Before modeling them, it is essential to explore them and reduce their dimensionality while losing as little information as possible. This is the objective of this course on multidimensional exploratory statistics. Methodologically, the tools used in this course are primarily those of Euclidean geometry. Statistical problems and concepts will therefore be translated into the language of Euclidean geometry before being addressed within that framework. The two families of exploratory methods that will be covered in this course are:

1) automatic classification methods, which group observations into classes and reduce the variability among the observations to the variability between these classes;

2) principal component analysis methods, which identify the main directions of variation among the observations and enable the generation of interpretable, low-dimensional representations of this variation.

The importance of statistical science in the process of scientific discovery and industrial advancement lies in its ability to enable the formulation of inferences about phenomena of interest, to which risks of error or levels of confidence can be assigned. The calculation of these error risks is based on probability theory, but the principles and methods for associating these risks with inferences constitute a theoretical framework that serves as the foundation for all statistical methodologies.

This module is intended to provide a fairly comprehensive overview of these basic principles and the mathematical tools, results, and theorems used in inferential statistics. It covers the concepts of point and interval estimation, hypothesis testing, and fundamental concepts such as exponential families, the maximum likelihood principle, and the use of the p-value.
For implementing certain applications, appropriate tools from the R software package will be presented.

Statistical modeling is based on two fundamental concepts: information (which is to be extracted from data) and decision-making (which is to be carried out based on that data). This course provides an introduction to the theoretical formalization of these two concepts. It is therefore logically placed at the beginning of the program, as many other courses subsequently draw on these concepts and results.

This course provides an introduction to stochastic control. In this type of
problem, the goal is to modify the natural trajectory of a process to achieve a certain
objective. We will focus on discrete-time decision-making Markov processes, in which we can
choose an action at each time step. We will explore how to formalize stochastic control problems within this framework and how to solve them both theoretically and numerically.

This introductory course on time series—that is, a sequence of observations made over time—provides an essential toolkit for analyzing this type of data, which is frequently encountered in a wide range of applications: pollutant concentrations in the air over time, blood glucose levels over time, product sales at a supermarket, stock prices on the stock market, etc. This course focuses both on the mathematical presentation of concepts and on the more technical aspects of implementing these methods. Numerical examples are provided using the R software.

Nonparametric methods are important in many statistical applications because they allow us to move beyond traditional approaches that require the specification of valid statistical models. However, establishing the validity of such a model is a complex undertaking. 

Nonparametric methods circumvent this problem by transforming the data into ranks and conditioning on certain quantities derived from the observed distribution of these ranks. The statistics constructed in this way are independent of the distribution of the raw data, which allows for the development of statistical inference procedures that are independent of the underlying model of the data. Furthermore, the loss of statistical efficiency is minimal.
 
This course provides a fairly comprehensive overview of nonparametric methods. It builds upon an introductory course on parametric inferential methods by adapting and expanding the theory behind several advanced concepts, such as conditional tests, the comparative power of tests (measures of effectiveness), and the concept of “effect size.” It emphasizes the practical application of these methodologies by providing an overview of the main R commands and their uses.

The linear model is a tool that is both simple and very powerful, forming the basis of many statistical methods. Mastering and thoroughly understanding it is very useful both from a practical standpoint—for conducting detailed analyses of certain datasets—and from a conceptual standpoint—for understanding the theoretical foundations of more advanced machine learning methods, including those currently in use.
 
This course offers an introduction to simple and multiple linear regression models, using both quantitative and qualitative variables. It presents the formal derivation and theoretical analysis of least squares and maximum likelihood estimators in the Gaussian case. It also provides tools for validating and selecting variables to explore the model’s limitations. Finally, it introduces the practical application of this tool to simple datasets using the R software.

This course introduces the general framework of linear models, in which we seek to express a response variable as a function of a linear combination of predictors. By assuming both a specific relationship between the mean response and the predictors (link function) and a specific distribution of the random variation in the response around its mean, it is possible to model binary data (e.g., presence/absence, mortality/survival) or count data (e.g., number of individuals, number of species). Using this general framework, it is then possible to model non-normally distributed variables. The use and interpretation of logistic, binomial, and Poisson regression models will be discussed in detail.

After presenting the Bayesian paradigm, we will examine point estimates and ensemble estimates, followed by a discussion of the Bayesian model selection methodology. Binomial, Gaussian, and linear models will be used to illustrate the preceding topics.

For complex models, the problems of estimation and model selection in the Bayesian context require the use of advanced tools for approximating integrals. Therefore, the second part of the course will focus on Monte Carlo methods and Markov Chain Monte Carlo algorithms.

In biostatistics, the lifespan of an individual—or, in reliability analysis, the lifespan of a component—is a quantity whose statistical analysis differs from that of typical data. On the one hand, it involves considering quantities such as the random function and the mean remaining lifetime, among others, which are not as relevant in other areas of statistics. On the other hand, it often involves a censoring mechanism, since the data are incomplete due to the length of the experiments relative to the time allotted for them.

The purpose of this module is to present the basics of survival analysis. The rationale for survival analysis and the main mechanisms of data censoring are discussed. Two main types of statistical approaches are presented: the parametric approach, which, despite its limitations, is often preferred by users because “the parameters speak for themselves”; and the nonparametric approach, which reinforces and complements parametric analyses by providing greater flexibility and depth when dealing with large datasets. The module also presents various models (the Cox model, the accelerated failure rate model, etc.) that link survival to explanatory factors, thereby identifying those that may impact survival. This information is particularly useful in a healthcare context, as it allows for the personalization of an individual’s survival projections.

These methods will be implemented using the R software.
