Evaluation of M2 courses

For your information, here are the modalities of evaluation for all M2 courses.

CR01: The students are given research articles twice. Each time, they give an oral presentation based on these articles. The first one counts as continuous evaluation (CE), the second one as final evaluation (FE). The final note is given by (CE+2FE)/3.

CR02: There is homework for continuous evaluation (CE). The students are given research articles, they produce a written report and give an oral presentation based on these articles (FE). The final note is given by (CE+2FE)/3.

CR03: There is homework for continuous evaluation (CE). The students are given research articles, they produce a written report and give an oral presentation based on these articles (FE). The final note is given by (CE+2FE)/3.

CR04: There is homework for continuous evaluation (CE). The students choose research articles, they produce a written report and give an oral presentation based on these articles (FE). The final note is given by (CE+FE)/2.

CR05: 3 homeworks for continuous evaluation (CE); written report and give an oral presentation based on a research article for final evaluation (FE). The final note is given by (CE+2FE)/3.

CR06: Two mini-projects counting each for 1/4 of the final grade. One final exam counting for the last half.

CR07: Two homeworks for continuous evaluation (CE1,CE2). The students are given research articles, they produce a written report and give an oral presentation based on these articles (FE). The final note is given by ((CE1+CE2)/2+2FE)/3.

CR08: Grades will be based on a final exam and on the presentation of a research article, each contributing to one half of the grade.

CR09: The students are given research articles, they produce a written report (WR/20) (between 8 and 20 pages). We will do a cross review. One report of another given student report (1 or 2 pages maximum) will be done (RR/20). And student gives an oral presentation based on these articles (OP/5). Questions should be done by students (Q/5). The final note is given by (3WR+3OP+2*(RR+Q))/7

CR10: The students are asked to write a static analyser for a mini language (AS). The students are given research articles, they give an oral presentation based on these articles (FE). The final note is given by (AS+FE)/2.

CR11: There will be a programming project (6pts, due after the mid-term break), a modeling project (7pts, due after the end-of-term break) and a written exam (7pts).

CR12: The final grade for the CR12 course is computed as follows: small exercices to be handed each week, during the first half of the course, count for 1/4 of the grade; a mid term exam counts for 1/4 of the grade; a final exam counts for 1/2 of the grade.

CR13: There is homework for continuous evaluation (CE). The students have also a final evaluation (FE) based on a written exam at the end of the course. The final note is given by max(FE,(CE+2FE)/3).

CR14: There is homework (based on the content of lectures as well as the study of research papers) for continuous evaluation (CE). There is a written exam (2h) for final examination (FE). The final note is given by (CE+2FE)/3.

CR15: The evaluation of the CR15 Complex Networks course will depend on whether the student is involved in the M2 Complex System program or not. If yes then the student’s participation will be mandatory to the TD, which is evaluated through projects during the semester and the final mark will count as 1/3 to the final overall mark. In addition every student has to pass a written exam by the end of the semester for the lecture, which will count with 2/3 weight in the final evaluation. If the student is not involved in the Complex System program only the written exam is mandatory, which result will determine 100% the final mark. On the other hand even these students have the option to participate to the TDs, complete the projects and get a TD mark. In this case the student will have the advantage to gain the better mark gained with or without the TD results.

CR16: The students will be proposed research articles about which they need to produce a report (with some numerical applications of the content of the article) and an oral presentation. The report and presentation are used for the note.

CR17: Two homeworks (counting each for DM/2) and one final exam (DS). The final grade is (DM+2DS)/3.

CR18: The students are given 3 homework assignments for continuous evaluation (CE). At the end of the semester, students are asked to study and orally present research articles (FE). The final note is given by (CE+2FE)/3.

CR19: There is homework for continuous evaluation (CE). The students are given research articles, they produce a written report and have an exam based on these articles (FE). The final note is given by (CE+2FE)/3.

The main page of the course can be found here.

The course aims to provide basic skills for analysis and statistical modeling of data, with special attention to machine learning both supervised and unsupervised. An important objective of the course is the operational knowledge of the techniques and algorithms treated, and for this aim the lectures will focus on both theoretical and practical aspects of machine learning, and for the practical part it is required to have a good knowledge of programming, preferentially in Python language. The expected outcomes include (1) understanding the theoretical foundations of machine learning and (2) ability to use some Python libraries for machine learning in the context of simple applications.

Topics will include:

– The major paradigms of learning from data, the learning problem, the feasibility of learning
– The architecture of machine learning algorithms: model structure, scoring, and model selection ­ The theory of generalization, model complexity, the approximation­generalization tradeoff, bias and variance, the learning curve
– Score functions and optimization techniques. Gradient descent and stochastic gradient descent.
– Validation and Cross­Validation: validation set, leave­one­out cross validation, K­fold cross­validation
– Linear Models: linear classification, linear regression, ordinary least squares, logistic regression, non­linear transformations
– Non­linear models for classification: support vector machines, tree models, nearest­neighbor methods, Naive Bayes
– Overfitting and Regularization: model complexity and overfitting, commonly used regularizers, Lasso.
– Unsupervised learning: cluster analysis, the K­means algorithm, hierarchical clustering
– Feature selection and dimensionality reduction: Singular Value Decomposition, Matrix Factorisation
– Information retrieval, text representation and classification, term weighting

Overview of the theoretical aspects of machine learning will be followed by the application of algorithms in real problems such as: image classification, text mining, spam detection… The exercises will be implemented with the help of an interactive Python environment, with the use of standard tools for data analysis and visualization, such as the Scientific Python stack, Scikit­Learn, Pandas and NLTK.

Evaluation: personal projects with oral presentation

Modes of interaction, all along the year.

For administrative matters, please contact Amel Zagrarni (secrétariat du Département d’Informatique). To discuss scientific/academical matters, as well as your training period, your future, etc., you can contact your tutor (the list of tutors is here), or Daniel Hirschkoff. Your délégués (representants of the students) are Victor Hublitz, Raphaël Monat and Étienne Moutot. Remember that you are supposed to read your email @ens-lyon.fr — in case of a technical problem, get in touch as soon as possible with the Direction des Systèmes Informatiques).

Next year

  • Préparation à l’agrégation { this information is not relevant if you don’t speak french } : il y a 12 ECTS à valider par le biais de modules de professionalisation.Cette page, qui sera régulièrement mise à jour, décrit l’ensemble des cours qui sont proposés (ainsi que les modalités d’inscription). À noter que cela peut être une bonne idée de valider ces modules l’année qui précède la préparation à l’agrégation, mais on ne peut pas les valider plus d’un an en avance (si vous souhaitez préparer l’agrégation après le M2, c’est en M2 que vous pourrez suivre et valider ces modules).
    Les gens qui ont manifesté un intérêt potentiel/hypothétique pour la préparation à l’agrégation l’an prochain sont: Carette Titouan, Combette Guillaume, Faron Maxime, Iannetta Paul, Lajou Dimitri, Lebeau Fabrice, Lucas Christophe, Mauras Simon, Ohlmann Pierre, Perrotin Elise, Seif Johanna
  • M2: you might be interested in applying for the M2 at ENS Lyon, but maybe also somewhere else, depending on your scientific interests. It is up to you to find out about the corresponding application procedure, and about the dates. Usually applications can be made around may-june. (You may well apply to several Masters, be accepted in several places, take your decision during the summer, and inform everybody of your choice — including places where you don’t go)
    Important notice: alas, it might be the case that you will not validate your M1, or that you validate it but will not be accepted to our local M2. It is up to you to judge whether you run the risk of ending up in this situation or not. It is also up to you to be prepared for all possibilities, and, if applicable, to apply to a different Master, at M1 level. Do it in advance, september is usually too late.

Computational Complexity

Computational Complexity

Course offered in the second semester of M1.

Overview of the course:

Computational complexity aims to classify computational problems depending on the resources they need. One
studies various modes of computation such as deterministic, randomized, nondeterministic or quantum and compares
resources such as time or space needed to solve algorithmic problems. The objective of this course is to give a
broad understanding of the notions used to classify computational problems. About half of the course is dedicated
to studying basic complexity classes defined using Turing machines. We introduce (or study deeper) notions that are
central in complexity theory: nondeterministic computation (e.g., the class NP), reductions between computational
problems (e.g., NP-completeness) and the technique of diagonalization (e.g., hierarchy theorems). We also study
randomized computation and computation using boolean circuits as well as their relation to basic complexity classes.
We conclude the course by studying the complexity of communication, i.e., trying to evaluate communication
bottlenecks to perform a given computational task between different parties.
Teaching in 2014: Omar Fawzi (lectures) and S ́ebastien Maulat (exercise classes)

Course objectives:

One can summarize the most important objectives of the course as follows.

  1. Understand the formal definitions for the basic complexity classes like L, NL, P, NP, coNP, PSPACE.
    Be familiar with nondeterministic computation and the polynomial hierarchy. Know about the inclusions and separations between these classes.
  2. Understand the notion of reduction between computational problems, and the notion of complete problem, e.g., SAT is NP-complete, PATH is NL-complete, TQBF is PSPACE-complete.
  3. Understand complexity classes defined using boolean circuits, and the notion of uniformity in computation. Know the relation to basic complexity classes.
  4. Understand complexity classes using randomized computations. Know the relation to basic complexity classes.
  5. Get a flavour for the power of interactive proofs.
  6. Be familiar with an important tool in theoretical computer science: communication complexity. Be able to reduce various problems to a communication complexity problem.
