'''Contacts:''' All the questions should be addressed to '''bayesml@gmail.com'''. Theme of any letter must contain the following tag: '''[HSE NBM19]'''. Letters without the tag will be most probably lost in the inbox.

We also have a chat in Telegram. Its main language is Russian because there will be students from two other programs. However, we will answer in English all the questions in English. All important news will be announced in English in the chat and also sent to the group e-mail. If you don't feel comfortable to use such bilingual chat you may skip it and use your group e-mail to read announcements and course e-mail to ask us any questions.

===Course description=== 
This course is devoted to Bayesian reasoning in application to deep learning models. Attendees would learn how to use probabilistic modeling to construct neural generative and discriminative models, how to use the paradigm of generative adversarial networks to perform approximate Bayesian inference and how to model the uncertainty about the weights of neural networks. Selected open problems in the field of deep learning would also be discussed. The practical assignments will cover implementation of several modern Bayesian deep learning models.

===Grading System===

The assessment consist of 3 practical assignments and a final oral exam. Practical assignments consist in programming some models/methods from the course in Python and analysing their behavior: VAE, Normalizing flows, Sparse Variational Dropout. At the final exam students have to demonstrate knowledge of the material covered during the entire course.

Final course grade is obtained from the following formula: 

О_final = 0,7 * О_cumulative + 0,3 * О_exam,

where О_cumulative is an average grade for the practical assignments. 

All grades are in ten-point grading scale. If О_cumulative or О_final has a fractional part greater or equal than 0.5 then it is rounded up. 

===Assignments  ===
* The course contains three practical assignments. Solutions should be submitted to [https://anytask.org/course/444 anytask]. To get the invite, please write to the course e-mail. The site has an interface only in Russian, so non-Russian speaking students may submit their solutions to the course e-mail. In this case, the subject line of the letter in addition to the tag should contain your name, surname and assignment number.
* All assignments should be coded in Python 3.
* Students have to complete all assignments by themselves.  Using a code of your colleagues or code from open implementations are prohibited and will be considered as plagiarism. All involved students (including those who share his solution) will be severely punished.
* Assignments are scored up to 10 points. Each assignment has a deadline, a penalty is charged in the amount of 0.3 points for each day of delay, but in total not more than 6 points. Usually you will have 2 weeks to solve an assignment. Some assignments may contain bonus parts.

Approximate dates for assignments: TBA

At the end of the module before the exam there will be a hard deadline for all assignments! Exact date will be announced later.
