ONLY for students in EM Program in LCT, see http://ufal.mff.cuni.cz/lct.html. The aim of the course is to introduce elementary probabilistic and statistical principles, techniques and methods which are used in solving computational linguistics (natural language processing) tasks. An essential part of the course is active work with data and introduction to workflow in R while solving a given task. A part of the course will consist of individual study of mutually agreed selected materials.
Course completion requirements
Last update: RNDr. Martin Holub, Ph.D. (15.10.2017)

Students should regularly attend the classes and pass two written tests during the term and/or an assignement of a given task in R. Both theoretical knowledge and practical skills will be tested.
