Teaching language

Suitable for English-speaking students

Objectives

This unit has as main objectives to provide an introduction to the main data science methodologies and also to convey knowledge on programming and tools for data analysis using R language.

Learning outcomes and competences

This unit should provide the students with: 
1. theoretical competences on several basic methodologies of data science. 
2. competences regards developing software for data science tasks. 
3. practical competences on applying datas cience techniques to specific problems. 

Working method

Eligibility for exams

Students must participate either on the two tests of the unit or on the final exam, composed by two parts corresponding to the contents of test1 and test2.

Calculation formula of final grade

The assessment of the unit is distributed without final exam and it is composed by two (2) theoretical tests, and two (2) practical assignments, one group assignment and one individual assignment.

The final grade is given as a weighted average of the theoretical and practical grades using the following formula:

GFinal = 0.60 * GradeTheory + 0.30 * GradePract

where, GradeTheory is the average of the grades on the two theoretical tests or of the final exame and GradePract is given by the grade of the practical assignments, namely using the following weighted average: GradePract = 0.7*GradAss1 + 0.3*GradAss2

There will be 2 tests during the semester. These are not compulsory, but if you obtain at least the minimum grade (35% or 7 out of 20) in both tests, and your final grade (GFinal) is positive (≥9.5), you do not need to go to the final exam. Otherwise, you GradeTheory will be given by your grade at the final exam.

Examinations or Special Assignments

The theoretical tests will take place in two thereotical classes, one in the middle of the semester and the other at the end of it.

The 1st practical assignment will be announced in the middle of the semester and should be completed by the end of the semester. The 2nd practical assignment will be announced later and should also be delivered by the end of the semester.

Special assessment (TE, DA, ...)

Students that are in special situations according to the legislation, can arrange to have tests and exams in dates other than the regular ones.

Classification improvement

The student can improve in the theoretical grade by taking the final exam

Observations

All of the provided material (e.g. slides, recommended books) is given in English and if there are foreign students the classes will also be given in English.
