This is a fundamental course that covers basic concepts on algorithms, data structures and databases. This course spans two different tracks: one for students who have a major in Computer Science and another track for the rest.
During the first weeks, the course is different for both tracks. For the former, it introduces students to CS-specific advanced topics for Data Science, while for the latter it requires the students to cover basic material on algorithms, data structures and databases in a guided, yet autonomous learning manner.

The last part of the course (corresponding to the last 5 weeks) is common and it is structured as project-based learning. A statement about an end-to-end Data Science project will be delivered and students will need to create the required software infrastructure, using adequate tools.

The objective is to help students get a rigorous and strong knowledge required by the following master courses (for students with a minor in CS) or investigate further CS-specific topics for Data Science (for students with a major in CS). Last, but not least, the course promotes adopting good habits when creating software projects for Data Science in the final project.

Data Science Advanced Topics project (DS-AT project)

Students with a major in Computer Science will investigate on advanced topics specific for data science projects. For example, data quality, entity resolution, data integration, etc. Students with a minor in Computer Science will investigate and further study the fundamental concepts introduced in the lecturing hours.

Metodología docente

During the first 10 weeks, the students are divided in two tracks: one for students with a minor in computer science (track 1) and another one for students with a major in computer science (track 2).

Students in track 1 will study fundamental concepts in algorithms, data structures and databases. First, additional material to read, study and understand is provided. Students will have a large bank of exercises to practice their understanding on their own. Then, in the face-to-face lectures, the lecturer will solve doubts and go through representative exercises to guarantee a solid understanding. Also, for the most complex concepts, some regular teaching sessions will be scheduled.

Students in track2 will undertake a research project related to advanced topics of algorithms, data structures and databases within the context of data science. Relevant and critical problems such as data integration, entity resolution and data quality will be proposed. The student will have access to a description of the problem, some seminal research papers and reference tools in this matter.

The last 5 weeks of the semester is common for all students regardless of the track they followed during the first 10 weeks. During these weeks the course project takes place. Students must create a end-to-end system architecture to ingest, store, process, learn models and deploy such system for a realistic project with realistic data.

This course has a strong self-learning component. Complementing it, the lecturers will provide additional material, advice hours and complementary lectures and labs to guarantee a solid comprehension.

Método de evaluación

Let E1 be the score of the partial exam,
E2 the score of the final exam,
RPM the score of the DS-AT project and
CPM the score of the DS-EE project.

Then,

NE = MAX(E2, E1)
If the student followed track 1 (see methodology) then NT = NE
else if student followed track 2 (see methodology) then NT = RPM

The final mark will be 0.6*NT + 0.4*CPM
Transversal competences will weight a 0% in the final score.

Capacidades previas

This course assumes basic competences in algorithms, data structures and databases. The course is structured to cope with different backgrounds and learning needs but basic knowledge on Computer Science principles is assumed: notions of computer architecture, basic programming constructs and data structures.
