 ###### Grothendieck inequalities
• Introduce the mathematical formalism necessary to understand some of the most used algorithms in Forecasting through regressions and time series.

• Invite the student to understand the need and the advantages of regularization in linear regressions.

• Motivate the use of time series as a method to correctly model some phenomena.

• Teach the statistical and computational qualities of the proposed algorithms.

• Introduce the concept of anomaly and those algorithms useful in its detection.
