Data Science Foundations

O čem to celé bude?

Are you interested in learning more about data science but don’t know where to start? This course will provide you with the key foundational knowledge any data scientist needs. It will prepare you for your career start in data science or further advanced learning in the field. 

In this course, you will learn about the various activities that data scientists do. 
Do you want to predict if a bank transaction was fraudulent or not? Do you want to forecast your company sales in the upcoming months, so that enough inventory is prepared? Or do you want to assess what chemical compound has the biggest impact on production of a protein that is used for your company's newly developed drug?
We will show you how to do all of that! We will walk you through multiple types of real-world data science projects. You will learn about selecting suitable methods for solving each of these tasks, how these methods work, and on which use cases they can be applied.

What will you learn?

  • Data Science fundamentals - data science and business thinking, an overview of machine learning problems and related solution methods, principles of data modelling – how data should be structured, train/test data split, model selection, and validation.
  • Testing hypotheses, for example, if a drug is effective in stopping disease, or if company investment in sustainability has a positive impact on its profits: linear regression, panel data regression – fixed and random effects.
  • Solving classification tasks such as classifying bank transactions as fraudulent or not: Logistic regression, Decision Trees, Support Vector Machines methods.
  • Solving regression tasks such as predicting train delays: Regression Trees, Support Vector Regressions, Random Forest methods.
  • Forecasting time series data such as pollution levels or country's population growth: stationarity concept, ARIMA, and Exponential Smoothing methods.
  • Finding unseen patterns in your data, for example creating segments of your customers: Principal Component Analysis, k-means clustering, Hierarchical clustering.

Who is this course for?

  • For people interested in data science and for those who want to get into the data science field.
  • For people who still remember high school math a bit – terms like correlation or weighted average should sound familiar.

How do you finish the course?

You will attend at least 7/9 lectures.
