Data Preprocessing

Course guarantor:

Lecturer:

Tutor:

Supervisor:

Department of Applied Mathematics

Synopsis:

Students learn to prepare raw data for further processing and analysis. They learn what algorithms can be used to extract parameters from various data sources, such as images, texts, time series, etc., and learn the skills to apply these theoretical concepts to solve a specific problem in individual projects - e.g., parameter extraction from image data or from Internet.

Requirements:

Fundamentals of statistics, FCD course in data mining.

The recommended prerequisite is BIE-VZD.

Syllabus of lectures:

1. Data exploration, exploratory analysis techniques, visualization of raw data.

2. Descriptive statistics.

3. Methods to determine the relevance of features.

4. Problems with data ? dimensionality, noise, outliers, inconsistency, missing values, non-numeric data.

5. Data cleaning, transformation, imputing, discretization, binning.

6. Reduction of data dimension.

7. Reduction of data volume, class balancing.

8. Feature extraction from text.

9. Feature extraction from documents, web. Preprocessing of structured data.

10. Feature extraction from time series.

11. Feature extraction from images.

12. Data preparation case studies.

13. Automation of data preprocessing.

Syllabus of tutorials:

1. Assignment of course projects.

2. Consultations.

3. Presentation of course projects.

Study Objective:

Data preprocessing is crucial for successful data processing and takes a lot of time - usually more than the data processing itself. Knowledge of algorithms for extraction of parameters from various data sources is a fundamental part of knowledge engineering,
