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.
Aim of the course -
Last update: Jirát Jiří Ing. Ph.D. (31.01.2014)

Students will be able to:

Apply knowledge of algorithms for extraction of parameters from various data sources as a fundamental part of knowledge engineering,
