Data processing – organising a dataset

A micro-certificate confirms practical skills in working with data from the very start of the data collection process. This applies to situations where we receive a raw dataset and prepare it for further analysis.

This was followed by the creation of a comprehensive and automated data processing pipeline. Finally, at least two machine learning models were built and compared. The project culminated in the creation of an interactive dashboard designed to facilitate an accessible understanding of the data and support the decision-making process. The assignment served as a summary and practical culmination of the course material, as well as an opportunity to expand knowledge of additional functions using the Python language.\n\nNumber of ECTS credits: 1\n\nAdditional information: The micro-certificate is part of the Computer Science degree programme, specialising in Artificial Intelligence.The classes were held in computer labs equipped with Python software.","id":"https://openbadgefactory.com/v1/badge/_/TIMQ5Ua2AOWGa10CE/criteria.html?v=2.0&c_id=8cb3170ab03a2b7ea152c1c6f059dad2e1c996c6ab3e8625c6fe8eefece39574"},"type":["Achievement"],"name":"Data processing – organising a dataset","description":"A micro-certificate confirms practical skills in working with data from the very start of the data collection process.
