Faculty: Faculty of Computer Science

Educational Programme: Master of Data Science (Master)

Final Grade: 10

Year of Graduation: 2024

In the era of big data, the quality of data has become paramount for effective decision-making and analytics across various industries. Traditional data cleaning methods, often manual and labor-intensive, struggle to cope with the volume, velocity, and variety of modern datasets, leading to significant challenges in maintaining data accuracy and reliability. This study introduces an innovative automatic data cleaning tool developed as a Python package, designed to integrate deep learning techniques to enhance the efficiency and effectiveness of data preprocessing. By leveraging models capable of learning intricate patterns and dependencies within data, the tool automates the identification and correction of common data quality issues such as outliers, missing values, and inconsistencies in data types. Tested across diverse datasets, including customer transactions, social media interactions, and healthcare records, the tool demonstrates substantial capabilities in improving data quality with minimal human intervention. The results indicate that this approach not only streamlines the data cleaning process but also significantly reduces the time and effort required, allowing data scientists to focus more on analysis rather than data preparation. This paper details the development process, the underlying technology, and the evaluation of the tool's performance, offering insights into its potential applications and benefits in various data-driven industries. The proposed solution marks a significant advancement in the field of data management, suggesting a shift towards more automated and intelligent systems for maintaining data integrity in the digital age.
