Data reduction is a research area that involves techniques and methodologies for reducing the amount of data without significantly affecting the integrity of the information contained within it. This process may involve filtering, aggregation, sampling, and summarization of data to make it more manageable and easier to analyze. Data reduction can help in simplifying complex datasets, improving efficiency in data storage and processing, and making it easier to extract valuable insights from the data. This research area is essential in fields such as data mining, machine learning, and big data analytics.
