Project Background:
The project on mutual information estimation explores relationships and dependencies between variables within complex datasets. Mutual information is crucial to quantify the shared information or entropy between variables. By estimating mutual information, it aims to unveil hidden patterns, correlations, or dependencies within the data. This process involves analyzing different data sources and extracting insights about how changes in one variable relate to or impact changes in another. It utilizes advanced statistical and computational techniques, including information theory principles and potentially machine learning algorithms, to accurately estimate mutual information. Such estimations play a vital role in diverse fields, such as feature selection, dimensionality reduction, and understanding the structure of complex systems.
