MFA: Marginal Fisher Analysis

详 情 说 明

MFA stands for Marginal Fisher Analysis. It is a statistical technique used in machine learning and data analysis to find the linear combination of features that best separates two or more classes of data. This method is particularly useful when dealing with high-dimensional data, where the number of features is much greater than the number of samples. The objective of MFA is to find a projection onto a lower-dimensional space that maximizes the difference between the means of the classes while minimizing the variance within each class. By doing so, MFA can help to identify the most relevant features for discriminating between different groups of data. Overall, MFA is a powerful tool for analyzing complex datasets and has applications in a wide range of fields, from computer vision to bioinformatics.
