WebApr 10, 2024 · In this method, there is a training data set and a test data set. For each test datum, classification parameter (\(\widehat{\alpha }\) is in Eq. 3) is calculated. The new test sample attaches onto subspaces of each class, and the distance between the test sample and the class-specific subspace is calculated.
