WebMar 5, 2024 · MMD-Isomap is a supervised multi-manifold learning method over Isomap [ 26 ]. The algorithm uses the global pairwise constraints [ 32, 33, 34, 35, 36] to solve the optimization problem. In the pairwise constraints, some pairs of points are in same class and their relationships are recorded in the must-Link (ML) set. WebOct 1, 2024 · Traditionally, DR is performed using a linear technique that aims to learn a projection matrix from the given data, such as principal component analysis (PCA) [5], semi-supervised discriminant analysis (SDA) [6] and linear discriminant analysis (LDA) [7]. However, linear techniques cannot adequately handle complex nonlinear data. jimmy nash homes for rent
