Gaussian Pyramid for Nonlinear Support Vector Machine
| Input: D: the training dataset (xi, yi), k: the size of the Gaussian pyramid must be an odd number | | Output: find an optimal hyperplane | | Start | | Step 1: data preprocessing on D | | Step 2: build the correlation matrix of D by equation: | | | | Step 3: randomly generate a Gaussian pyramid as a k × k matrix between 0 and 1 | | Step 4: reduce the size of D using K to produce Dnew, a new training dataset, by equation: | | | | Step 5: find the multivariate normal distribution of Dnew by the following probability density function: | | | | Step 6: classify Dnew to find an optimal hyperplane and build the model to classify new data points. | | End |
