Signature Verification

Validation Set• PCA needs samples to calculate the projectioncoefficients– Using data from the training or testing sets will bias the results• Divide data into training, validation, and testing• SVC 2004– 40 users: 20 genuine signatures, 20 skilled forgeries per user.– Testing procedures:• Train on 5 genuine signatures• Test on 10 genuine signatures• Test on 20 skilled forgeries• Test on 10 random forgeries• 2-Fold Cross Validation– Select data from the second half of 20 users (genuine, skilled)for validation set to train PCA– Test on the first half of 20 users with the calculated coefficients– Repeat this process, switching the 2 groups
