A Model Based on Convolutional Neural Network for Online Transaction Fraud Detection

Algorithm 1

Find the best permutation of input features.
Input: The weight matrix , the rows of the weight matrix , initial state of the input
set , list of model accuracy rates , auxiliary sequence ( is the number of rows
below , satisfy the first condition ) and ( control the direction of
change)
Output: The best permutation of weight matrix.
