RnRTD: Intelligent Approach Based on the Relationship-Driven Neural Network and Restricted Tensor Decomposition for Multiple Accusation Judgment in Legal Cases

Algorithm 1

The solution of Problem 2 by using ALS Algorithm.

	Input: Tensor χ which represents the original legal case data, , the restricted tensor η, , and its weight .
	Output: The factor matrix sets and , , .
	Initialize the factor matrix sets and ;
	for to do
	// First, pick the elements in the factor set as variables
	for to K do
	;
	;

	end
	// Then, pick the elements in the factor set as variables
	for to K do
	;
	;
