Fig. 4: Normalized confusion matrix for STAI evaluation utilizing visual metrics and CNN-LSTM algorithm.
From: Identifying mental health status using deep neural network trained by visual metrics
Element value (m, n) of this matrix, and color, represent the probability of predicted STAI level n, given the ground-truth STAI level m, where m and n have labels of 0 (low), 1(intermediate/controllable), and 2 (high). The diagonal elements of this matrix correspond to correct predictions.
