Deep Recurrent Neural Network Performing Spectral Recurrence on Hyperspectral Images for Brain Tissue Classification

Published: 27 April 2023 Publication History

Abstract

Hyperspectral imaging approaches have proven its effectiveness in the medical field for characterizing brain tissues. Furthermore, these techniques in conjunction with machine learning (ML) algorithms has shown to be a useful tool for tumor detection in order to assist neurosurgeons in operations. In this report, it is proposed a novel deep recurrent neural network (DRNN) performing spectral recurrence with the hyperspectral bands to increase precision in tissue classification. In addition, this research present a comparison between the optimized models of the followings ML algorithms: support vector machine, random forest (RF) and the DRNN. All of them were trained by following an hyperparameter optimization process. As a result, DRNN improve brain tissue predictions in terms of the area under the receiver operating characteristic objective test metric (by 1.39% over SVM and 1.91% over RF) whereas RF classification maps illustrate truthfully the distribution of different tissue regions.
