“…These interpretation problems are mainly caused by human issues, such as subjectivity and fatigue. On the other hand, computer-aided diagnosis (CAD) methods play a fundamental role in this task since they can support specialists with second opinions [8][9][10], especially regarding H&E images [5,8,[11][12][13][14][15][16][17].…”

“…The second group of descriptors consists of deep-learned (DL) features obtained using convolution neural networks (CNNs) [43]. This group has been useful for defining different CAD approaches [15,17,22,[44][45][46][47][48] that consider data representations with multiple levels of abstraction [8,47,49]. The most explored models have provided the best accuracy rates on the ImageNet dataset [50], such as AlexNet [51], GoogleNet [52], VGGNet [53], ResNet [54], Inception [52] and other applications [20,32,55].…”

“…It is essential to observe that EL models can be developed with the most relevant features, exploring a single selection stage to reduce the search space and increase the accuracy of the system [13,15,18]. The use of feature selection through two stages can also be implemented [61][62][63].…”

In this paper, we propose an approach based on ensemble learning to classify histology tissues stained with hematoxylin and eosin. The proposal was applied to representative images of colorectal cancer, oral epithelial dysplasia, non-Hodgkin’s lymphoma, and liver tissues (the classification of gender and age from liver tissue samples). The ensemble learning considered multiple combinations of techniques that are commonly used to develop computer-aided diagnosis methods in medical imaging. The feature extraction was defined with different descriptors, exploring the deep learning and handcrafted methods. The deep-learned features were obtained using five different convolutional neural network architectures. The handcrafted features were representatives of fractal techniques (multidimensional and multiscale approaches), Haralick descriptors, and local binary patterns. A two-stage feature selection process (ranking with metaheuristics) was defined to obtain the main combinations of descriptors and, consequently, techniques. Each combination was tested through a rigorous ensemble process, exploring heterogeneous classifiers, such as Random Forest, Support Vector Machine, K-Nearest Neighbors, Logistic Regression, and Naive Bayes. The ensemble learning presented here provided accuracy rates from 90.72% to 100.00% and offered relevant information about the combinations of techniques in multiple histological images and the main features present in the top-performing solutions, using smaller sets of descriptors (limited to a maximum of 53), which involved each ensemble process and solutions that have not yet been explored. The developed methodology, i.e., making the knowledge of each ensemble learning comprehensible to specialists, complements the main contributions of this study to supporting the development of computer-aided diagnosis systems for histological images.
