Brain Tumor Classification from MRI Images Using a Multi-Scale Channel Attention CNN Integrated with SVM
This research introduces a novel hybrid model, MCACNN-SVM, for highly accurate brain tumor classification from MRI images. It combines a multi-scale channel attention Convolutional Neural Network (CNN) for robust feature extraction with a Support Vector Machine (SVM) for precise classification. The model leverages multi-scale kernels, channel attention for adaptive feature enhancement, and an optimized SVM classifier with a cosine annealing learning rate strategy. Extensive experiments demonstrate superior performance in accuracy, precision, recall, and F1-score compared to existing state-of-the-art methods.
