Brain tumors, characterized by the uncontrolled and rapid proliferation of cells, can result in fatal outcomes if not identified and treated promptly. Consequently, the development of a reliable and automated diagnostic system is of paramount importance. In this study, a Fuzzy Convolutional Neural Network (F-CNN) is employed for the efficient diagnosis of brain tumors (Glioma, Meningioma, Pituitary, and non-tumors), leveraging the computational capabilities of Google Colaboratory. The methodology comprises four stages: pre-processing, training, testing, and evaluation. The pre-processing stage entails rescaling the image, resizing, random flipping, and random rotation. The training phase involves the construction of an intelligent model, encompassing four blocks: convolution, ReLU, batch normalization, and max pooling. This is followed by flattening, a fuzzy inferences layer, and a dense layer with dropout. The model was trained using a Kaggle dataset comprising 7022 brain tumor MRI images and validated with a test set of 470 MRI images sourced from the Neurological Wholesale Hospital in Baghdad. The proposed F-CNN model achieved a high accuracy rate of 99.31% while maintaining low computational complexity and time. This work illustrates the potential of Deep Learning approaches, such as F-CNNs, in enhancing the precision and efficiency of medical imaging diagnostics.
