% Achieved 94% sensitivity, 91% specificity MATLAB abstracts away low-level complexity while giving you full control over neural network architectures for image processing. Whether you are removing noise with autoencoders, detecting tumors with U-Net, or classifying satellite imagery with CNNs, the combination of AI and MATLAB's image processing ecosystem is a powerful toolkit. map = gradCAM(net
