Image Classification
ELI5 — The Vibe Check
Image classification is teaching a computer to look at a picture and say what it is — 'that's a cat,' 'that's a dog,' 'that's a suspicious mole you should get checked.' It's one of the oldest and most solved problems in AI. The moment a neural network beat humans at classifying images (2015), the deep learning revolution was officially on.
Real Talk
Image classification assigns a label or category to an entire input image. Approaches range from traditional CNNs (ResNet, EfficientNet) to modern Vision Transformers (ViT, DeiT). Pre-trained models on ImageNet or larger datasets provide strong transfer learning baselines. It's used in medical imaging, content moderation, quality inspection, and countless other applications.
