A practical pipeline builds a Chihuahua vs muffin classifier from web images using Keras: roughly 500 images per class, train/validation/test splits, on-batch training with data augmentation and dropout to fight overfitting, and runtime around 16s per epoch on a GTX1060. Accuracy jumps to ~99.47% when using transfer learning with VGG16 pretrained on ImageNet. Model inspection uses LIME local interpretability to find spurious background features; warnings include biased training datasets and metrics that mask skewed classes.
