How does deep learning work?

functional mapping of pixels

• nto objects is very complicated

deep learning is solving this issue by breaking up the problem into series of nested simple mappings

Step 1: provide trained network such that

• thers can use it for prediction

Step 2: provide trained network for new classification task (transfer learning) Step 3: completely retrain network on new dataset Step 4: completely retrain network under data privacy constraints
