Use cases

  • Quick prototyping of neural network architectures
  • Transfer learning with pre-trained ImageNet models
  • Educational ML courses and tutorials
  • Production model training via TensorFlow backend

Anti-patterns / when NOT to use

  • Less control than raw TensorFlow/PyTorch
  • Custom training loops can be awkward
  • Debugging keras layers is indirect

Replaces / alternatives to

  • Fast.ai
  • proprietary ML APIs
