AutoML for Networks

Automatically design neural networks.

Search Space

Cells: building blocks. Operations: conv, pooling, attention. Connectivity: how cells connect.

Search Strategies

Random search: baseline. Grid search: inefficient. Evolutionary: mutate, select. Reinforcement: reward accuracy.

Efficient Methods

Weight sharing: share weights across architectures. Early stopping: prune unpromising. DARTS: differentiable search.
