By combining Theorem 2 and Lemma 3, we can derive the proof of Corollary 4. Let There are 2 kinds of cells in the search space, including normal cells and reduction cells. After a reduction cell, the channel number is doubled. Cells are stacked sequentially to build a network. We use a set of 8 different candidate operations, including: 3 3 separable convolution; 5 5 separable convolution; 3 3 dilated separable convolution; 5 5 dilated separable convolution; 3 3 max pooling; 3 3 average pooling; identity (i.e. All the operations follow the ReLU-Conv/Pooling-BN pattern except identity and zero.
