Abstract: To exceed limited capacity of established convolutional neural network(CNN) with fixed architecture in traditional surface feature extraction in remote sensing images, we propose a new feature extraction method based on architecture-variant convolutional neural network (AVCNN). In AVCNN, key units are variables and the performance of the unknown model become object function. That means architecture search is added before traditional weights solving. Genetic algorithm is introduced to search proper architecture and classical algorithm is used to solve unknown weights in the candidate CNN. The CNN with final architecture is used to extract the surface feature in remote sensing images. The experiment result shows that AVCNN has flexible capacity and performances well in surface features extraction in remote sensing images.
