Overview of the feature-oriented deep convolutional neural network. Overview of the feature-oriented deep convolutional neural network training to better preserve small features in output. The weight map is used to assign different weights to different voxels in the loss function calculation. In this case, a higher weight is assigned to voxels in the lesion
