Extracting class activation maps (CAM) from a classification model often results in poor coverage on foreground objects, i. e., only the discriminative region (e. g., the "head" of "sheep") is recognized and the rest (e. g., the "leg" of "sheep") mistakenly as background.

Specifically, due to the sum-over-class pooling nature of BCE, each pixel in CAM may be responsive to multiple classes co-occurring in the same receptive field.

In this paper, we propose a novel approach called meta-transfer learning (MTL) which learns to transfer the weights of a deep NN for few-shot learning tasks.
