Fig. 7From: A electricity theft detection method through contrastive learning in smart gridThe visualization of contrastive representation learning: the left is a training ratio of 60%, and on the right is a training ratio of 80%. In the heat map, the numbers on the left and bottom represent categories: 0 indicates normal users, and 1 indicates abnormal users. The lighter the color is, the higher the similarity would be. A similarity of 1 means this is the same vectorBack to article page
