Figure 1.
A diagram of strong data augmentation passing transformed inputs through f theta to produce representations that attract matching pairs and repel others.The diagram begins with original inputs, including x 1. Transformations t a and t b create x 1 a and x 1 b, alongside additional augmented inputs. These inputs pass through f theta to produce corresponding representations, including z 1 a and z 1 b. Arrows labelled attract connect z 1 a and z 1 b. Arrows labelled repel connect the other representations with the matching representations.

Contrastive learning is implemented with data augmentation and instance discrimination. x1a acts as an anchor
