Rethinking Samples Selection for Contrastive Learning: Mining of Potential Samples

no code implementations1 Nov 2023 Hengkui Dong, Xianzhong Long, Yun Li

Contrastive learning predicts whether two images belong to the same category by training a model to make their feature representations as close or as far away as possible.

MNN: Mixed Nearest-Neighbors for Self-Supervised Learning

1 code implementation1 Nov 2023 Xianzhong Long, Chen Peng, Yun Li

In contrastive self-supervised learning, positive samples are typically drawn from the same image but in different augmented views, resulting in a relatively limited source of positive samples.
