Data Augmentation of Contrastive Learning is Estimating Positive-incentive Noise

ICML 2026poster

Inspired by the idea of Positive-incentive Noise (*Pi-Noise* or *$\pi$-Noise*) that aims at learning the reliable noise beneficial to tasks, we scientifically investigate the connection between contrastive learning and $\pi$-noise in this paper. By converting the contrastive loss to an auxiliary Gau…

Rectified Noise: A Generative Model Using Positive-incentive Noise

AAAI 2026technical

Rectified Flow (RF) has been widely used as an effective generative model. Although RF is primarily based on probability flow Ordinary Differential Equations (ODE), recent studies have shown that injecting noise through reverse-time Stochastic Differential Equations (SDE) for sampling can achieve su

Why Does Dropping Edges Usually Outperform Adding Edges in Graph Contrastive Learning?

AAAI 2025technical

Graph contrastive learning (GCL) has been widely used as an effective self-supervised learning method for graph representation learning. However, how to apply adequate and stable graph augmentation to generating proper views for contrastive learning remains an essential problem. Dropping edges is a…
