PCA++: How Uniformity Induces Robustness to Background Noise in Contrastive Learning
PCA++: How Uniformity Induces Robustness to Background Noise in Contrastive Learning arXiv:2511.12278v1 Announce Type: new Abstract: High-dimensional data often contain low-dimensional signals obscured by structured background noise, which limits the effectiveness of standard PCA. Motivated by contrastive learning, we address the problem of recovering shared signal subspaces from positive pairs, paired observations sharing the same…

Constraint-based causal discovery with tiered background knowledge and latent variables in single or overlapping datasets
Constraint-based causal discovery with tiered background knowledge and latent variables in single or overlapping datasets arXiv:2503.21526v1 Announce Type: new Abstract: In this paper we consider the use of tiered background knowledge within constraint based causal discovery. Our focus is on settings relaxing causal sufficiency, i.e. allowing for latent variables which may arise because relevant information…
