Researchers have introduced Anchor PCA, a novel method for unsupervised dimension reduction in multi-domain datasets. This technique aims to find a robust shared embedding by focusing on common directions of variation, rather than pooling data which can be skewed by domain-specific noise. Anchor PCA offers a trade-off between overall explained variance and the agreement between shared and domain-specific embeddings, demonstrating improved performance on unseen data compared to traditional methods.
