Representation learning objectives yield distinct latent structures in psychometric data

A new research paper explores how different representation learning objectives can uncover distinct latent structures within the same psychometric data. The study utilized data from 757 teacher-child pairs in the Cyprus ProW preschool trial, analyzing responses from the child SDQ, ASBI, and CBRS. Results showed that a contrastive objective significantly improved teacher-child retrieval accuracy compared to principal component analysis (PCA)-based representations, but PCA-based methods better preserved the underlying behavioral phenotype structure. A multi-task objective offered a partial restoration of behavioral organization at the cost of retrieval performance, indicating that correspondence and phenotype structure represent separate latent organizations.
