The paper introduces Coupled Tensor‑Tensor Completion (CTTC), a new framework that incorporates side information in tensor form to enhance tensor completion tasks. CTTC leverages hidden connections among multimodal tensors and is grounded in distance metric learning and group theory. Experiments on the DTD and LINCS datasets show that CTTC outperforms existing methods such as HaLRTC, CTRC, Cell, and NTDDR in both run‑time and root‑sum‑of‑errors accuracy for predicting drug effects.

The paper introduces an unsupervised machine learning framework that fuses heterogeneous genomic and clinical data using tensor decomposition and clustering to predict cancer risk levels. By extracting latent, biologically meaningful features through tensor decomposition, the approach outperforms unimodal feature sets. Experiments on LinkedOmics data of 11,158 patients across 32 cancer types show that the tSVD+GMM configuration consistently achieves superior performance on clinical benchmarks such as tumor purity, pathological stage, and survival outcomes.

Tensor Completion using Subspace Information (TCSI) is an algorithm that leverages side information by estimating a subspace and reformulating tensor completion as a matrix regression problem. Theoretical analysis shows that accurate subspace information reduces sample complexity to nearly linear in the uncoupled ambient dimensions and relaxes signal-to-noise ratio requirements compared to existing guarantees. Numerical simulations and an application to reconstructing global Total Electron Content (TEC) maps demonstrate lower reconstruction errors than competing methods.
