New LCMC method improves categorical matrix completion

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called Latent Structural Categorical Matrix Completion (LCMC) to address the challenge of completing matrices with categorical data. LCMC utilizes a latent factorization approach by encoding categorical entries as one-hot vectors within a binary tensor representation. The framework includes an adaptive latent dimension estimation and tensor factorization, supported by theoretical analysis. Experiments on synthetic and real-world viral quasispecies data show LCMC outperforms existing methods in accuracy and efficiency. AI

    Latent Structural Categorical Matrix Completion with Application to Quasispecies Analysis

    arXiv:2606.08188v1 Announce Type: cross Abstract: Matrix completion has been extensively studied for real-valued data, but existing methods are often limited in handling categorical variables. We propose LCMC, a double-loop optimization framework for categorical matrix completion…
