Abstract
En 中文
Recent matrix completion based methods have not been able to properly model the haplotype assembly problem for noisy observations. To deal with such cases, we propose a new minimum error correction (MEC) based matrix completion problem over the manifold of rank-one matrices. We then prove the convergence of a specific iterative algorithm to solve this problem. From the simulation results, the proposed method not only outperforms some well-known matrix completion based methods, but also shows a more accurate result compared to a most recent MEC-based algorithm for haplotype estimation.
