Title: Tensor Completion Algorithms in Big Data Analytics,
Abstract: Tensor completion is a problem of filling the missing or unobserved entries
of partially observed tensors. Due to the multidimensional character of tensors
in describing complex datasets, tensor completion algorithms and their
applications have received wide attention and achievement in areas like data
mining, computer vision, signal processing, and neuroscience. In this survey,
we provide a modern overview of recent advances in tensor completion algorithms
from the perspective of big data analytics characterized by diverse variety,
large volume, and high velocity. We characterize these advances from four
perspectives: general tensor completion algorithms, tensor completion with
auxiliary information (variety), scalable tensor completion algorithms
(volume), and dynamic tensor completion algorithms (velocity). Further, we
identify several tensor completion applications on real-world data-driven
problems and present some common experimental frameworks popularized in the
literature. Our goal is to summarize these popular methods and introduce them
to researchers and practitioners for promoting future research and
applications. We conclude with a discussion of key challenges and promising
research directions in this community for future exploration.
