  "Description": "Tensor Factor Models (TFM) are appealing dimension\nreduction tools for high-order tensor time series, and have\nwide applications in economics, finance and medical imaging. We\npropose an one-step projection estimator by minimizing the\nleast-square loss function, and further propose a robust\nestimator with an iterative weighted projection technique by\nutilizing the Huber loss function. The methods are discussed in\nBarigozzi et al. (2022) <arXiv:2206.09800>, and Barigozzi et\nal. (2023) <arXiv:2303.18163>.",
