  "Description": "The matrix factor model has drawn growing attention for\nits advantage in achieving two-directional dimension reduction\nsimultaneously for matrix-structured observations. In contrast\nto the Principal Component Analysis (PCA)-based methods, we\npropose a simple Iterative Alternating Least Squares (IALS)\nalgorithm for matrix factor model, see the details in He et al.\n(2023) <arXiv:2301.00360>.",
