A recent paper published on arXiv introduces the concept of cellwise outliers in statistics and machine learning, distinguishing them from traditional casewise outliers. These cellwise outliers, which are individual values within a data matrix, can significantly impact analyses even when present in small proportions. The paper reviews advancements in handling these cellwise outliers, particularly for high-dimensional data, covering methods for location and covariance estimation, regression, and principal component analysis.
