We consider the functional linear regression model with a scalar response and a Hilbert space-valued predictor, a well-known ill-posed inverse problem. We propose a new formulation of the functional partial least-squares (PLS) estimator related to th

In this paper, we develop new methods for analyzing high-dimensional tensor datasets. A tensor factor model describes a high-dimensional dataset as a sum of a low-rank component and an idiosyncratic noise, generalizing traditional factor models for p

Background. Morphological changes in the esophageal mucosa (EM) depend on the type of esophageal achalasia (ЕA). In types I and II of ЕA, morphological changes are subtle, but in types III and IV, dystrophic changes are clearly visible. ЕA can tra
