In this paper, we discuss new formulations of both redundancy analysis (RA) and partial least squares regression (PLS) which clearly show the connection between these two methods. These new formulations also show that RA and PLS regression are the two end points of a continuum approach that we propose to investigate. Moreover, it enjoys very interesting properties which highlight the rational o...

To promote the adoption of PHR system, understanding the factors that affect patients’ adoption of PHR system is of necessity. Based on previous research, this paper tries to develop a model to explore those elements that influence the behavior intentions of patients from the perspective of consumers.

A reason for these inconsistent results may be unobserved het...

This work presents an empirical modeling approach combining a bilinear modeling technique, Partial Least Squares, with the universal function approximation abilities of single hidden layer non-linear artificial neural networks. This approach, referred to as Neural Network Partial Least Squares, is compared to the common Autoassociative Artificial Neural Network. The Neural Network Partial Least...
