Data-Driven Regularization Parameter Selection in Dynamic MRI [PDF]

open access: yesJournal of Imaging, 2021
In dynamic MRI, sufficient temporal resolution can often only be obtained using imaging protocols which produce undersampled data for each image in the time series. This has led to the popularity of compressed sensing (CS) based reconstructions.

Parameter Selection for Principal Curves [PDF]

open access: yesIEEE Transactions on Information Theory, 2012
Principal curves are nonlinear generalizations of the notion of first principal component. Roughly, a principal curve is a parameterized curve in R-d which passes through the "middle" of a data cloud drawn from some unknown probability distribution. Depending on the definition, a principal curve relies on some unknown parameters (number of segments ...
