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

Journal 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.

Projective light-sheet microscopy with flexible parameter selection [PDF]

Nature Communications
Projection imaging accelerates volumetric interrogation in fluorescence microscopy, but for multi-cellular samples, the resulting images may lack contrast, as many structures and haze are summed up.

Parameter Selection for Principal Curves [PDF]

IEEE 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 ...

LoRa Transmission Parameter Selection [PDF]

2017 13th International Conference on Distributed Computing in Sensor Systems (DCOSS), 2017
Low-Power Wide-Area Network (LPWAN) technologies such as Long Range (LoRa) are emerging that enable power efficient wireless communication over very long distances. LPWAN devices typically communicate directly to a sink node which removes the need of constructing and maintaining a complex multi-hop network.
