We compare the convergence behavior of ADMM (alternating direction method of multipliers), [F]ISTA ([fast] iterative shrinkage and thresholding algorithm) and CD (coordinate descent) methods on the model `1-regularized least squares problem (aka LASSO). We use an eigenanalysis of the operators to compare their local convergence rates when close to the solution. We find that, when applicable, CD...

An extension for classi cation methods in order to process time-dependent data is introduced. It is based on the detection of transitions from one steady state to another one by examination of the time derivatives of classi cation vectors. The method is called Early Transition Detection. It is shown that it can be used in conjunction with a number of common classi cation methods like SIMCA or A...

The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the u...

Hardy plants can maintain their normal physiological metabolism in cold winter and against the cold weather by regulating themselves. Around this natural phenomenon, a large number of researchers conducted researches on cold resistance of hardy plants and the mechanism of cold resistance respectively from the point of cell membrane structure and characteristics, physiological metabolism, growth...

Geocoding, the process of matching addresses to geographic coordinates, is a necessary first step when using geographical information systems (GIS) technology. However, different geocoding methodologies can result in different geographic coordinates. The objective of this study was to compare the positional (i.e. longitude/latitude) difference between two common geocoding methods, i.e. ArcGIS (...

■ Abstract This paper presents a critical assessment of the field of common property. After discussing briefly the major findings and accomplishments of the scholarship on the commons, the paper pursues two strategies of critique. The first strategy of friendly critique accepts the basic assumptions of most writings on common property to show that scholars of commons have discovered far more va...
