The Degrees of Freedom of Partly Smooth Regularizers
In this paper, we are concerned with regularized regression problems where the prior regularizer is a proper lower semicontinuous and convex function which is also partly smooth relative to a Riemannian submanifold. This encompasses as special cases several known penalties such as the Lasso (`-norm), the group Lasso (`−`-norm), the `∞-norm, and the nuclear norm. This also includes so-called ana...
متن کاملInvestigation of Freedom-Degrees impact on Modulation of Radiation
Introduction: Nowadays tendency to apply more degrees of freedom in high-tech radiotherapy systems, and consequent complex process to optimize dose calculation and delivery algorithms, is a challenge of radiation therapy optimization. Faster MLC speed, dose rate, Gantry angle variation, and other degrees, which have been utilized in IMRT, IMAT, VMAT, improved modulation of inte...
متن کاملUsing the Matrix Method to Compute the Degrees of Freedom of Mechanisms
In this paper, some definitions and traditional formulas for calculating the mobility of mechanisms are represented, e.g. Grubler formula, Somov - Malyshev formula, and Buchsbaum - Freudenstei. It is discussed that there are certain cases in which they are too ambiguous and incorrect to use. However, a matrix method is suggested based on the rank of the Jacobian of the mechanism and its applica...
متن کاملHadronic Degrees of Freedom
The point of view I take to summarize some of the research activities in Italy in the field of hadronic physics, is determined by the (today accepted) fundamental degrees of freedom of the strong interactions, namely quarks and gluons. The Sec. 2 is devoted to the link of the fundamental theory of strong interactions, Quantum Chromodynamics (QCD), with effective degrees of freedom often used to...
متن کاملFew degrees of freedom
The climate change conference in Copenhagen last month went to the wire with no agreement emerging until late on the last day. Ahead of the meeting, President Obama was expected to make a significant financial commitment to a global climate protection fund rather than improve on his provisional offer of cutting emissions by 4 per cent on 990 levels by 2020. The final accord declared deep cuts i...
