Degrees of freedom LARS algorithm lasso model selection SURE unbiased estimate
2015/8/21
We study the effective degrees of freedom of the lasso in the framework of Stein’s unbiased risk estimation (SURE). We show that the number of nonzero coefficients is an unbiased estimate for the degr...
"Quantization" of higher hamiltonian analogues of the Painleve I and Painleve II equations with two degrees of freedom

2012/4/27
We construct a solution of an analog of the Schr\"{o}dinger equation for the Hamiltonian $ H_I (z, t, q_1, q_2, p_1, p_2) $ corresponding to the second equation $P_1^2$ in the Painleve I hierarchy. Th...

2010/12/24
We study the thermodynamic properties of horizons using the dynamical description of the gravitational degrees of freedom at a horizon derived in an earlier work. We use the action of the horizon degr...

Spin Degrees Second Landau Level
2010/11/23
The spin degree of freedom in quantum phases of the second Landau level is probed by resonant light scattering.The long wavelength spin wave mode, which monitors the degree of spin polarization, is at...
Comments on Degrees of freedom region for $K$-user interference channel with $M$ antennas
Degrees of freedom region interference channel
2010/11/22
For a $K$-user interference channel with $M$ antenna at each transmitter and each receiver, the maximum total DoF of this channel has been previously determined to be $\max \sum_{k=1}^K d_k = MK/2$. H...

2010/11/10
We shall use symmetry breaking as a tool to attack the problem of identifying the topology of chaotic scatteruing with more then two degrees of freedom. specifically we discuss the structure of the ho...
