The LASSO risk: asymptotic results and real world examples
Coefficient vector linear observation construct sparse the lasso matrix sequence
2015/8/21
We consider the problem of learning a coefficient vector x0 ∈ RN from noisy linear observation y = Ax0 + w ∈ Rn. In many contexts (ranging from model
selection to image processing) it is desirable to...
Inflation in string theory: a graceful exit to the real world
Inflation in string theory the real world
2011/1/13
The most important criteria for a successful inflation are to explain the observed temperature anisotropy in the cosmic microwave background radiation, and exiting inflation in a vacuum where it can ...
Proof-of-Concept of Real-World Quantum Key Distribution with Quantum Frames
Proof-of-Concept Real-World Quantum Quantum Frames
2010/4/7
We propose and experimentally investigate a fibre-based quantum key distribution system, which employs polarization qubits encoded into faint laser pulses. As a novel feature, it allows sending of cla...
