The students see math in everything. The obesity epidemic. The effects of second-hand smoke. Prison reform. Political ads.They ask: Can we model these populations? Can we reveal what factors make a di...
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...

Learning in A Changing World: Non-Bayesian Restless Multi-Armed Bandit
Non-Bayesian Multi-Armed Bandit
2010/11/24
We consider the restless multi-armed bandit (RMAB) problem with unknown dynamics. In this problem, at each time, a player chooses K out of N (N > K) arms to play. The state of each arm determines the ...
Nonlinear sigma models with non-compact target space and non-amen-able symmetry group were introduced long ago in the study of disordered electron systems. They also occur in dimensionally reduced qu...
A nonlinear small-world network model has been presented to investigate the effect of nonlinear interaction and time delay on the dynamic properties of small-world networks. Both numerical simulations...
Moment-Based Analysis of Synchronization in Small-World Networks of Oscillators
Synchronization Oscillators Small-World Networks
2010/4/2
In this paper, we investigate synchronization in a small-world network of coupled nonlinear oscillators. This network is constructed by introducing random shortcuts in a nearest-neighbors ring. The lo...
