A Geometric View on Constrained M-Estimators
Volkan Cevher, Yen-Huan Li, Ya-Ping Hsieh, Nissim Zerbib
We study the estimation error of constrained M-estimators, and derive explicit upper bounds on the expected estimation error determined by the Gaussian width of the constraint set. Both of the cases where the true parameter is on the boundary of the constr ...
2015What's the Frequency, Kenneth?: Sublinear Fourier Sampling Off the Grid
We design a sublinear Fourier sampling algorithm for a case of sparse off-grid frequency recovery. These are signals with the form ; i.e., exponential polynomials with a noise term. The frequencies satisfy and for some . We design a sublinear time randomiz ...
Springer Verlag2015Composite convex minimization involving self-concordant-like cost functions
Volkan Cevher, Quoc Tran Dinh, Yen-Huan Li
Abstract. The self-concordant-like property of a smooth convex func- tion is a new analytical structure that generalizes the self-concordant notion. While a wide variety of important applications feature the self- concordant-like property, this concept has ...
2015What’s the Frequency, Kenneth?: Sublinear Fourier Sampling Off the Grid
We design a sublinear Fourier sampling algorithm for a case of sparse off-grid frequency recovery. These are signals with the form f(t)=∑kj=1ajeiωjt+ν^ , t∈Z ; i.e., exponential polynomials with a noise term. The frequencies {ω j } satisfy ω j ∈ [η,2π − η ...
Springer Verlag2015Sparsistency of $\ell_1$-Regularized $M$-Estimators
Volkan Cevher, Jonathan Mark Scarlett, Yen-Huan Li
We consider the model selection consistency or sparsistency of a broad set of -regularized -estimators for linear and non-linear statistical models in a unified fashion. For this purpose, we propose the local structured smoothness condition (LSS ...
2015Consistency of $\ell_1$-Regularized Maximum-Likelihood for Compressive Poisson Regression
We consider Poisson regression with the canonical link function. This regression model is widely used in regression analysis involving count data; one important application in electrical engineering is transmission tomography. In this paper, we establish t ...
2015High-efficiency and stable quasi-solid-state dye-sensitized solar cell based on low molecular mass organogelator electrolyte
Michael Graetzel, Mohammad Khaja Nazeeruddin, Yong Ding, Bing Zhang, Lu Wang, Yen-Huan Li, Li Tao, Xu Pan
The highest photoelectric conversion efficiency (9.61%) for a quasi-solid-state DSSC (QS-DSSC) based on a low molecular mass organogelator (LMOG) is achieved using N, N'-1,5-pentanediylbis-dodecanamide as a LMOG in conjunction with a TiO2 photoanode of sub ...
Royal Soc Chemistry2015Barrier Smoothing for Nonsmooth Convex Minimization
Volkan Cevher, Quoc Tran Dinh, Yen-Huan Li
This paper proposes a smoothing technique for nonsmooth convex minimization using self-concordant barriers. To illustrate the main ideas, we compare our technique and the proximity smoothing approach (Nesterov2005) via the classical gradient method on both ...
