2016/5/24
Pen gesture interfaces have difficulty supporting arbitrary
multiple-stroke selections because lifting the pen introduces
ambiguity as to whether the next stroke should add to the existing
selectio...
Generalized Selection via Interactive Query Relaxation
Selection annotation pointing reference information visualization input techniques query relaxation
2016/5/24
Selection is a fundamental task in interactive applications,
typically performed by clicking or lassoing items of
interest. However, users may require more nuanced forms
of selection. Selecting reg...
Spatial Weights Matrix Selection and Model Averaging for Spatial Autoregressive Models
Model Selection Model Averaging Spatial Econometrics Spatial Autoregressive
2016/1/26
Spatial econometrics relies on spatial weights matrix to specify the cross sectional depen-dence, which might not be unique. This paper proposes a model selection procedure to choose an optimal weight...
Band Width Selection for High Dimensional Covariance Matrix Estimation
Bandable covariance Banding estimator Large p, small n Ratio- consistency Tapering estimator Thresholding estimator
2016/1/25
The banding estimator of Bickel and Levina (2008a) and its tapering version of Cai, Zhang and Zhou (2010), are important high dimensional covariance esti-mators. Both estimators require choosing a ban...
Multivariate Regression Shrinkage and Selection by Canonical Correlation Analysis
Adaptive Lasso Canonical Correlation Analysis Multivariate Regression
2016/1/25
The problem of regression shrinkage and selection for multivariate regression is considered. The goal is to consistently identify those variables relevant for regression. This is done not only for pre...
Delay-Aware Predictive Network Selection in Data Offloading
Delay-Aware Predictive Network Selection Data Offloading
2016/1/22
We tackle the network selection problem in operator-initiated mobile data offloading by considering both the predictive and non-predictive cases. For the non predictive case, we use the Lyapunov optim...
