Weighted least square ensemble networks
Ensemble of networks has been proven to give better prediction result than a single network. Two commonly used way of determining the ensemble weights are simple average ensemble method and the generalized ensemble method. In the paper, we propose the weighted least square ensemble network. The major difference between this method and the other ensemble methods is that we do not assume that nei...

متن کاملThe least square method in the determination of thermal diffusivity using a flash method
2014 This paper is devoted to the description of a fitting method of experimental data for the model of Parker et al. [1] used in thermal diffusivity measurements by a laser flash method. The presented method is adapted to the fitting case when the noise frequencies are in the spectral band of the transient signal, thus making the filtering by a low-pass band filter difficult if not impossible....
متن کاملR2* Measurement Using Absolute SNR-Weighted Least Square Regression
INTRODUCTION Accurate R2* measurements are critical for many quantitative imaging applications. R2* is estimated via mono-exponential fitting of signal decay within a series of gradient echo (GRE) images sampled at increasing TE. Root-sum-of-square (RSS) remains the most common approach to combine surface coil array images at each TE prior to the data fitting procedure. Rapid signal decay can r...
متن کاملA Note on Change Point Detection Using Weighted Least Square
This paper is concerned with the application of weighted least square method in change point analysis. Testing shift in the mean normal observations with time varying variances as well as of a GARCH time series are considered. For both cases, the weighted estimators are given and their asymptotic behaviors are studied. It is also described that how the resampling methods like Monte Carlo and bo...
