A weak correlation dictionary construction method for sparse coding has been proposed in this paper. Firstly, a new dictionary atom initialization is proposed in which data samples with weak correlation are selected as the initial dictionary atoms in order to effectively reduce the correlation among ...
Here we tested eyeblink conditioning, finger tapping, and prism adaptation in 42 children and 44 adults and estimated the degree of correlation between the performance measures. The results show that performance on all three tasks improves with age in typically developing school-aged children. ...
1) weak correlation coefficient matrix 弱相关系数矩阵 1. The paper introduces the characteristics of theweak correlation coefficient matrixand makes attestation accordingly. 文章给出了弱相关系数矩阵的性质 ,并做了简明扼要的证 2) correlation coefficient matrix ...
In the vertebrate retina, we show that weak correlations between pairs of neurons coexist with strongly collective behavior in the responses of ten or more neurons. Surprisingly, we find that this collective behavior is described quantitatively by models that capture the observed pairwise correlations...
内容也还是“ABC”。也就是说,retain是指针拷贝,copy是内容拷贝。strong，weak用来修饰属性。strong用来修饰强引用的属性；@property(strong)SomeClass*aObject;对应原来的@property(retain)SomeClass*aObject;和@property(copy)SomeClass*aObject;weak用来修饰弱引用的属性；@property(weak)SomeClass*aObject...
When analyzing the correlation between income and happiness, a weak positive correlation is found. What does this imply? A. Higher income guarantees happiness. B. Happiness leads to higher income. C. There is a slight tendency for higher income to be associated with more happiness. D. Income ...
Risk factors in many consumption-based asset pricing models display statistically weak correlation with the returns being priced. Some GMM procedures used to test these models have low power to reject misspecified stochastic discount factors (SDFs) when the covariance matrix of the asset returns with ...
Localized Magnetic Moments in Dilute Metallic Alloys: Correlation Effects We discuss qualitatively the importance of the correlation energy in determining the ground state of a metal with an impurity atom. For a single, partly occupied impurity d-state orbital, the correlation energy acts to prevent ...
Summary This paper addresses the question of how to conduct inference on weakly identified coefficients in unstable econometric models. The weak correlations between the instruments and the relevant first-order condition are modelled as local to zero, and we focus on moderate parameter instabilities. ...
