Another consequence of the definition given above is that the support of a continuous random variable must be uncountable. In fact, by the previous property, if the support (the set of values the variable can take) was countable, then we would have which is a contradiction because the probabi...

It quantifies the total information of one random variable gotten by another random variable. This can be summarized as I(X;Z) = \int_{\mathcal{X} \times \mathcal{Z}} \log \frac{d\mathbb{P}_{XZ}}{d\mathbb{P}_X \otimes \mathbb{P}_Z} d \mathbb{P}_{XZ}, where \mathbb{...
We consider a time series model which is a first-order autoregressive process plus a random error. With variable intervals, the sampling time may be inconvenient, so using only two intervals, referred to as variable sampling interval at fix times makes the method easier to use in practice. ...

and therefore an IV will typically not be associated with factors that confound the association of exposure and outcome. Examples of non-genetic instrumental variables include external factors which influence a population largely at random, such as the famine experienced in the Dutch Hunger Winter[39...
The ideas of variable sampling interval (VSI), variable sample size (VSS), variable sample size and sampling interval (VSSI), and variable parameters (VP) in the univariate case have been successfully applied to the multivariate case to improve the efficiency of Hotelling’s T2 chart with fixed...

TensorFlow中的变量一般就是模型的参数。当模型复杂的时候共享变量会无比复杂。 官网给了一个case,当创建两层卷积的过滤器时,每输入一次图片就会创建一次过滤器对应的变量,但是我们希望所有图片都共享同一过滤器变量,一共有4个变量:conv1_weights,conv1_biases,conv2_weights, and conv2_biases。
