Window Rolling Mean (Moving Average) . https: //www.bing.com/ck/a this goal we are using standard deviation and Variance because it is the average degree which. B The biases and weights in the Network object are all initialized randomly, using the Numpy np.random.randn function to generate Gaussian distributions with mean $0$ and standard deviation $1$. I ran an ADF test and it told me my time series was stationary however, by having a rolling mean and rolling S.D on my differences series, despite ADF telling me its stationary I DONT have a constant rolling means or rolling S.D. This implementation compute the standard deviation for the neghibour . A rolling average can help you find trends that would otherwise be hard to detect.
