A Practical Guide to Wavelet Analysis
paos.colorado.eduedge effects due to finite-length time se-ries, the relationship between wavelet scale and Fourier period, and time series reconstruction. Section 4 presents the theoretical wavelet spectra for both white-noise and red-noise processes. These theoretical spectra are compared to Monte Carlo results and are used to es-tablish significance levels ...
Machine Learning Applied to Weather Forecasting
cs229.stanford.eduDec 15, 2016 · Since weather forecasting inherently involves time se-ries, k-fold cross-validation is a poor technique to analyze whether our model will generalize to an independent test set. Instead, a 4-fold forward chaining time-series cross validation was performed, wherein the test set consisted of the data from the year immediately following the train-
Time-Aware Multi-Scale RNNs for Time Series Modeling

Meanwhile, the temporal context information is used to select the most impor-tant scale at each time step adaptively, capturing more com-plicated temporal patterns.
