Firstly, an initial output is obtained through the sigmoid layer, then the value is scaled to between −1 and 1 through tanh, and finally the output value of the LSTM is obtained by multiplying pairwise with th
Taken from “Time-series Extreme Event Forecasting with Neural Networks at Uber”. Time series data was scaled by normalizing observations per batch of samples and each input series was de-trended, but not deseasonalized. Neural networks are sensitive to unscaled data, therefore we normalize every...
combina 1.1. Motivation & contribution This work shall be driven by an imperative need of healthcare systems to improve both patient safety and the security of patient data by means of enabling effective real-time anomaly detection. The current healthcare monitoring frameworks have deficiencies in t...

The traditional direct interpolation method is to bring the overall data into the inter- polation algorithm so as to fit a smooth and complete time-displacement curve, and the interpolation value corresponding to any time can be obtained in the curve. However, due to the different effects of ...
