Neural Network regression on a time serie

by nba2020   Last Updated August 13, 2019 20:19 PM - source

I want to predict the trend values of a time serie [Y] based on the effect of other 10 input variables that can also have interaction. Since the combination of interaction is unknown, I am applying a regression NN to automatically detect and take that into account. The process I follow is:

  1. Get raw data of [Y] time serie per week

  2. Perfom decomposition and extract the [Y] Trend element per week

  3. Merge observations of the [Y] Trend with the observations of the 10 variables by week into a common table

  4. Normalize (min-max) all variables between 0 and 1

  5. Fit a NN model with Trend as 1 output node and the 10 variables as the input nodes.

  6. Perform k-fold cross validation

Am I following a logic approach or is it anything important that I'm missing?
