You can see in the following picture a demand problem.
My question relates to how one can/should implement fixed holidays in a LSTM model, which as seen here contain no demand and therefore cause sudden strong 1-day deviations from the average. I am specifically not referring to the change in trend between December and January
An Arima model, for example, can handle such days well.
After hours of searching the internet, all I could find was things how to deal with a change in trend. However, this is not the case, the trend remains the same and is only suspended for one day. I Hope there is someone here who has a paper or an approach for this kind of problem.
