I have a Time series data for almost 5 years. Using this data I want to forecast next 2 years. How to do this?
I referred many websites regarding this. I noticed that mostly predictions are done only with same set of data used for training they are not forecasting for future such as for next 30 days. If it possible to achieve this via TensorFlow. May I know how to achieve this?
