Time Series Forecasting With a Learning Algorithm : An Approximate Dynamic Programming Approach
Collado, Ricardo - 2019
We consider the basic problem of refi tting a time series over a finite period of time and formulate it as a stochastic dynamic program. By changing the underlying Markov decision process we are able to obtain a model that at optimality considers historical data as well as forecasts of future...
