What algorithm does Prophet use?

Prophet is an additive regression model with a piecewise linear or logistic growth curve trend . It includes a yearly seasonal component modeled using Fourier series and a weekly seasonal component modeled using dummy variables. For more information, see Prophet: forecasting at scale .

Python predict() function enables us to predict the labels of the data values on the basis of the trained model. The predict() function accepts only a single argument which is usually the data to be tested.
