Darts: Time Series Analysis made easy

Dart: Sci-kit learn for Time Series Analysis It comprises all the API required for Time series analysis and its primary goal is to simplify the time series machine learning experience. Darts in not inbuilt, so install it using " pip install u8darts" In [4]: import pandas as pd from darts import TimeSeries Like pandas has DataFrame, Similarly, Darts has TimeSeries In [7]: df = pd . read_csv ( '../input/air-passengers/AirPassengers.csv' ) Series = TimeSeries . from_dataframe ( df , 'Month' , '#Passengers' ) This timeseries is univariate, containing only one variable. Splitting the series into training and validation TimeSeries In [9]: train , val = Series . split_before ( pd . Timestamp ( '19580101' )) Models All the time series models: Exponential smoothing, ARIMA & auto-ARIMA, Facebook Prophet, Theta method, FFT (Fast Fourier Transform), Recurrent neural networks (vanilla RNNs, GRU, and LSTM variants), Temporal Convol...
