TSMixer (Time-series Mixer) is an all-MLP architecture for time series forecasting. 2 Darts defaults to "both". 17. The basic data type in Darts is TimeSeries, which represents a multivariate (and possibly probabilistic) time series. If m is None, we work under the assumption that there is a unique seasonality period, which is inferred from the Auto-correlation Function (ACF). All the methods below return two list of TimeSeries: one list of training series and one list of “test” series (of length HORIZON). Default: None.
