    We likely overestimate AI's short-term impact, and there might even be a financial bubble about to pop. But I also think we underestimate the long-term impact. We're building absol…

    > Python had nothing comparable This is in part why we built Darts. Now I think we can say the situation is quite different. Darts offers many things offered by the R forecast pack…

    I would recommend Darts in Python [1]. It's easy to use (think fit()/predict()) and includes * Statistical models (ETS, (V)ARIMA(X), etc) * ML models (sklearn models, LGBM, etc) * …

    You can try installing it using pip install 'u8darts[torch]' This will give you everything besides Prophet and pmdarima.

    I would say that compared to Greykite, Darts really attempts to unify a wide variety of forecasting models under a common simple and user-friendly API. There are many differences, …

    In short: yes, at least anomaly detection. That's one of the main things on our to-do list.

    We do have ensemble models. Something like model = NaiveEnsembleModel([model1, model2, ...]) model.fit(my_series) prediction = model.predict() Will return an average prediction. Lo…

    Thanks for the feedback, I absolutely agree about the need for easy-to-use tools for dealing with time series. This is exactly the motivation that prompted us to work on Darts init…

    In some cases Darts is wrapping around existing models (like Prophet, or statsmodels-based models for instance); in other cases we wrote our own implementations, so it's really a m…

    Hi! I'm one core developer (and creator) of the library. Thanks for all the comments. I just wanted to highlight a couple of things that we think are quite cool about Darts: * It m…

    This is supported but only by neural-nets models, which are fit using SGD, hence naturally not requiring the whole dataset in memory. Other models like ARIMA do need the full serie…
