Soothsayer is an Elixir library for time series forecasting, inspired by Facebook’s Prophet and NeuralProphet. It provides a flexible and easy-to-use interface for creating and training forecasting models.

It’s a neural network but it focuses on understandability and explainability, useful when you need to present the model output to human review.

Launched at ElixirConf US 2024 in Orlando.

There’s lots of features missing from NeuralProphet (check the README). I’ll be implementing them, but if you are interested in anything, let me know.
