functime-org / functime
Time-series machine learning at scale. Built with Polars for embarrassingly parallel feature extraction and forecasts on panel data.
Why this job: works in the areas we cover, but does not say which job it does
What it does
- Fast. Forecast and extract features (e.g. tsfresh, Catch22) across 100,000 time series in seconds *on your laptop*
- Efficient. Embarrassingly parallel feature engineering for time-series using Polars
- Battle-tested. Machine learning algorithms that deliver real business impact and win competitions
- Exogenous features. supported by every forecaster
- Backtesting with expanding window and sliding window splitters
