Functime

Functime is an automated machine learning (AutoML) tool designed specifically for business forecasting. It has the capability to forecast, backtest, and score 100,000 time series in under 10 seconds. It incorporates various types of data sources and uses advanced techniques such as quantile regression and conformal prediction for forecasting. Functime also offers GPT-4-enabled trend-seasonality analysis and powerful visualization capabilities using ECharts and Plotly libraries.

Functime's unique speed is due to its purpose-built design for fast execution and efficient memory usage. It can forecast, backtest, and score 100,000 time series in under 10 seconds, which is 100 times faster than other tools like Amazon Forecast and u8darts. Additionally, Functime uses 20 times less memory as compared to other solutions.

Functime integrates external data by supporting exogenous features and causal analysis. Users can add these features either from API integrations or from their own datasets. This feature allows for a more thorough and relevant analysis by taking into account external factors.

Functime allows the integration of various types of external data including holiday, weather, economic, and other relevant external data sources. This provides a more in-depth analysis that goes beyond analyzing numerical trends and includes factors that could have a causal impact.

Feature importance plots in Functime help in interpreting each forecast. The feature importance plot shows the contribution of each feature to the forecast. This aids in understanding which features are important and how they are contributing to the overall forecast.
