FbFa

FbFa is a term used in discussions of forecasting frameworks to denote a modular, feature-driven approach to time series forecasting and analysis. It is not tied to a single software product but to a design philosophy in which forecasting pipelines are built from interchangeable components.

FbFa stands for Feature-Based Forecasting Architecture (though variations of the idea are described under related terms). In this view, a forecasting system comprises a data ingestion layer, a feature library, a modeling engine or model zoo, an evaluation and backtesting module, and a deployment and monitoring component. The feature library provides systematically engineered predictors derived from raw data, enabling consistent experimentation and reuse across projects.

Applications are described across finance, energy, retail, and operations analytics, with an emphasis on rapid prototyping, reproducibility, and governance of predictive models. Proponents argue that FbFa-like designs improve collaboration between data scientists and domain experts because features can be shared and audited.

Adoption is heterogeneous; there is no single canonical FbFa implementation. Instead, multiple open-source and commercial platforms incorporate similar principles under different names. Critics note that the lack of universal standards can hinder interoperability and that added abstraction may introduce overhead for small teams.

Overall, FbFa describes a principled approach to structuring forecasting workflows around features, modular components, and rigorous evaluation. It is related to topics such as forecasting, feature engineering, and modular software design.
