Ludwig is a declarative machine learning framework that builds and trains end-to-end models from data-driven configuration files, without requiring users to write model code.
Ludwig is an open-source, declarative machine learning framework designed to let users build and deploy end-to-end ML pipelines without writing custom model code. Its primary purpose is to make model development accessible and consistent by defining models, training, and evaluation entirely through configuration files driven by the structure of the data. This approach enables faster experimentation and reproducible workflows across teams and projects.
At its core, Ludwig uses data-driven configurations to automatically infer appropriate encoders, decoders, and training procedures for a wide range of data types, including text, images, tabular, time series, and categorical data. It supports model training, hyperparameter optimization, evaluation, and prediction through simple CLI commands or Python APIs, reducing boilerplate and implementation details. Ludwig integrates with popular deep learning backends and supports distributed and scalable training, making it suitable for both prototyping and production workloads. Built-in visualization and analysis tools help users inspect model performance, feature importance, and error patterns to refine their models.
