High-performance Contextual Bandits and Reinforcement Learning using Vowpal Wabbit

🐍 Installation • 🚀 Features • 📚 Usage example • 📙 Documentation • 🔍 License

Sinapsis Vowpal Wabbit provides a modular framework for implementing real-time decision-making systems. By leveraging the industry-standard Vowpal Wabbit engine, this module enables efficient online learning and reinforcement learning (RL) workflows with minimal latency.

🐍 Installation

Install using your package manager of choice. We encourage the use of uv

Example with uv:

  uv pip install sinapsis-vowpal-wabbit --extra-index-url https://pypi.sinapsis.tech

or with raw pip:

  pip install sinapsis-vowpal-wabbit --extra-index-url https://pypi.sinapsis.tech

[!IMPORTANT] Templates may require extra dependencies. For development, we recommend installing the package with all the optional dependencies:

with uv:

  uv pip install sinapsis-vowpal-wabbit[all] --extra-index-url https://pypi.sinapsis.tech

or with raw pip:

  pip install sinapsis-vowpal-wabbit[all] --extra-index-url https://pypi.sinapsis.tech

[!TIP] Use CLI command sinapsis info --all-template-names to show a list with all the available Template names installed with Sinapsis OCR.

[!TIP] Use CLI command sinapsis info --example-template-config CBExploreADFPredict to produce an example Agent config for the CBExploreADFPredict template.

🚀 Features

Templates Supported

This repository implements specific templates for Vowpal Wabbit's most powerful reductions:

• CBExploreADFPredict: Handles real-time inference for Contextual Bandits using Action-Dependent Features (ADF).

• CBExploreADFLearn: Template to perform offline learning. It iterates through historical datasets (context, action, reward) for a defined number of epochs to optimize the model weights before deployment.

• CBExploreADFPredictEmbeddings: Handles real-time inference for Contextual Bandits using Action-Dependent Features (ADF) enhanced with text embeddings. This template processes incoming context and actions by combining traditional raw text features with vector-based embeddings to provide more nuanced, semantically aware predictions in production environments.

• CBExploreADFLearnEmbeddings: Template for offline learning that incorporates text embeddings into the optimization process. It iterates through historical datasets (context, actions, and rewards) over a defined number of epochs. By training on a combination of raw text and sentence based embeddings, it captures deeper semantic relationships to more effectively optimize model weights prior to deployment.
