Learning-to-RankML OrchestrationProduction MLRecommendation Systems

Overview

RankForge fills the critical gap between Learning-to-Rank (LTR) model libraries like XGBoost and LightGBM and production deployment. It provides a comprehensive orchestration layer with pluggable feature stores, replay-based backtesting, A/B test harness, and FastAPI serving with a consistent, model-agnostic interface.

Key Features

  • Model-Agnostic Interface: Works seamlessly with XGBoost, LightGBM, and other LTR libraries
  • Pluggable Feature Stores: Flexible integration with various feature store backends
  • Replay-Based Backtesting: Simulate historical scenarios for model validation
  • A/B Testing Framework: Built-in harness for production A/B testing
  • FastAPI Serving: High-performance REST API for model serving
  • Production-Ready: Designed for enterprise-scale deployments
