Designing a Robust MLOps Pipeline for Real-Time Forecasting

MLOps Pipeline for Real-Time Forecasting Cover Image

Production forecasting systems operate in continuous tension with non-stationary environments. When customer behavior changes or macro-economic signals fluctuate, traditional static models degrade rapidly.

In this article, we break down an automated MLOps architecture capable of handling multi-horizon forecasting with continuous validation and automated rollback capabilities.

The Dual-Model Architecture

Rather than relying on a single monolithic predictor, our architecture decouples high-frequency baseline signals from long-horizon trend discovery:

  • XGBoost Layer: Ingests lag features, rolling statistics, calendar events, and holiday encodings.
  • LSTM / Temporal Fusion Layer: Ingests sequential embeddings to capture seasonal drift across extended horizons.

Automated Drift Detection & MLflow

Using MLflow, every training job logs validation loss curves, residual distributions, and feature importance matrices.

# Registering a candidate model to MLflow Model Registry

  --model-uri "runs:/d4e892c9b1/forecasting_engine" \
  --name "DemandForecasterProduction"

When Kolmogorov-Smirnov statistical tests indicate distribution divergence between incoming inference batches and training sets, the pipeline automatically flags the model for retraining.
