Designing a Robust MLOps Pipeline for Real-Time Forecasting
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.

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