In our previous article, "5 Challenges to be Prepared for While Scaling ML Models," we delved into the top five hurdles in productionizing scalable Machine Learning models. Now, our focus shifts to establishing best practices for successfully deploying ML models in production.

The Importance of Productionizing ML Models

Machine Learning models today address a myriad of specific business challenges across various industries. Countless examples abound of machine learning model deployments effectively solving business use cases. In this piece, however, we aim to explore an approach to building ML models that are readily deployable into production environments.

To commence, it's imperative to eliminate the right risks early in the production process. Addressing a higher number of risks during the model selection and development phases minimizes rework during productionization.

Challenges in Productionizing ML Models

According to Sigmoid's pre-webinar poll, 43% of companies find ML productionization and integration challenging. This underscores the importance of establishing robust practices for deploying ML models effectively.

Best Practices for Successful ML Model Deployment

Data Assessment: Begin by assessing data feasibility. Do we possess the requisite datasets to run ML models effectively? Is data acquisition sufficiently prompt for predictions? For instance, restaurant chains often have access to extensive customer data, providing a rich source for ML model execution. Once data risks are mitigated, setting up a data lake environment streamlines access to diverse data sources, eliminating bureaucratic hurdles. Experimentation with datasets to ensure their adequacy for driving desired business outcomes is crucial. Additionally, implementing scalable computing environments expedites data processing.

Evaluation of the Right Tech Stack: Upon selecting ML models, manual testing validates their efficacy. For instance, in personalized email marketing, assessing whether promotional emails drive new conversions informs strategy refinement. Once manual tests yield success, selecting the right technology stack is imperative. Data science teams should have flexibility in choosing from a range of technology stacks to facilitate experimentation and streamline ML productionization.

Robust Deployment Approach: Standardizing the deployment process facilitates seamless testing, integration, and training of ML models at various junctures. Data engineers should focus on refining the codebase, integrating the model (e.g., as an API endpoint), and implementing workflow automation to streamline integration. A conducive environment with access to requisite datasets and models is pivotal for ML model success.

Post-Deployment Support & Testing: Implementing frameworks for logging, monitoring, and reporting results simplifies the testing process. Real-time testing and close monitoring ensure stability. In a sophisticated experimentation system, test results inform ML model training at scale. Vigilance for negative or erroneous results is vital, with adherence to service level agreements (SLAs) and close monitoring of data quality and model performance.

Change Management & Communication: Clear communication between cross-functional teams is paramount for ML model success. Collaboration between data engineering and data science teams is essential for deploying ML models into production. Data scientists should have full visibility into the system to inspect code and review production results. Transparent communication streamlines efforts and saves time.

Conclusion

In addition to implementing the aforementioned best practices, ML models should be designed for reusability and resilience to changes and unforeseen events. The goal is not necessarily to have all recommended methods in place but to ensure specific areas are mature enough and scalable to meet evolving business requirements. Effective calibration of these practices ensures adaptability to changing needs over time, fostering successful ML model deployment in production environments.
