Understanding MLOps and Model Governance
MLOps encompasses model governance, ensuring machine learning models at scale are reliable and meet all business requirements. Effective, straightforward model governance tactics are essential in achieving this. ML model governance is responsible for constructing, training, versioning, and disbursing machine learning models.
The Role of Experiments in Model Development
When developing new machine learning models or using them in new areas, a multitude of experiments using different aspects such as optimizers, model infrastructures, loss functions, variables, parameters, and inputs are carried out by professionals in the field. These experiments serve to discover the perfect model setup. Lacking a mechanism to oversee model configurations and performance during tests could result in chaos, as it may become hard to discern and choose the optimal solution. Keeping track of all trials and results can be a daunting task even for a dedicated researcher working independently.
Importance of Model Management
Hence, model management is critical. It empowers individuals, teams, and businesses to take a preemptive approach to common organizational hurdles, have an improved way of tracking data, code, metrics, and model versioning for reproducible experiments, package and deliver models in standard configurations for easier reuse, and assist in testing, CI/CD, and monitoring.
Components of the ML Model Management System
Components of the ML Model Management system include:
- Version Control Systems for aiding ML model development in supervising changes to the source code.
- Data Version Management for overseeing model modifications in relation to datasets.
- Code Checkpointing for addressing changes to the model's source code.
- Experiment Locator for monitoring, gathering, and organizing model training/validation data/performance across multiple runs with different configurations and datasets.
- Model Registry for comprehensive oversight of ML models that have been trained, staged, and deployed.
- Model Observation for keeping up on the model's inference performance and deter any signs of Serving Skew.
Significance and Benefits
The significance of ML Model Management in the machine learning workflow cannot be overstated. It simplifies the management of the ML model lifecycle from creation to deployment, including configuration, experimentation, and tracking of multiple experiments.
Model Management takes into account two key aspects: Models (where packaging, deployment strategies, monitoring, and retraining occur) and Experiments (which deals with loss & training metrics, graphics, text, other vital pieces of information, and versioning of pipelines, data, and code).
For data teams, effective model management makes the process of creating, monitoring, comparing, deploying, and replicating models less challenging. On the other hand, casual approaches can result in ML projects that lack repeatability, sustainability, scalability, and coordination.
Benefits of model management include:
- Establishing a centralized information source.
- Enabling model versioning for standards and consistency.
- Making mitigation of issues (underfitting, overfitting, bias, or performance) easier.
- Enhancing traceability and legal compliance.
- Accelerating research and development.
- Boosting team productivity and clarity of objectives.
- Fostering collaboration around code, data, and documentation through the use of various best practices and technologies.
