Data is the new oil and its size is growing exponentially day by day. Most of the companies are leveraging data science capabilities extensively to affect business decisions, perform audits on ML patterns, decode faults in business logic, and more. They run large number of machine learning model to produce results.

Managing ML models in production is non-trivial. The training, maintenance, deployment, monitoring, organization and documentation of machine learning (ML) models – in short model management – is a critical task in virtually all production ML use cases. Wrong model management decisions can lead to poor performance of a ML system and can result in high maintenance cost and less effective utilization. Below are the key concern for model management:

Computational challenges: machine learning model definition and validation, decisions on model retraining, adversarial settings.
Data management challenges: lack of a declarative abstraction for the whole ML pipeline, querying model metadata, model interpretation.
Engineering challenges: multiple tools and frameworks make integration complex, heterogeneous skill level of users, backwards compatibility of trained Models and hard to reproduce the training result.

~From Ravi Ranjan’s proposal:


  • Managing ML models in production is non-trivial. What are the challenges and concerns of machine learning management lifecycle?
  • What is machine learning model management?


Basic understating of machine learning and its workflow

    • Data lineage is important for training models: Training and Validation data need to be isolated and tracable on models trained
    • Performance of models to be compared for model understanding and promotion
    • Reproducability of operations: training, serving and validation become important
    • Compliance and Audit requirements for sensitive industries like Healthcare and Finance
    • Tooling and transparent components in architecture for better integrated workflows in model management
