Patterns and Anti-Patterns for Memorializing Data Science Project ArtifactsSummit 2020

Data science projects involve a variety of artifacts that could potentially be memorialized, versioned, or transitioned to new owners: data sets, ETL code, exploratory analyses and visualizations, experiment configurations, modeling code, and serialized models (among other things). This talk presents a set of principles for organizing these artifacts such that - Project work is reproducible and easily transferred from one data scientist to another, - Important modeling and ETL decisions are recorded and explained, - Code organization is transparent and supports review practices, - The needs of production deployment are anticipated, - In the long term, the data science process is accelerated. Many of these principles are aligned with the design of particular toolchains for data science, such as MLflow, but all can be implemented using widely-used open-source tooling. Included in this presentation will be:

  • Options for storing or referencing modeling datasets and other artifacts
  • Treatment of PII and other sensitive information in project organization
  • Common anti-patterns for data science project organization, and their consequences
