5 stops · basics first
  1. Dataset ✓ understood

    A collection of data examples used for training, validating, or testing machine learning models.

  2. Training ✓ understood

    The process of fitting a model to data by repeatedly measuring how wrong its outputs are and adjusting its parameters to reduce that error.

  3. Inference ✓ understood

    Running a trained model on new inputs to get predictions, with its weights frozen: the stage of a model's life that users actually interact with.

  4. Data Drift ✓ understood

    Changes in input data distribution over time that can degrade model performance in production.

  5. Model Drift ✓ understood

    Degradation of model performance over time due to changes in the relationship between features and target.

  6. Model Performance Degradation · you are here ✓ understood

Decline in model quality over time due to distribution shift or changing patterns.

This concept is essential for understanding practical deployment and forms a key part of modern AI systems.

Shipping AI Data Drift Changes in input data distribution over time that can degrade model performance in production. Shipping AI Model Monitoring Tracking model performance, data distribution, and predictions in production to detect issues and degradation. Shipping AI Model Retraining Periodically updating models with new data to maintain performance as distributions change. Evaluation Out-of-Distribution Data that differs significantly from the training distribution, where models often perform poorly or unreliably.
