Drift Detection AI Prompt

This prompt detects whether the data or predictions seen in production have drifted away from the training environment. It is useful for model monitoring and retraining decisions after deployment. The analysis prioritizes drift in features that the model actually depends on most.

Prompt text
Detect whether this model's input data or predictions have drifted from the training distribution.

1. Feature drift (data drift): for each feature, compare the training distribution to the current serving distribution using:
   - Kolmogorov-Smirnov test for continuous features
   - Chi-squared test for categorical features
   - Population Stability Index (PSI) for all features
2. Flag features with PSI > 0.2 (significant drift) or PSI 0.1–0.2 (moderate drift)
3. Prediction drift: compare the distribution of model outputs in training vs serving. Has the prediction distribution shifted?
4. Concept drift (if labels are available): compare model performance in recent data vs training data. Has accuracy degraded?
5. Prioritize: which drifting features are most important to the model (high SHAP importance)? These pose the greatest risk.

Return: drift report table per feature, PSI heatmap, and a retraining recommendation: retrain now / monitor / no action needed.

When to use this prompt

Use case 01

A model is in production or being monitored post-training.

Use case 02

You suspect feature distribution or prediction behavior has shifted.

Use case 03

You want statistical drift tests plus PSI-based thresholds.

Use case 04

You need a practical retraining recommendation, not just raw diagnostics.

What the AI should return

A per-feature drift report with tests and PSI values, prediction-drift summary, optional concept-drift check if labels exist, prioritized risk assessment based on feature importance, and a retrain/monitor/no-action recommendation.

Frequently asked questions

What does the Drift Detection prompt do?+

It gives you a structured model evaluation starting point for data scientist work and helps you move faster without starting from a blank page.

Who is this prompt for?+

It is designed for data scientist workflows and marked as advanced, so it works well as a guided starting point for that level of experience.

What type of prompt is this?+

Drift Detection is a single prompt. You can copy it as-is, adapt it, or use it as one step inside a larger workflow.

Can I use this outside MLJAR Studio?+

Yes. The prompt text works in other AI tools too, but MLJAR Studio is the best fit when you want local execution, visible Python code, and reusable notebooks.
