3Frameworks

Framework

Is model quality degrading (model drift)?

Is input feature distribution shifting?

User session length distribution shifted: median 4.2 min → 1.9 min after app redesign

Training data covers pre-redesign sessions only (data cutoff: 8 months ago)

Are offline metrics (NDCG, MAP) correlated with CTR drop?

NDCG@10 declined from 0.74 to 0.61 in shadow evaluation against live traffic

A/B hold-out shows 2019-era collaborative filter outperforming current model by 14%

Is the feature pipeline producing stale or incorrect signals?

Are real-time behavioral features stale?

User affinity scores update every 6h but browse events lag 4.8h on avg (SLA: 1h)

23% of requests served with affinity scores >12h old during peak load

Is null/missing feature rate rising?

Null rate for "recent-purchase" feature: 3% → 19% after payment-service schema change

Feature monitoring alerts: 0 triggered (alerting threshold set to 25%)

Is serving infrastructure introducing latency or fallback behavior?

Are p99 latency spikes triggering fallback to popularity-based ranking?

Model inference p99: 180ms → 420ms after canary deploy of v3.1 (SLA: 200ms)

38% of requests falling back to non-personalized popularity baseline during peak hours
