Continuous Improvement and Feedback Loops - Iterative Governance

Last updated: 2026-04 Status: GA Category: Responsible AI & Governance

Introduksjon

Continuous improvement through feedback loops er et kjernekonsept i moderne AI-governance. Dette handler om systematisk innsamling, analyse og anvendelse av tilbakemeldinger fra produksjonssystemer, brukere og domeneksperter for å forbedre AI-kvalitet, sikkerhet og alignment over tid.

Hvorfor dette er kritisk:

  • AI-modeller degraderer over tid (model drift) grunnet endringer i data og brukeradferd
  • Feedback fra reell bruk identifiserer problemer som ikke fanges i testing
  • Iterative forbedringer basert på produksjonsdata bygger mer pålitelige AI-systemer
  • Compliance og etiske standarder utvikler seg og krever kontinuerlig tilpasning

Microsofts tilnærming: Microsoft implementerer feedback loops gjennom hele AI-livssyklusen – fra utvikling med evaluation datasets til produksjonsmonitoring med automated scorers og human review. Målet er å skape en lukket syklus der hver interaksjon bidrar til systemforbedring.

Kjerneprinsipp:

"Every production interaction becomes an opportunity to improve" – Microsoft MLflow Documentation

Kjernekomponenter

1. Production Data Collection

Tracing og logging:

  • MLflow Traces / MLflow 3 GenAI: Fanger detaljerte execution traces med inputs, outputs og alle mellomsteg for hver interaksjon. (Verified MCP 2026-04)
    • MLflow 3 GenAI introduserer ny Assessment-datamodell med to typer:
      • Feedback assessments: evaluerer faktisk output (ratings, kommentarer — "Var agentens svar bra?")
      • Expectation assessments: definerer ønsket/korrekt output (ground truth — "Hva burde ha blitt produsert"); brukes til å bygge evalueringsdata
    • Tre innsamlingskilder: utvikler (dev), domeneekspert (via Review App), sluttbruker (produksjon)
    • mlflow.log_feedback() API for å knytte bruker-rating og kommentarer til spesifikke traces
    • Ny kapabilitet: Genie Code for naturspråk-analyse av trace-data
    • Integrert tracing for Databricks agentic applikasjoner
  • Azure Monitor & Application Insights: Logger operational metrics, latency, error rates
  • Model Data Collector: Automatisk innsamling av production data for ML-modeller
  • Azure AI Content Safety logs: Sporer content moderation events

Hva samles inn:

  • User prompts og model completions
  • Confidence scores og metadata
  • Latency og performance metrics
  • Error logs og exception traces
  • User feedback (thumbs up/down, ratings)

Confidence: Verified – MLflow Tracing, Azure Monitor

2. Automated Quality Monitoring

LLM-judge based scorers: Microsoft bruker automated scorers (LLM judges) for kontinuerlig kvalitetsvurdering av produksjonstrafikk:

Scorer Type Hva den måler Threshold Eksempel
Groundedness Faktisk forankring i kildedokumenter Pass rate ≥ 70%
Relevance Relevans til brukers spørsmål Pass rate ≥ 70%
Coherence Logisk sammenheng i svar Pass rate ≥ 70%
Fluency Språklig flyt og naturlighet Pass rate ≥ 70%
Safety Deteksjon av harmful content Pass rate ≥ 95%

Continuous evaluation:

  • Schedulert evaluering (f.eks. daglig via CronTrigger)
  • Real-time scoring av sampled production traffic
  • Automated alerts ved threshold violations
  • Integration med Azure AI Foundry evaluation tools

Confidence: Verified – Generation Quality Monitoring

3. Human Feedback Integration

Tre typer feedback:

a) End-user feedback:

  • Explicit feedback: Thumbs up/down, ratings, rapporterte feil
  • Implicit signals: Follow-up spørsmål, avbrutte samtaler, session abandonment
  • Feedback attachet til MLflow traces for traceability

b) Domain expert review:

  • Manuell labeling av problematic traces via Review App
  • Kvalitetsvurdering mot business-specific criteria
  • Alignment av automated scorers med human judgment

c) Human-in-the-loop (HITL):

  • Approval mechanisms for high-impact decisions
  • Reviewer training på AI behavior og vulnerabilities
  • Secure review interfaces med Azure Logic Apps / Power Automate

Confidence: Verified – Human Feedback, HITL Security

4. Evaluation Datasets

Curated eval datasets: Feedback loops bygger evaluation datasets fra produksjonsdata:

  • Problematic traces: Low-scoring eller user-reported issues
  • High-quality traces: Validated positive examples (preservere det gode)
  • Edge cases: Sjeldne scenarios som avdekkes i prod
  • Regression test sets: Sikre at nye versjoner ikke forverrer ytelse

Golden datasets: Benchmark datasets med kjent kvalitet for consistent testing og model validation.

Confidence: Verified – Evaluation Datasets

5. Model Retraining & Versioning

Retraining triggers:

  • Performance degradation under defined KPIs
  • Scheduled retraining (high-risk workloads: månedlig; low-risk: kvartalsvis)
  • Significant data distribution changes
  • New compliance requirements

Versioning best practices:

  • Track code, parameters, evaluation metrics per version
  • MLflow version management for reproducibility
  • Rollback mechanisms for underperforming models
  • A/B testing av nye versjoner mot baseline

Confidence: Verified – Model Management

Arkitekturmønstre

  4. ⚠️ Identify Issues – Trace UI avdekker mønstre i low-scoring traces
  5. 👥 Domain Expert Review – Optional: Eksperter labeler problematic traces
  6. 📋 Build Eval Dataset – Kuratér problematic + high-quality traces
  7. 🎯 Tune Scorers – Align automated scorers med human judgment
  8. 🧪 Evaluate New Versions – Test improved versions mot eval datasets
  9. 📈 Compare Results – Sammenlign evaluation runs på tvers av versjoner
  10. ✅ Deploy or Iterate – Deploy ved forbedring, ellers iterer videre

Verktøy:

  • Azure Databricks MLflow 3
  • Azure AI Foundry Agent Service
  • MLflow Tracing & Scorers

Confidence: Verified – MLflow Continuous Improvement

Mønster 2: AI Builder Feedback Loop (Power Platform)

For custom document processing models:

  1. Power Automate cloud flow kjører AI Builder model på production documents
  2. Condition check: Hvis confidence score < threshold (f.eks. 70%) → add to feedback loop storage
  3. Feedback loop storage: Microsoft Dataverse table "AI Builder Feedback Loop"
  4. Model improvement: Data fra feedback loop brukes til retraining
  5. Retrain & redeploy: Oppdatert model promoteres til production

Use case: Ideal for document understanding scenarios der low-confidence predictions indikerer behov for mer training data.

Confidence: Verified – AI Builder Feedback Loop

Mønster 3: Platform Engineering Feedback Loop

For infrastruktur og platform-tjenester:

  1. Developer feedback: Samle inn pain points (deployment times, tool integration issues)
  2. Post-Incident Reviews (PIRs): Root cause analysis etter incidents
  3. Prioritize improvements: Agile sprints for iterative enhancements
  4. Implement changes: Optimize CI/CD pipelines, integrate developer-friendly tools
  5. Monitor impact: Track developer productivity metrics
  6. Regular platform reviews: Data-driven assessment av platform health

Observability-Driven Development (ODD): Alle nye services instrumenteres for monitoring/logging fra dag 1, slik at feedback er tilgjengelig umiddelbart.

Confidence: Verified – Observability & Continuous Improvement

Beslutningsveiledning

Når bruke hvilke feedback mechanisms?

Scenario Anbefalt Approach Rationale
Conversational AI (chatbots, copilots) MLflow Continuous Improvement Cycle + end-user feedback Høy interaksjonsfrekvens, stor variasjon i queries, behov for human alignment
Non-conversational agents (classification, extraction) Automated scorers + domain expert review for edge cases Mer strukturerte outputs, lettere å automatisere kvalitetsvurdering
Document processing (invoice extraction, form recognition) AI Builder Feedback Loop med confidence thresholds Tydelig confidence metric, retraining med low-confidence examples gir stor effekt
High-risk decisions (healthcare, finance, legal) Mandatory HITL + independent audits + frequent retraining Regulatoriske krav, høy konsekvens ved feil, behov for human oversight
Platform engineering PIRs + developer feedback surveys + observability metrics Fokus på developer experience og system reliability

Retraining frequency guidelines

Microsoft-anbefaling:

Workload Risk Level Retraining Frequency Rationale
High-risk (healthcare, finance, safety-critical) Månedlig eller ved performance degradation Rask tilpasning til data changes, høy konsekvens ved feil
Medium-risk (customer-facing, business-critical) Kvartalsvis Balanse mellom cost og quality maintenance
Low-risk (internal tools, non-critical) Årlig eller ved major data shifts Cost-efficient, akseptabel performance variance

Confidence: Verified – Model Retraining Policies

Quality gates for model promotion

Før en ny modellversjon promoteres til production:

  1. ✅ Evaluation results: Forbedring på target metrics uten regression
  2. ✅ Safety validation: Passed alle safety scorers (violence, hate, self-harm, etc.)
  3. ✅ Regression testing: Eval dataset performance ≥ baseline
  4. ✅ Performance benchmarks: Latency og cost targets møtt
  5. ✅ Compliance check: Alignment med regulatory requirements
  6. ✅ Stakeholder review: Approval fra governance team for high-risk workloads

For arkitekten (Cosmo)

Designprinsipper

1. Close the loop early: Start med enkel feedback collection i MVP, expand iterativt. Ikke vent til "perfekt" monitoring er på plass.

2. Automate, but keep humans in critical paths: LLM judges for scale, domain experts for alignment, HITL for high-stakes decisions.

3. Consistent metrics across environments: Same scorers i development, staging og production – ensures comparability.

4. Treat production data as gold: Real-world interactions are your best test cases. Kuratér dem systematisk.

5. Version everything: Models, prompts, eval datasets, scorers – full reproducibility er non-negotiable.

Anti-patterns å unngå

❌ "Set and forget" monitoring: AI systems degrade over time – continuous attention required ❌ Ignore user feedback: Implicit signals (abandoned sessions) er like viktige som explicit (thumbs down) ❌ Skip regression testing: New versions can break existing functionality – always test against baseline ❌ Overlook cost: Automated scoring kan bli dyrt ved high volume – sample strategically ❌ No clear ownership: Feedback loops fail without dedicated owners (who reviews? who retrains?)

Typiske spørsmål fra kunder

"Hvor ofte bør vi retraine?" → Start med kvartalsvis for low-risk, monthly for high-risk. Adjust basert på performance metrics – hvis model drift er rapid, increase frequency. Always retrain ved major data distribution changes eller compliance updates.

"Hvor stor sample rate for automated scoring?" → 10-20% er et godt utgangspunkt for cost/benefit balance. High-risk workloads kan kreve higher rates (50-100%). Always score 100% av user-reported issues.

"Hvordan prioritere hvilke traces å inkludere i eval datasets?" → Prioritet 1: User-reported issues og low-scoring traces (fix the bad). Prioritet 2: High-quality traces (preserve the good). Prioritet 3: Edge cases og rare scenarios (improve robustness).

"Skal vi bygge custom scorers eller bruke built-in?" → Start med built-in (groundedness, relevance, etc.) – de er well-tested. Add custom scorers for business-specific criteria (f.eks. compliance med internal policies, domain terminology usage). Tune scorers med expert feedback for alignment.

"Hvordan håndtere feedback loops i multi-tenant scenario?" → Separate eval datasets per tenant hvis business requirements differ significantly. Aggregate feedback across tenants for common improvements. Always maintain data isolation per tenant (GDPR/compliance).

"Hva er minimum viable feedback loop?" → 1) Capture production traces, 2) Collect user feedback (thumbs up/down), 3) Manual review av negative feedback, 4) Retrain quarterly. Expand derfra.

Kosmo-spesifikke talking points

Når kunden sier: "Vi har ikke ressurser til kontinuerlig monitoring" Cosmo svarer: "Da starter vi med det minimale: Capture traces + user feedback buttons. Microsoft Copilot Studio har dette built-in. Når volum vokser, add automated scorers for scale. Retraining kan være quarterly – ikke monthly."

Når kunden sier: "Hvordan vet vi om forbedringene virker?" Cosmo svarer: "Det er derfor consistent metrics er kritisk. Du sammenligner evaluation runs før og etter retraining – MLflow evaluation harness gir deg side-by-side comparison. Plus, track production metrics over tid (pass rates, user satisfaction)."

Når kunden sier: "Er ikke LLM judges upålitelige?" Cosmo svarer: "Alone, ja – men tuned med expert feedback, blir de reliable proxies for human judgment. Microsoft anbefaler: Start med built-in judges, sample expert reviews, tune scorers til alignment. Monitor judge performance kontinuerlig."
