Objective

The lab set out to build a multimodal AI system capable of interpreting complex industrial scenarios by combining image and text analysis. Success meant hitting 85% accuracy in defect detection while producing natural language explanations that quality control teams could trust.

  • Improve defect detection accuracy with multimodal inputs
  • Provide natural language explanations for inspection findings
  • Train models on domain-specific industrial terminology and defects
  • Deliver production-ready dataset within strict 8-week deadline

The challenge

Limited data, terminology ambiguity, and annotation rework were slowing progress and undermining model reliability:

  • Datasets covered only 22% of industrial equipment types
  • Prior annotation efforts reached just 54% accuracy on component ID
  • Cross-modal alignment showed 43% error in matching defects to descriptions
  • Industry terminology created 38% ambiguity in annotation tasks
  • Timeline required 50k+ samples in 8 weeks (half the standard)
  • Annotation rework rates reached 65% due to domain expertise gaps

CleverX solution

CleverX mobilized a blended team of engineers, inspectors, documentation specialists, and computer vision experts to build a domain-specific dataset with rigorous QA.

Expert recruitment:

  • 8 industrial engineers with 10+ years of floor experience
  • 6 ISO 9001/Six Sigma quality inspectors
  • 4 technical documentation specialists
  • 4 computer vision engineers in industrial automation

Technical framework:

  • Curated 15k image–text pairs spanning 120 equipment categories
  • Built hierarchical labeling schema (defect, severity, remediation)
  • Deployed custom annotation interface (bounding boxes + descriptions)
  • Integrated real-time validation for accuracy on technical components

Quality protocols:

  • Dual expert verification on safety-critical defects
  • Technical accuracy benchmarks validated against OEM specs
  • Weekly calibration with certified industry samples
  • Guidelines covering 200+ industrial scenarios

Impact

The project followed a structured rollout—rapid onboarding, phased annotation, iterative refinement, and quality-validated dataset delivery:

Week 1: Expert onboarding

  • Conducted industrial equipment training
  • Achieved 78% initial annotation accuracy

Weeks 2–4: Large-scale annotation

  • Annotated 18k images with technical descriptions
  • Produced structured defect analyses for pilot dataset

Weeks 5–6: Refinement & feedback loop

  • Incorporated model feedback to reduce error rates
  • Raised cross-modal alignment accuracy to 76%

Weeks 7–8: Final dataset delivery

  • Delivered 52k annotated samples with validation
  • Built 8.5k hard negatives to strengthen model robustness

Result

Efficiency gains:

Optimized workflows cut down cycle time and doubled throughput on dataset creation.

  • Reduced annotation time 8 → 3 minutes per sample
  • Accelerated dataset creation by 50%
  • Cut review cycles in half (4 → 2 iterations)
  • Improved tool efficiency by 35% via expert-driven changes

Quality improvements:

The refined dataset directly improved defect detection and multimodal alignment.

  • Boosted defect detection accuracy 61% → 84%
  • Lifted cross-modal alignment precision by 38%
  • Improved terminology consistency by 45%
  • Reduced false positives on critical defects by 52%

Business impact:

Better models translated to tangible operational and financial benefits for manufacturing clients.

  • Enabled deployment across 5 clients, adding $6.2M revenue
  • Reduced inspection time by 42% in pilots
  • Decreased defect escape rate by 31% in production
  • Prevented quality incidents worth $3.5M annually

Strategic advantages:

The engagement gave the client long-term data assets and processes for ongoing improvements.

  • Created proprietary vision-language dataset
  • Established expert network for continuous iteration
  • Built reusable annotation protocols for industrial AI
  • Secured competitive edge in specialized multimodal models

The lab's multimodal initiative was recognized by a leading manufacturing technology association for innovation in applied AI.
