Dataset QA & Validation
Our QA service validates annotated datasets through automated checks + human review + expert verification. We identify annotation errors, format issues, edge cases, and inconsistencies that could impact model performance.
Annotation accuracy verification and error detection
Ground truth validation and consistency checks
Format compliance testing (COCO, YOLO, Pascal VOC)
Edge case classification and outlier detection
Inter-annotator agreement analysis
Automated + manual QA pipelines
Accuracy Audits
Verify annotation quality from vendors. Independent QA review to measure accuracy, detect systematic errors, and validate that third-party annotated datasets meet your quality requirements.
Data Cleaning
Remove errors and inconsistencies. Identify mislabeled samples, duplicate entries, annotation drift, and outliers that introduce noise into training data.
Ground Truth Validation
Ensure dataset meets training requirements. Expert reviewers validate annotation correctness, class balance, edge case coverage, and overall dataset suitability for your model architecture.
Format Validation
Check compliance with ML frameworks. Automated testing ensures annotation files match expected schemas, coordinate systems are correct, and datasets load properly into training pipelines.
Edge Case Detection
Identify problematic annotations. Statistical analysis flags ambiguous labels, low-confidence samples, and edge cases that require expert review or additional annotation guidelines.
Quality Metrics
Detailed QA reports and statistics. Inter-annotator agreement, class distribution analysis, error rates by category, and actionable insights for dataset improvement.
How QA Saved These Projects
"Lane detection is critical for our autonomous vehicle system. AI Taggers annotated 300k road images with sub-pixel accuracy on curves and intersections. Their attention to detail is unmatched."
Our 3-Layer QA Process
Every dataset goes through automated, peer, and expert validation
Layer 1
Automated Checks Scripts validate format, class distribution, overlaps, and common errors
Layer 2
Peer Review Second annotator reviews random samples for consistency
Layer 3
Expert Validation Domain expert spot-checks edge cases and difficult examples
