AIML-03

Is your ML training data vetted, validated, and verified before training the solution's AI model?

Explanation

This question is asking whether your organization has a formal process to ensure the quality, accuracy, and integrity of the data used to train machine learning models before that data is used in training. In machine learning, the quality of the training data directly impacts the performance, reliability, and fairness of the resulting AI model. Poor quality data can lead to biased, inaccurate, or unpredictable model behavior. This question is being asked in a security assessment because: 1. Data integrity concerns: Compromised or manipulated training data could lead to security vulnerabilities in the resulting model 2. Bias and fairness: Unvetted data may contain biases that could lead to discriminatory outcomes 3. Accuracy and reliability: Models trained on invalid or inaccurate data may make incorrect decisions that impact security 4. Data poisoning risks: Without validation, adversaries could potentially inject malicious data to compromise model behavior The guidance specifically mentions looking for: - Formal policies and procedures for data validation - Validation checks on training data - Multiple data labelers to ensure accurate labeling (reducing human error or bias) To best answer this question, you should describe your organization's specific processes for vetting training data, including who is responsible, what validation techniques are used, how data labeling is verified, and how you ensure the data is representative and free from bias or manipulation. Include information about any tools or frameworks used in this process.

Guidance

Looking for policies/procedures about validating and verifying any data used to train the model through validation checks and employing multiple data labelers to validate the accuracy of the data labeling.

Example Responses

Example Response 1

Yes, we have a comprehensive data validation pipeline for all ML training data Our process includes: (1) Automated data quality checks that verify data completeness, consistency, and format correctness; (2) Statistical analysis to identify outliers and anomalous patterns; (3) A multi-stage labeling process where at least three independent annotators review each data point, with conflicts resolved by senior data scientists; (4) Bias detection algorithms that analyze data for potential demographic or representational biases; (5) Provenance tracking to ensure all data sources are documented and authorized; and (6) Regular audits of our training datasets by our AI ethics committee All these procedures are documented in our 'ML Training Data Governance Policy' which is reviewed annually Before any model training begins, the dataset must receive formal sign-off from both our Data Quality team and the AI Ethics Review Board.

Example Response 2

Yes, our ML training data undergoes rigorous validation through our 'Data Trust Framework.' First, all data sources are evaluated for compliance with our data acquisition standards Raw data then passes through our automated data quality pipeline that checks for completeness, consistency, and statistical anomalies For labeled data, we employ a consensus-based approach where each data point is independently labeled by 3-5 domain experts, achieving at least 85% agreement before acceptance We use specialized tools like Snorkel and Cleanlab to programmatically identify potential labeling errors Additionally, our data science team performs regular bias audits using fairness metrics appropriate to each use case All validation results are documented in our Data Quality Management System and reviewed quarterly Any dataset failing our validation criteria undergoes remediation or is rejected from use in training.

Example Response 3

No, we currently don't have a formal validation process for our ML training data Our approach is more ad-hoc, where individual data scientists are responsible for checking their own training data quality We do perform basic cleaning operations like removing duplicates and handling missing values, but we don't have standardized procedures for validating data accuracy or verifying labels We recognize this as a gap in our ML governance framework and are currently developing a more robust data validation pipeline In the interim, we mitigate risks by limiting our ML applications to non-critical business functions and by having peer reviews of datasets before they're used for training We expect to implement a formal data validation process within the next 6 months, including establishing a data quality team and implementing automated validation checks.
