GRAIMATTER Green Paper: Recommendations for disclosure control of trained Machine Learning (ML) models from Trusted Research Environments (TREs)

Machine Learning for Educational Data Analysis and Safe Model Deployment

Context: In educational research and analysis, sensitive data is analyzed within secure environments. Researchers and educators utilize machine learning models to derive insights while ensuring compliance with data protection legislation. This includes both training models and deploying them safely in educational settings.

Implementation: Utilization of tools like TensorFlow and scikit-learn within Trusted Research Environments (TREs) and the creation of 'Safe Wrappers' to enforce safe hyperparameters. This approach ensures models are developed and deployed in a manner that prioritizes data privacy and protection compliance.

Outcomes: Enhanced analytical capabilities for educational data while protecting personal information. Improved efficiency in research processes and increased safety in releasing machine learning models, maintaining educational insights.

Challenges: Ensuring models do not unintentionally disclose personal data, managing compliance with evolving legal frameworks, and the need for continuous updates and maintenance of safety protocols.

Predictive Models for Cancer Risk and Treatment Success

Context: In clinical settings, healthcare professionals and researchers utilize predictive models based on patient data to assess cancer risk and predict treatment success. These models aim to facilitate personalized medicine and improve patient outcomes.

Implementation: Training machine learning models on patient data to predict risks of cancer diagnosis and treatment responses. These models are integrated into clinical systems for querying risk predictions and treatment planning, ensuring data security and compliance with medical standards.

Outcomes: Enabled clinicians to assess individual cancer risks and provided probabilities for treatment success, facilitating personalized medicine.

Challenges: Risks associated with disclosing sensitive patient information, particularly regarding high-profile individuals, and maintaining patient confidentiality in clinical applications.

Predictive Models for Employment Outcomes

Context: In recruitment settings, models are employed to predict employment outcomes, specifically focusing on factors such as potential insolvency among candidates with a history of drug use.

Implementation: The model was designed to analyze candidate data to provide insights into employment risks related to drug use. However, the implementation was misused by recruitment agencies for candidate screening.

Outcomes: Intended to help drug users by providing support; however, it resulted in discrimination against candidates based on inferred drug usage.

Challenges: Misapplication of the model led to privacy violations and significant ethical concerns regarding discrimination and bias in recruitment practices.

Technical

Complexity of ML models makes it difficult to assess disclosure risks; traditional disclosure control methods are inadequate. Technical expertise required to implement and maintain machine learning models safely.

Proposed Solutions: Develop tailored disclosure control guidelines specifically for ML models and training programs for researchers and TRE staff to enhance their understanding of machine learning and disclosure controls.

Ethical and Legal

Compliance with data protection legislation is challenging due to the potential for ML models to encode personal data. Legal complexities surrounding the release of machine learning models and the potential for data breaches.

Proposed Solutions: Implement comprehensive ethical and legal frameworks for assessing risks and controls associated with ML models, along with clear legal frameworks and guidelines for data sharing, including contractual obligations for researchers.

Privacy Risk

Potential for sensitive patient information to be disclosed through model predictions.

Proposed Solutions: Implementing differential privacy measures and ensuring that sensitive data is not included in training datasets.

Misuse of AI Models

Models intended for beneficial uses can be misapplied for discriminatory practices.

Proposed Solutions: Establishing strict guidelines and oversight for the use of AI models in sensitive contexts.

Data Security

Vulnerabilities in the model that can lead to attribute and membership inference attacks.

Proposed Solutions: Developing and utilizing more secure modeling techniques, such as differential privacy, to protect training data.
