Every machine learning model is built on data, and that data may contain unintended biases or potential privacy risks. As responsible developers, it’s vital to assess and address these issues to ensure fairness and protect sensitive information. In this article, we will introduce Oracle Guardian AI Open Source Project, a powerful library that provides tools to assess and mitigate bias and estimate privacy risks in machine learning models and datasets.
Assessing Fairness with Oracle Guardian AI
The Fairness module of Oracle Guardian AI offers a wide range of tools to diagnose and understand unintended bias in machine learning models and datasets. One example implementation is the measurement with a fairness metric. To measure fairness, you can use the ModelStatisticalParityScorer class provided by the library. Here’s an example code snippet:
from guardian_ai.fairness.metrics import ModelStatisticalParityScorer
fairness_score = ModelStatisticalParityScorer(protected_attributes='')By using the ModelStatisticalParityScorer class and specifying the protected attribute(s) in your dataset, you can obtain a fairness score that helps assess the presence of bias.
Mitigating Bias with Oracle Guardian AI
The Bias Mitigation module of Oracle Guardian AI focuses on mitigating bias in machine learning models. It provides various techniques to reduce bias and ensure fair outcomes. One implementation example is using the ModelBiasMitigator class. This class takes the original model, protected attribute names, fairness metric, and accuracy metric as parameters. Here’s an example code snippet:
from guardian_ai.fairness.bias_mitigation import ModelBiasMitigator
bias_mitigated_model = ModelBiasMitigator(
model,
protected_attribute_names='',
fairness_metric="statistical_parity",
accuracy_metric="balanced_accuracy",
)
bias_mitigated_model.fit(X_val, y_val)
bias_mitigated_model.predict(X_test)By using the ModelBiasMitigator class with appropriate parameters, you can train a bias-mitigated model that takes fairness and accuracy into account.
Estimating Privacy Risks with Oracle Guardian AI
The Privacy Estimation module of Oracle Guardian AI helps estimate potential information leakage in machine learning models. It focuses on Membership Inference Attacks, which measure the success of attacks on a target model trained on a sensitive dataset to estimate the risk of leakage. Utilizing this module, you can enhance the privacy of your models. Example code implementation for privacy estimation is not provided in the README. However, the library provides functionalities to carry out privacy estimation attacks and measure their success.
In this article, we have explored how Oracle Guardian AI Open Source Project can assist in assessing fairness and privacy in machine learning models and datasets. We have discussed three example code implementations: measuring fairness metrics, mitigating bias, and estimating privacy risks. By utilizing these tools, you can create more inclusive and fair machine learning applications while protecting sensitive information.
