Holistic AI: building trustworthy AI systems

Holistic AI is an open-source library dedicated to assessing and improving the trustworthiness of AI systems. We believe that responsible AI development requires a comprehensive evaluation across multiple dimensions, beyond just accuracy.

Current Capabilities

Holistic AI currently focuses on five verticals of AI trustworthiness:

• Bias: measure and mitigate bias in AI models.
• Explainability: measure into model behavior and decision-making.
• Robustness: measure model performance under various conditions.
• Security: measure the privacy risks associated with AI models.
• Efficacy: measure the effectiveness of AI models.

Quick Start

pip install holisticai  # Basic installation
pip install holisticai[datasets]  # add datasets and plot dependencies
pip install holisticai[bias]  # Bias mitigation support
pip install holisticai[explainability]  # For explainability metrics and plots
pip install holisticai[all]  # Install all packages for bias and explainability

# imports
from holisticai.bias.metrics import classification_bias_metrics
from holisticai.datasets import load_dataset
from holisticai.bias.plots import bias_metrics_report
from sklearn.linear_model import LogisticRegression
from sklearn.preprocessing import StandardScaler

# load an example dataset and split
dataset = load_dataset('law_school', protected_attribute="race")
dataset_split = dataset.train_test_split(test_size=0.3)

# separate the data into train and test sets
train_data = dataset_split['train']
test_data = dataset_split['test']

# rescale the data
scaler = StandardScaler()
X_train_t = scaler.fit_transform(train_data['X'])
X_test_t = scaler.transform(test_data['X'])

# train a logistic regression model
model = LogisticRegression(random_state=42, max_iter=500)
model.fit(X_train_t, train_data['y'])

# make predictions
y_pred = model.predict(X_test_t)

# compute bias metrics
metrics = classification_bias_metrics(
    group_a = test_data['group_a'],
    group_b = test_data['group_b'],
    y_true = test_data['y'],
    y_pred = y_pred
    )

# create a comprehensive report
bias_metrics_report(model_type='binary_classification', table_metrics=metrics)

Key Features

• Comprehensive Metrics: Measure various aspects of AI system trustworthiness, including bias, fairness, and explainability.
• Mitigation Techniques: Implement strategies to address identified issues and improve the fairness and robustness of AI models.
• User-Friendly Interface: Intuitive API for easy integration into existing workflows.
• Visualization Tools: Generate insightful visualizations for better understanding of model behavior and bias patterns.
