DeepBridge

DeepBridge is a comprehensive Python library for advanced machine learning model validation, distillation, and performance analysis. It provides powerful tools to manage experiments, validate models, create more efficient model versions, and conduct in-depth performance evaluations.

Installation

You can install DeepBridge using pip:

pip install deepbridge

Or install from source:

git clone https://github.com/DeepBridge-Validation/DeepBridge.git
cd deepbridge
pip install -e .

Quick Start

Model Validation

from deepbridge.core.experiment import Experiment
from deepbridge.db_data import DBDataset

# Create dataset
dataset = DBDataset(
    data=df,
    target_column='target',
    features=['feature1', 'feature2', 'feature3']
)

# Create experiment
experiment = Experiment(
    name='model_validation',
    dataset=dataset,
    models={'my_model': trained_model}
)

# Run validation tests
robustness_results = experiment.run_test('robustness', config='medium')
uncertainty_results = experiment.run_test('uncertainty', config='medium')

# Generate comprehensive report
experiment.generate_report('robustness', output_dir='./reports')

Model Distillation

from deepbridge.distillation import AutoDistiller
from deepbridge.db_data import DBDataset

# Create dataset with predictions
dataset = DBDataset(
    data=df,
    target_column='target',
    features=features,
    prob_cols=['prob_class_0', 'prob_class_1']
)

# Run automated distillation
distiller = AutoDistiller(
    dataset=dataset,
    output_dir='results',
    test_size=0.2,
    n_trials=10
)
results = distiller.run(use_probabilities=True)

Fairness Testing

from deepbridge.core.experiment import Experiment
from deepbridge.db_data import DBDataset

# Create dataset (model already trained)
dataset = DBDataset(
    data=df,
    target_column='approved',
    model=trained_model
)

# Create experiment with protected attributes
experiment = Experiment(
    dataset=dataset,
    experiment_type="binary_classification",
    tests=["fairness"],
    protected_attributes=['gender', 'race', 'age_group']
)

# Run fairness tests
fairness_result = experiment.run_fairness_tests(config='full')

# Check results
print(f"Overall Fairness Score: {fairness_result.overall_fairness_score:.3f}")
print(f"Critical Issues: {len(fairness_result.critical_issues)}")
print(f"EEOC Compliant: {fairness_result.overall_fairness_score >= 0.80}")

# Generate interactive HTML report
fairness_result.save_html('fairness_report.html', model_name='My Model')

Command-Line Interface

# Run model validation
deepbridge validate --dataset data.csv --model model.pkl --tests all

# Generate reports
deepbridge report --results ./results --output ./reports --format interactive

# Train distilled model
deepbridge distill train gbm predictions.csv features.csv -s ./models

# Generate synthetic data
deepbridge synthetic generate --data original.csv --method gaussian_copula --samples 10000
