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 .

Key Features

Experiment Framework

• Modular Architecture: Component-based design with specialized managers

• Feature Selection: Focus testing on specific features with the features_select parameter
• Test Configuration Levels: Quick, medium, or full test suites via the suite parameter
• Visualization System: Integrated visualization capabilities
• Reporting Engine: Detailed HTML report generation

Model Validation

• Multi-faceted Evaluation: Assess models across multiple dimensions
• Alternative Model Comparison: Generate and compare different model types
• Metrics Analysis: Comprehensive performance metrics
• Visualization Tools: Interactive plots for model analysis

Model Distillation

• Knowledge Distillation: Transfer knowledge from complex to simpler models
• Surrogate Modeling: Create lightweight approximations of complex models
• Hyperparameter Optimization: Automated tuning of student models
• Distribution Matching: Ensure student models faithfully reproduce teacher distributions

Advanced Analytics

• Robustness Testing: Evaluate model stability under perturbations
• Uncertainty Quantification: Assess model confidence and calibration
• Resilience Analysis: Test models under adverse conditions
• Hyperparameter Importance: Identify critical hyperparameters

Architecture Overview

DeepBridge has been redesigned with a modular, component-based architecture:

Key Components

• Experiment: Central coordinator managing the experiment workflow
• DataManager: Handles data preparation and splitting
• ModelManager: Creates and manages models and distillation
• TestRunner: Coordinates test execution across managers
• ModelEvaluation: Calculates metrics and evaluates models
• ReportGenerator: Creates HTML reports with results
• VisualizationManager: Coordinates visualization creation

Quick Start

Comprehensive Experiment

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

# Create dataset
dataset = DBDataset(
    data=df,
    target_column='target',
    features=features
)

# Initialize experiment with tests
experiment = Experiment(
    dataset=dataset,
    experiment_type='binary_classification',
    tests=['robustness', 'uncertainty'],
    features_select=['feature1', 'feature2', 'feature3'],  # Optional: Specify features to focus on
    suite='medium'  # Optional: Run tests immediately with this configuration
)

# Train a distilled model
experiment.fit(
    student_model_type='random_forest',
    distillation_method='knowledge_distillation',
    temperature=2.0
)

# If suite parameter wasn't provided, run tests manually
# experiment.run_tests(config_name='medium')
robustness_plot = experiment.plot_robustness_comparison()

# Save comprehensive report
experiment.save_report('experiment_report.html')

Direct Model Distillation

from deepbridge.distillation.techniques.knowledge_distillation import KnowledgeDistillation

# Create distiller directly
distiller = KnowledgeDistillation(
    teacher_model=teacher_model,
    student_model_type='gbm',
    temperature=2.0,
    alpha=0.5
)

# Train the distilled model
distiller.fit(X_train, y_train)

# Make predictions
predictions = distiller.predict(X_test)

Automated Distillation

from deepbridge.auto_distiller import AutoDistiller
from deepbridge.db_data import DBDataset

# Create dataset with probabilities
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)

Command-Line Interface

# Create experiment
deepbridge validation create my_experiment --path ./experiments

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

# Run robustness tests
deepbridge validation test robustness my_experiment --config medium

New Features in This Release

Simplified Experiment Configuration

The Experiment class now supports two new parameters to streamline your workflow:

1. features_select: Focus your analysis on specific features of interest

   # Only test these specific features
   experiment = Experiment(
       dataset=dataset,
       experiment_type='binary_classification',
       tests=['robustness'],
       features_select=['feature_1', 'feature_2', 'feature_3']
   )
   

2. suite: Automatically run tests at initialization with a specific configuration level

   # Tests run automatically with 'quick' configuration
   experiment = Experiment(
       dataset=dataset,
       experiment_type='binary_classification',
       tests=['robustness'],
       suite='quick'
   )
   # Results are immediately available in experiment.full_results
   

3. Combined usage: Use both parameters together for maximum efficiency

   experiment = Experiment(
       dataset=dataset,
       experiment_type='binary_classification',
       tests=['robustness', 'uncertainty'],
       features_select=['feature_1', 'feature_2'],
       suite='medium'
   )
   # Now run the report generation directly
   experiment.full_results.save_report("report.html")
