CRISP-NAM: Competing Risks Interpretable Survival Prediction with Neural Additive Models

CRISP-NAM (Competing Risks Interpretable Survival Prediction with Neural Additive Models), an interpretable neural additive model for competing risks survival analysis which extends the neural additive architecture to model cause-specific hazards while preserving feature-level interpretability.

Overview

This package provides a comprehensive framework for competing risks survival analysis with interpretable neural additive models. CRISP-NAM combines the predictive power of deep learning with interpretability through feature-level shape functions, making it suitable for clinical and biomedical applications where understanding feature contributions is crucial.

Key Features

• Interpretable Architecture: Neural additive models that provide feature-level interpretability through shape functions
• Competing Risks Support: Native handling of multiple competing events in survival analysis
• Comprehensive Evaluation: Nested cross-validation with robust performance metrics (AUC, Brier Score, Time-dependent C-index)
• Hyperparameter Optimization: Automated tuning using Optuna with customizable search spaces
• Rich Visualizations: Automated generation of feature importance plots and shape function visualizations
• Multiple Training Modes: Standard training, hyperparameter tuning, and nested cross-validation
• Baseline Comparisons: DeepHit implementation for benchmarking against state-of-the-art methods
