Iterative Refinement for Personalized Embryo Selection
FedEmbryo introduces a Federated Task-Adaptive Learning (FTAL) approach with a Hierarchical Dynamic Weighting Adaptation (HDWA) mechanism. This innovative framework allows decentralized AI training across multiple IVF clinics while preserving data privacy.
The system integrates multi-task learning (MTL) with federated learning (FL) through a unified architecture combining shared and task-specific layers. HDWA dynamically adjusts weight coefficients based on learning feedback (loss ratios) from individual tasks and clients, ensuring a balanced contribution and robust performance across heterogeneous data environments.
| Task (Metric) | Local Model | FedAvg | FedEmbryo | Improvement over Local |
|---|---|---|---|---|
| Day 1 Pronuclear (AUC) | 0.64 (0.54,0.74) | 0.74 (0.64,0.83) | 0.76 (0.68,0.84) | 18.75% |
| Day 3 Symmetry (AUC) | 0.75 (0.67,0.81) | 0.79 (0.73,0.86) | 0.87 (0.81,0.91) | 16.00% |
| Day 3 Fragmentation rate (PCC) | 0.60 (0.27,0.82) | 0.81 (0.57,0.93) | 0.83 (0.61,0.93) | 38.33% |
| Day 3 Number of cells (PCC) | 0.41 (0.03,0.72) | 0.75 (0.44,0.90) | 0.80 (0.53,0.92) | 95.12% |
| Day 5 Blastocyst formation (AUC) | 0.68 (0.65,0.71) | 0.80 (0.77,0.82) | 0.86 (0.84,0.89) | 26.47% |
FedEmbryo significantly outperforms locally trained models and state-of-the-art FL methods across various embryo morphology assessment tasks. These tasks include pronuclear evaluation, cell symmetry, fragmentation rate, cell count, and blastocyst formation prediction. The HDWA mechanism effectively handles data heterogeneity and improves multi-task learning, demonstrating superior accuracy and robustness on both internal and external test sets.
0.81
Live-Birth Outcome Prediction AUC (Combined Model)
FedEmbryo's multimodal approach, integrating embryo images and clinical factors (maternal age, FSH levels, endometrial thickness), achieves a superior 0.81 AUC for live-birth outcome prediction on external test sets (Cohort E). This represents a 16% enhancement over metadata-only models and 8.57% over local image-based models, highlighting the critical role of combined data for accurate predictions in IVF.
Mitigating Privacy & Data Heterogeneity in IVF Clinics
Challenge: In IVF, patient data is highly sensitive and distributed across clinics (non-IID data), making centralized AI training difficult and prone to bias. Traditional Federated Learning methods often struggle with varied task types and imbalanced datasets across clients.
Solution: FedEmbryo employs a Federated Task-Adaptive Learning (FTAL) framework with a Hierarchical Dynamic Weighting Adaptation (HDWA) mechanism. This allows clients to train local models without sharing raw data, while HDWA dynamically adjusts task and client contributions during aggregation. Shared and task-specific layers accommodate diverse clinical tasks.
Impact: This approach ensures privacy-preserving collaboration and robust model performance across heterogeneous datasets, leading to improved, unbiased predictions for embryo selection and live-birth outcomes, even for clients with smaller datasets.
Enhancing Clinical Trust with Interpretable AI
Challenge: AI models in critical medical decisions, like embryo selection, often act as 'black boxes,' hindering clinician trust and understanding of the underlying reasoning. Transparency is crucial for adoption.
Solution: FedEmbryo integrates Integrated Gradients (IG) for visual explanations on embryo images and SHapley Additive exPlanations (SHAP) for clinical factors. IG generates saliency maps, highlighting influential pixels for morphological assessment (Fig. 4a), while SHAP quantifies the impact of clinical features (e.g., maternal age, FSH) on live-birth predictions (Fig. 4b, c).
Impact: This interpretability module allows embryologists to validate AI decisions, compare them with their own expertise, and gain insights into crucial factors, thereby enhancing confidence and facilitating better-informed clinical decision-making and personalized patient treatments.
