Enterprise AI Analysis: Automatic Identification of Fetal Acidosis Based on Three-Stage Training and Meta-Feature Fusion

AI-Driven Fetal Health

Automated Fetal Acidosis Identification via Three-Stage AI

Traditional fetal cardiotocography (CTG) interpretation suffers from subjectivity and inconsistency, leading to diagnostic unreliability. Existing AI methods often oversimplify acidosis assessment to binary classification, hindering nuanced clinical decisions.

Our innovative Three-Stage Training and Meta-Feature Fusion (TS-MFF) framework systematically addresses these challenges, providing a refined, three-class classification (normal, moderate, severe acidosis) with enhanced accuracy and reliability, even for difficult and imbalanced samples.

Transforming Fetal Health Monitoring with AI Precision

Our proprietary TS-MFF framework redefines fetal acidosis detection, achieving unparalleled accuracy and robust performance across critical diagnostic categories, ensuring timely and informed clinical interventions.

Robustness in Real-World Clinical Data

The framework specifically tackles the two major challenges in real-world fetal heart monitoring: severe class imbalance and the accurate classification of difficult-to-discriminate samples. Our dynamic weighting and targeted enhancement strategies ensure reliable performance where it matters most.

23.62% to 44.70% Improvement in F1 Score for Severe Acidosis (Stage A vs. Stage C)

Mitigating Extreme Class Imbalance in CTG Data

The CTU-CHB dataset, like many real-world clinical datasets, presents a significant challenge: normal samples vastly outnumber acidosis cases, particularly severe ones. This imbalance biases conventional models, leading to poor recognition of critical minority classes. Our dynamic weighting loss in Stage A was specifically designed to adaptively boost the gradient contribution of underrepresented categories, preventing model bias towards the majority class and ensuring initial discriminative ability across all classes.

Furthermore, samples with low confidence or misclassification (difficult samples) represent nuanced physiological states often overlooked by generic models. Stage B targets these specific samples with multimodal feature fusion and enhanced attention mechanisms, extracting finer-grained temporal and clinical patterns. This focused enhancement drastically improves the model's ability to distinguish subtle pathological changes relevant to moderate and severe acidosis, as evidenced by the F1 score for severe acidosis rising from 23.62% with dynamic weighting alone to 44.70% with the full TS-MFF framework.
