Challenges in ASD Diagnosis
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by challenges in social interaction, communication, and restricted or repetitive behaviors. The heterogeneity of ASD symptoms and their overlap with other neurodevelopmental disorders make diagnosis particularly challenging, especially in the early stages of development. Traditional diagnostic methods often fall short in terms of accuracy, scalability, and interpretability. Furthermore, the "black-box" nature of many existing ML models, which lack transparency and interpretability, creates significant hurdles for clinical adoption where clear, actionable insights are critical for informed decision-making.
TabPFNMix & SHAP: The AI Core
This work introduces a novel AI-based framework for ASD diagnosis and parental support, leveraging the TabPFNMix regressor and Shapley Additive Explanations (SHAP). TabPFNMix is a hybrid machine learning model specifically designed for tabular data, combining the strengths of tree-based models with neural networks for superior predictive performance. SHAP, a game-theoretic approach, assigns an importance value to each feature, providing transparent and interpretable reasoning behind the model's predictions, addressing the crucial need for explainability in clinical settings.
Framework Implementation
- Data Preprocessing: Dataset underwent preprocessing including k-NN algorithm for missing values, normalization, and one-hot encoding for categorical variables. Data split into training, validation, and test sets.
- Model Training: TabPFNMix model trained on the training set using cross-validation to optimize hyperparameters and prevent overfitting.
- Model Evaluation: Performance tested on the test set using standard metrics: accuracy, precision, recall, F1-score, and AUC-ROC.
- Explainability Analysis: SHAP values computed for global and local explanations, visualized using summary, dependence, and force plots to interpret model predictions.
- Parental Insights: Key features contributing to ASD diagnosis identified via SHAP, providing actionable insights for early warning and intervention strategies.
- Framework Deployment: User-friendly web application or mobile app, ensuring compliance with data privacy regulations (e.g., HIPAA, GDPR).

Key Influential Factors in ASD Diagnosis (SHAP Analysis)
The SHAP analysis provides crucial insights into the most influential factors driving ASD diagnosis:
- Social responsiveness score: Identified as a high-impact factor, indicating strong contributions to predictive power.
- Repetitive behavior scale: Also highly influential, aligning with established behavioral markers.
- Parental age at birth: Shows moderate to high influence, reinforcing the role of parental factors.
- Parental history of ASD/NDD: Moderate to high influence, suggesting a combined genetic and environmental predisposition.
- Genetic risk score: Identified as a moderate influential factor.
These findings align well with existing medical literature, validating the reliability of the AI-based diagnostic approach and enhancing trust for clinicians and caregivers.
