Abstract
Autism Spectrum Disorder (ASD) is a prevalent neurodevelopmental condition for which early screening is essential to support timely intervention. Conventional diagnostic procedures are often time-consuming and resource-intensive, highlighting the need for accessible and cost-effective screening approaches. This study investigates the use of deep learning–based facial image analysis as a supportive tool for ASD screening rather than as a diagnostic solution. A comparative evaluation of three state-of-the-art convolutional neural network architectures EfficientNetB0, MobileNetV2, and ResNet50 is conducted using a unified experimental framework based on transfer learning and fine-tuning. Experiments are performed on a publicly available Autistic Children Facial Image Dataset, with an additional verification step to prevent duplicate images in order to enhance generalization and reduce potential bias. All models are trained and evaluated under identical conditions to ensure a fair comparison. Experimental results indicate that EfficientNetB0 achieves the best overall performance, reaching a test accuracy of 88%, while maintaining a favorable balance between model complexity and generalization ability.
The proposed VGG16-based approach has potential as a supportive, non-invasive tool for early ASD screening and is deployed as an interactive, Streamlit-based web application that allows users to upload facial images and receive real-time predictions.
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that manifests itself through unusual social interactions and visual attention. Thus, it is of prime importance to diagnose the condition correctly. In this context, this paper proposes a deep learning-based framework for the detection of Autism Spectrum Disorder by utilizing eye-tracking images. The structured framework of the paper is as follows: the images are first preprocessed through a structured framework involving resizing, min-max normalization, and Otsu threshold-based segmentation. Then, rotation-based data augmentation is performed on the images. Finally, the EfficientNet-B4 network is used in combination with Squeeze-and-Excitation (SE) and Convolutional Block Attention Module (CBAM) for the detection of ASD. The experimental results of the framework have shown that the framework has achieved a classification accuracy of 98.1%, thereby outperforming than other state-of-the-art techniques.

In this paper, we propose Deep Bridge, a unified Convolutional Neural Network (CNN) model that can be considered as a dual task model for healthcare, to solve two important problems: Autism Spectrum Disorder ( ASD ) screening from facial image analysis and recognizing American Sign Language ( ASL ) for better accessibility. It is a hierarchical Multi-Layer Perceptron (MLP) with 512-256-128-64 neurons in each layer, Rectified Linear Unit (ReLU) as an activation function, and Adam optimizer with early stopping regularization. Sixteen 64x64 RGB images were flattened to 12,288-dimensional feature vectors which are required for expression recognition, eye contact pattern and hand gestures essential for classification. Experimental evaluation on synthetic benchmark and clinical data demonstrates strong performance: 94.50% and 96.25% accuracy on autism screening and sign language recognition respectively, with weighted F1-scores of 0.945 and 0.962. In binary classification of autism, the Area Under the Receiver Operating Characteristic Curve (AUC-ROC) is 0.967, which indicates high discriminative power. Statistical robustness is validated through 5-fold cross-validation yielding mean accuracies of 93.82% (+/-1.24%) and 95.68% (+/-0.87%). A web-based Streamlit interface enables real-time screening, with an average of 23.4ms for inference, making it a clinically deployable solution that connects research and clinical application of machine learning.

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects communication skills, social interaction, and behavioral patterns. Early detection is essential for timely intervention; however, conventional diagnostic methods remain time-consuming and subjective, as they rely heavily on clinical observations and expert judgment. This limitation highlights the need for an automated and objective approach to support early ASD screening. This study aims to analyze the performance, stability, and generalization of ASD classification using geometric features extracted from distances between facial landmarks. By representing facial morphology in terms of quantitative spatial relationships, this approach provides a more interpretable alternative to raw image-based methods. This study contributes by proposing a geometric feature representation based on facial landmark distances, providing a comparative analysis between linear and nonlinear classifiers, and ensuring robust evaluation through cross-validation. The dataset consists of 2,032 facial images, evenly distributed between children with ASD and those with typical development. A total of 68 facial landmark points were detected and used to compute pairwise Euclidean distances as classification features. Two classification algorithms, Logistic Regression and Extra Trees Classifier, were evaluated using 5-fold cross-validation to ensure reliable and unbiased performance estimation. The results show that Logistic Regression achieved an average accuracy of 89.91%, precision of 91.04%, recall of 88.56%, and F1-score of 89.76%. Meanwhile, the Extra Trees Classifier outperformed the linear model, achieving an average accuracy of 91.88%, precision of 92.69%, recall of 90.89%, and F1-score of 91.77%. Overall, both models demonstrated stable and consistent performance across validation folds, with the Extra Trees Classifier showing superior ability to capture nonlinear patterns in the data. These findings indicate that geometric feature extraction based on facial landmark distances is effective for ASD detection and has strong potential to be developed as an objective, interpretable, and efficient early screening tool using children’s facial images.
