Abstract Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by core deficits in social communication and the presence of restricted, repetitive behaviors. Its high heterogeneity poses substantial challenges for early identification and diagnosis. Traditional approaches often rely on single-modality data and are constrained by small sample sizes and poor generalization, limiting their utility in clinical decision support. To address these issues, this study proposed a multimodal fusion recognition framework based on hyperdimensional computing (MMHDC). The framework encoded electroencephalography (EEG) and eye-tracking data from 40 children with ASD and 50 typically developing children into hyperdimensional vectors, leveraging the complementary information between neurophysiological and behavioral signals through fusion modeling to enhance recognition accuracy and model robustness. Experimental results showed that the MMHDC model achieved an accuracy of 86.82% using only 5% of the training data, significantly outperforming mainstream methods such as support vector machines, naive Bayes,extreme gradient boosting, and multimodal stacked denoising autoencoders. Further ablation studies demonstrated that combining EEG and eye-tracking features effectively improved discriminative power, highlighting the advantages of a multimodal strategy. By integrating small-sample learning with hyperdimensional encoding theory, this work provided a lightweight and efficient new approach for the early identification of children with ASD, with strong potential for practical deployment and clinical application.
