Abstract

fetched live from OpenAlex

Sensory abnormalities and weak central coherence (WCC), a processing bias for features and local information, are important characteristics associated with autism. This paper introduces a self-organizing map (SOM)-based computational model of sensory abnormalities in autism, and of a feedback system to compensate for them. Feedback relies on a measure of balance of coverage over four (sensory) domains. Different methods to compute this measure are discussed, as is the flexibility to configure the system using different control mechanisms. Statistically significant improvements throughout training are demonstrated for compensation of a simple (i.e., monotonically decreasing) hypersensitivity in one of the domains. Fine-tuning control parameters can lead to further gains, but a standard setup results in good performance. Significant improvements are also shown for complex hypersensitivities (i.e., increasing and decreasing through time) in two domains. Although naturally best suited to compensate hypersensitivities--stimuli filtering may mitigate neuron migration to a hypersensitive domain--the system is also shown to perform effectively when compensating hyposensitivities. With poor coverage balance in the model akin to poor global perception, WCC would be consistent with inadequate feedback, resulting in uncontrolled hyper- and/or hyposensitivities characteristic of autism, as seen in the topologies of the resulting SOMs.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
