Abstract

fetched live from OpenAlex

Abstract The human tongue has been long believed to be a window to provide important insights into a patient's health in medicine. The present study introduced a novel approach to predict patient age, gender, and weight inferences based on tongue images using pre-trained deep CNNs. Our results demonstrated that the deep CNN models trained on dorsal tongue images produced excellent results for age prediction with a Pearson correlation coefficient of 0.71 and a mean absolute error of 8.5 years. We also obtained an excellent classification of gender, with a mean accuracy of 80% and an AUC of 88%. The model also obtained a moderate level of accuracy for weight prediction, with a Pearson correlation coefficient of 0.39 and a mean absolute error of 9.06 kilograms. These findings support our hypothesis that the human tongue contains crucial information about a patient. This study demonstrated the feasibility of using the pre-trained deep CNNs along with a large tongue image dataset to develop computational models to predict patient medical conditions for non-invasive, convenient, and inexpensive patient health monitoring and diagnosis.

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.
