SHAP vision SHAP (SHapley Additive exPlanations) is a popular explanation method for deep neural networks that provides insights into the contribution of each input feature to a given prediction. It's based on the concept of Shapley values, which is a method for assigning credit to individual pla...
retinal vascular geometry resulted in a slight improvement in AUC values when added to the metadata model (Supplementary Table6). These results showed that baseline retinal vascular geometry might be predictive patterns for the occurrence of DR, and the fundus model might pick ...
Our results supported this hypothesis as we found higher Shapley values for marker genes compared with randomly chosen features in the Patch-seq GABAergic neuron dataset. Furthermore, we used the Shapley values as a predictor for marker genes. Our results showed that the marker features had ...

SHAP values measure a feature’s influence on a model’s output. High absolute SHAP values signify substantial impact, and positive SHAP values elevate the model’s prediction above the baseline. Fig. 4: Model explainability through the top 10 predictive features for the ChatGPT ADA-selected ...
SHapley Additive exPlanations (SHAP) values26 were calculated and the top 98 features were selected for input into a genetic algorithm. The genetic algorithm produced two sets of features, one short set, containing only 5 features, and another longer set of 37. The short and long feature sets...
