(A) For each classification task, data were sampled from all polarization states to train and test the LSTM ML model. Input data were split into training (60%), validation (20%), and testing sets (20%), where validation loss was used to monitor model overfitting.
(B) Macro-averaged class F1 score for the task of classifying each ligand (including unstimulated) across polarization states demonstrates loss of stimulus-response specificity with polarization.
(C) Class F1 scores across polarization states from the same model as in (B).
(D) Confusion fractions across polarization states for different ligand stimulations reveal polarization-dependent patterns in stimulus-response specificity. Error bars in (C) correspond to 95% confidence intervals with n = 15.
