Abstract

We present two surrogate (semi‐empirical) models for prediction of both Protein Adsorption (PA) onto, and Cellular Response (CR) to, the surfaces of biodegradable polymers that have been designed for tissue engineering applications. We explore several of the key issues in the modeling process including the selection of adequate input variables, and the influence of the choice of the training set and the number of input variables on the accuracy of the predictions. The models are each built using five input variables selected from over 800 choices that include experimentally measured values, empirical estimates of chain hydrophobicity, and parameters that describe molecular shape. For both the PA and CR surrogate models, increasing the number of input variables from five up to seventeen resulted in no significant increase in model accuracy. Further, we examined the influence of the number of iterations in a Monte Carlo analysis designed to ensure that the amount of experimental error is realistically accounted for in the models. We found two ANN‐based surrogate models that predict PA and CR for 77 and 71% of the validation sets to within experimental uncertainty, respectively.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
