Solubility Prediction for Small Molecule using ML and Cheminfo Fingerprints¶
A Floe that predicts solubility of small, drug-like molecules in log uM. It runs a Tensorflow-based fully-connected neural network regression model for prediction. Uses ConvexBox-approach and Tensorflow-based probabilistic fully-connected neural network for domain of application and error bar prediction. Both these Tensorflow models have been trained on 2D Fingerprints.
Finally, it uses LIME, a model agnostic system to explain the solubility of the molecule(s). The Floe is cheap and quick adding about 1.5 seconds for property prediction of 10 molecules.
Outputs:
Failure Dataset : (a) Molecule is too large or too small. or, (b) Molecule has an atom not encountered in the training set.
No Confidence Dataset: Molecule’s deemed out of scope compared to the training set (details below). In this case, the model predictions are unreliable. Explainer image has a red background.
Success Dataset: (a) Falls within scope; explainer has green background. (b) Falls at the edge of scope; explainer has yellow background.
Molecules outside the scope of the training set will be sent to the ‘No Confidence’ port, as a prediction is unreliable. Specifically, the scope is defined as a range in molecular weight, atom count, polar surface area, and calculated logP from the training set molecules. These ranges are reported in the Floe report.
