Modeling biological effects of molecules using molecular property models
First Claim
1. A method for determining whether one or more test molecules has a biological effect selected from the group consisting of an antibacterial effect, an antiviral effect and an anticancer effect, comprising:
- training on a suitably programmed computer more than three different molecular property models using at least one of a first set of training data, wherein each trained molecular property model is configured to generate a molecular property model prediction regarding a property of interest of the one or more test molecules, wherein said molecular property models are used in determining different properties of interest distinct from the biological effect;
using machine learning techniques to train on a suitably programmed computer system a meta-model to predict the biological effect using a second set of training data, wherein a representation of at least one molecule in the second set of training data includes predictions for the one or more test molecules generated by said molecular property models; and
establishing a prediction, using the computer implemented trained meta-model, that one or more test molecules has the biological effect based on the molecular property model predictions.

Abstract
Method, apparatus, and article of manufacture for modeling the biological effects of a molecule are disclosed. A machine learning application may be configured to process a set of training examples regarding a biological property of interest. Once trained, the machine learning application may be configured to generate a prediction regarding a property of interest for a test molecule. Embodiments of the invention provide a meta-model configured to generate a biological effect prediction for a molecule based on the predictions generated for the test molecule by a plurality of molecular property models.

6. A method for determining whether one or more test molecules has a biological effect selected from the group consisting of an antibacterial effect, an antiviral effect and an anticancer effect, comprising:
-
training on a suitably programmed computer more than three different single target activity models using at least one of a first set of training data, wherein each trained single target activity model is configured to generate a molecular property model prediction regarding a property of interest of the one or more test molecules, wherein said single target activity models are used in determining different properties of interest distinct from the biological effect; using machine learning techniques to train on a suitably programmed computer the meta-model to predict the biological effect using a second set of training data, wherein a representation of at least one molecule in the second set of training data includes predictions for the one or more test molecules generated by said single target activity models; and establishing a prediction, using the computer implemented trained meta-model, that one or more of the test molecules has the biological effect based on the molecular property model predictions. - View Dependent Claims (7, 8, 9, 10, 16)
