1. A computing device for in silico testing of drugs comprising:
- a processing unit;
a memory;
a genomics module configured to receive genomics information of a patient from an external source and provide the genomics information to a classification module;
a drug selection module configured to identify a plurality of drugs to the classification module for testing to determine if one or more drugs from the plurality of drugs that have more than a threshold probability of affecting at least one physical parameter associated with a condition in the patient; and
the classification module, wherein the classification module is configured to identify one or more drugs from the plurality of drugs that have more than the threshold probability of affecting the at least one physical parameter associated with the condition in the patient based at least in part on the genomics information of the patient.

Abstract
Drug combinations offer promising treatment for some conditions such as cancer. However, the large number of available drug combinations makes it impractical to try all possible combinations. Machine-learning techniques described in this disclosure train a classification algorithm. Once trained, the classification algorithm uses genomic data from a specific patient to perform in silico tests of drugs and drug combinations against the genomic data to determine which therapies are likely to be effective for treating a condition of the specific patient.

8. A method of selecting drugs to administer to a patient, the method comprising:
-
receiving an indication of a condition of the patient; receiving genomics information of the patient; receiving a selection of drugs for in silico testing; providing the condition, the genomics information, and the selection of drugs to a classifier trained with supervised learning to perform the in silico testing; and receiving, from the classifier, identification of one or more drug treatments from the selection of drugs. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of identifying a downstream effect of a drug on a gene that is not a direct target of the drug, the method comprising:
-
identifying a set of gene descriptors that identify a first gene, a second gene, a type of influence between the first gene and the second gene, and a direction of the influence; generating a gene network that includes the first gene, the second gene, and a plurality of other genes, individual genes in the gene network represented by nodes and relationships between the individual genes represented by edges; representing information contained in the gene descriptors as a plurality of n-dimensional real vectors; propagating an effect of the drug on a target gene through the edges of the gene network from the target gene to the gene that is not a direct target of the drug; and determining a probability of the drug influencing the gene that is not the direct target of the drug. - View Dependent Claims (17, 18, 19, 20)
