Abstract

A facility for predicting patient outcomes on the basis of clinical trials is described. The facility obtains information describing one or more completed clinical trials, and extracts features from the obtained clinical trial information. The facility uses the extracted features to train both a time-series data model for predicting clinical outcomes and a non-time-series data model for predicting clinical outcomes. The facility applies these trained models to information describing a subject patient to predict a clinical outcome for the subject patient.

Claims (46)

1. A method in a computing system, comprising:

obtaining information describing one or more completed clinical trials;

extracting features from the obtained clinical trial information;

splitting the extracted features into a first dataset of exclusively time-series data and a second dataset of exclusively non-time-series data;

using the first dataset of exclusively time-series data to train a time-series data model for predicting clinical outcomes;

using the second dataset of exclusively non-time-series data to train an interpretable non-time-series data model for predicting clinical outcomes;

obtaining information describing a subject patient;

splitting the information describing a subject patient into time-series patient data and non-time-series patient data;

applying the time-series data model to the time-series patient data to predict a first clinical outcome for the subject patient;

applying the interpretable non-time-series data model to the non-time-series data to predict a second clinical outcome for the subject patient;

generating a dashboard used to present one or more of: at least a portion of the information describing the subject patient and at least a portion of the obtained clinical trial information;

generating a combined clinical outcome by combining the first clinical outcome with the second clinical outcome; and

presenting the combined clinical outcome within the generated dashboard.

2. The method of claim 1 wherein predicting a clinical outcome for the subject patient comprises merging clinical outcome predictions produced by applying the trained models.

3. The method of claim 1 wherein the time-series data model comprises a recurrent neural network.

4. The method of claim 1 wherein the time-series data model comprises a long short term memory.

5. The method of claim 1 wherein the time-series data model comprises a hierarchical neural attention encoder.

6. The method of claim 1 wherein the interpretable non-time-series data model comprises a forest of gradient-boosted trees.

7. The method of claim 1 , further comprising causing the predicted clinical outcome to be displayed.

8. One or more memories collectively storing a compound patient survival prediction statistical model data structure, the data structure comprising:

a dataset of survival observations obtained from one or more cancer treatment clinical trials, the dataset of survival observations being split into time-series data and non-time-series data;

a first submodel trained to predict patient survival using survival observations obtained from one or more cancer treatment clinical trials, the first submodel being a cyclic neural network, the first submodel exclusively utilizing the time-series data; and

a second submodel trained to predict patient survival using survival observations obtained from one or more cancer treatment clinical trials, the second submodel being a forest of gradient-boosted trees, the second submodel exclusively utilizing the non-time-series data, such that the models represented in the data structure can be applied to information about a patient to predict survival of the patient; and

a dashboard presenting first output generated from applying the time-series data to the first submodel, second output generated from applying the non-time-series data to the second submodel, and one or more of: clinical trial data and patient data.

9. The one or more memories of claim 8 wherein the first submodel is a recurrent neural network.

10. The one or more memories of claim 8 wherein the first submodel is a long short term memory.

11. The one or more memories of claim 8 wherein the first submodel is a hierarchical neural attention encoder.

12. One or more memories collectively having contents configured to cause a computing system to perform a method, the method comprising:

obtaining information describing one or more completed clinical trials;

extracting features from the obtained clinical trial information;

splitting the extracted features into a first dataset of exclusively time-series data and a second dataset of exclusively non-time-series data;

using the first dataset of exclusively time-series data to train a time-series data model for predicting clinical outcomes;

using the second dataset of exclusively non-time-series data to train an interpretable non-time-series data model for predicting clinical outcomes;

obtaining information describing a subject patient;

splitting the information describing a subject patient into time-series patient data and non-time-series patient data;

applying the time-series data model to the time-series patient data to predict a first clinical outcome for the subject patient;

applying the interpretable non-time-series data model to the non-time-series data to predict a second clinical outcome for the subject patient;

generating a dashboard used to present one or more of: at least a portion of the information describing the subject patient and at least a portion of the obtained clinical trial information;

generating a combined clinical outcome by combining the first clinical outcome with the second clinical outcome; and

presenting the combined clinical outcome within the generated dashboard.

13. The one or more memories of claim 12 wherein predicting a clinical outcome for the subject patient comprises merging clinical outcome predictions produced by applying the trained models.

14. The one or more memories of claim 12 wherein the time-series data model comprises a recurrent neural network.

15. The one or more memories of claim 12 wherein the time-series data model comprises a long short term memory.

16. The one or more memories of claim 12 wherein the time-series data model comprises a hierarchical neural attention encoder.

17. The one or more memories of claim 12 wherein the interpretable non-time-series data model comprises a forest of gradient-boosted trees.

18. The one or more memories of claim 12 , the method further comprising causing the predicted clinical outcome to be displayed.
