Abstract

Disclosed are the methods and systems for classifying one or more patients in one or more categories. A distribution of one or more physiological parameters associated with the one or more patients is determined based on a patient dataset. The one or more physiological parameters correspond to at least a stroke scale score. One or more parameters associated with a copula are estimated by the one or more processors. In an embodiment, the copula defines a joint distribution of the one or more physiological parameters. A classifier is created based on the one or more parameters, wherein the classifier classifies the one or more patients in the one or more categories. The one or more categories correspond to a range of the stroke scale score.

Claims

1. A method for classifying one or more patients in one or more categories, the method comprising:

determining, by one or more processors, a distribution of one or more physiological parameters associated with the one or more patients based on a patient dataset, wherein the one or more physiological parameters comprise at least a stroke score;

estimating, by the one or more processors, one or more parameters associated with a copula defining a joint distribution of the one or more physiological parameters; and

creating, by the one or more processors, a classifier based on the one or more parameters, wherein the classifier classifies the one or more patients in the one or more categories, wherein the one or more categories correspond to a range of the stroke score.

2. The method of claim 1, wherein the one or more physiological parameters comprise at least one of an age, a number of days between an onset of a stroke and a first medical consultation, a hemoglobin count, a RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count.

3. The method of claim 1, wherein the classifier is a Bayesian classifier.

4. The method of claim 1 further comprising categorizing, by the one or more processors, a human subject, different from the one or more patients, in the one or more categories based on one or more physiological parameters associated with the human subject, wherein the stroke score of the human subject is unknown.

5. The method of claim 4 further comprising determining, by the one or more processors, at least one of a treatment course for the human subject, an emergency care decision associated with the human subject, or a rehabilitation course for the human subject, based on the categorization of the human subject in the one or more categories.

6. The method of claim 1 further comprising transforming, by the one or more processors, the patient dataset into a ranked dataset, wherein the ranked dataset corresponds to the patient dataset sorted based on a physiological parameter from the one or more physiological parameters.

7. A method for categorizing one or more patients in one or more categories, the method comprising:

creating, by one or more processors, a classifier based on a patient dataset comprising a measure of one or more physiological parameters of the one or more patients, wherein the one or more physiological parameters comprise at least a measure of a stroke score; and

classifying, by the one or more processors, the one or more patients in the one or more categories based on the classifier, wherein the one or more categories correspond to a range of the stroke score.

8. The method of claim 7, wherein the one or more physiological parameters comprise at least one of an age, a number of days between an onset of a stroke and a first medical consultation, a hemoglobin count, a RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count.

9. The method of claim 7 further comprising training, by the one or more processors, the classifier based on one or more machine learning techniques comprising at least one of a Support Vector Machine (SVM), a Logistic Regression, a Naï

ve Bayes Classifier, a Decision Tree Classifier, or a Copula-based Classifier.

10. The method of claim 7, wherein the classifier is a Bayesian classifier.

11. The method of claim 7 further comprising categorizing, by the one or more processors, a human subject, different from the one or more patients, in the one or more categories based on one or more physiological parameters associated with the human subject, wherein the stroke score of the human subject is unknown.

12. The method of claim 11 further comprising determining, by the one or more processors, at least one of a treatment course for the human subject, an emergency care decision associated with the human subject, or a rehabilitation course for the human subject, based on the categorization of the human subject in the one or more categories.

13. A system for classifying one or more patients in one or more categories, the system comprising:

one or more processors configured to;

determine a distribution of one or more physiological parameters associated with the one or more patients based on a patient dataset, wherein the one or more physiological parameters comprise at least a stroke score;

estimate one or more parameters associated with a copula defining a joint distribution of the one or more physiological parameters; and

create a classifier based on the one or more parameters, wherein the classifier classifies the one or more patients in the one or more categories, wherein the one or more categories correspond to a range of the stroke score.

14. The system of claim 13, wherein the one or more physiological parameters comprise at least one of an age, a number of days between an onset of a stroke and a first medical consultation, a hemoglobin count, a RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count.

15. The system of claim 13, wherein the classifier is a Bayesian classifier.

16. The system of claim 13, wherein the one or more processors are further configured to categorize a human subject, different from the one or more patients, in the one or more categories based on one or more physiological parameters associated with the human subject, wherein the stroke score of the human subject is unknown.

17. The system of claim 16, wherein the one or more processors are further configured to determine at least one of a treatment course for the human subject, an emergency care decision associated with the human subject, or a rehabilitation course for the human subject, based on the categorization of the human subject in the one or more categories.

18. A computer program product for use with a computing device, the computer program product comprising a non-transitory computer readable medium, the non-transitory computer readable medium stores a computer program code for classifying one or more patients in one or more categories, the computer program code is executable by one or more processors in the computing device to:

determine a distribution of one or more physiological parameters associated with the one or more patients based on a patient dataset, wherein the one or more physiological parameters comprise at least a stroke score;

estimate one or more parameters associated with a copula defining a joint distribution of the one or more physiological parameters; and

create a classifier based on the one or more parameters, wherein the classifier classifies the one or more patients in the one or more categories, wherein the one or more categories correspond to a range of the stroke score.

19. The computer program product of claim 18, wherein the one or more physiological parameters comprise at least one of an age, a number of days between an onset of a stroke and a first medical consultation, a hemoglobin count, a RBC count, a creatinine count, a serum sodium count, a blood albumin count, a blood platelet count, or a complete blood count.

20. The computer program product of claim 18, wherein the classifier is a Bayesian classifier.
