Abstract

Claims (59)

1 . A computer-implemented method, comprising operations for:

obtaining input features of a first number of features;

identifying hidden features of a second number of new features;

performing quantum feature importance scoring to assign an importance score to each of the input features and to each of the hidden features, wherein the quantum feature importance scoring uses a permutation importance technique;

identifying silent features as the hidden features with the importance score below a first threshold;

identifying important features as the input features with the importance score above a second threshold and the hidden features with the importance score above the second threshold;

building a silent feature model using the silent features;

building an important feature model using the important features;

integrating the silent features and the important features into a single model by building an ensemble model with the silent feature model and the important feature model; and

using the ensemble model to generate one or more predictions and one or more prescriptions comprising one or more recommendations.

2 . The computer-implemented method of claim 1 , wherein the input features include one or more stored features and one or more features identified by web scraping.

3 . The computer-implemented method of claim 1 , wherein the hidden features are identified using a conditional Generative Adversarial Network (cGAN) to generate the second number of the new features.

4 . The computer-implemented method of claim 1 , wherein operations within a Quantum Model Store build the silent feature model and the important feature model.

5 . The computer-implemented method of claim 1 , further comprising operations for:

iteratively creating versions of the silent feature model until a version of the silent feature model is selected for storage based on statistics generated for the silent feature model.

6 . The computer-implemented method of claim 1 , further comprising operations for:

storing one or more versions of the silent feature model and one or more versions of the important feature model in a Quantum Model Store in a computer located in a cloud.

7 . The computer-implemented method of claim 1 , further comprising operations for:

normalizing the silent features; and

scaling the silent features.

8 . A computer program product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform operations for:

obtaining input features of a first number of features;

identifying hidden features of a second number of new features;

performing quantum feature importance scoring to assign an importance score to each of the input features and to each of the hidden features, wherein the quantum feature importance scoring uses a permutation importance technique;

identifying silent features as the hidden features with the importance score below a first threshold;

identifying important features as the input features with the importance score above a second threshold and the hidden features with the importance score above second threshold;

building a silent feature model using the silent features;

building an important feature model using the important features;

integrating the silent features and the important features into a single model by building an ensemble model with the silent feature model and the important feature model; and

using the ensemble model to generate one or more predictions and one or more prescriptions comprising one or more recommendations.

9 . The computer program product of claim 8 , wherein the input features include one or more stored features and one or more features identified by web scraping.

10 . The computer program product of claim 8 , wherein the hidden features are identified using a conditional Generative Adversarial Network (cGAN) to generate the second number of the new features.

storing one or more versions of the silent feature model and one or more versions of the important feature model in a Quantum Model Store in a computer located in a cloud.

14 . The computer program product of claim 8 , wherein the program code is executable by the at least one processor to perform operations for:

normalizing the silent features; and

scaling the silent features.

15 . A computer system, comprising:

one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices; and

program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to perform operations comprising:
