Abstract

A purpose of the present invention is to easily select an appropriate processing format, an appropriate parameter, or the like by predicting a process result that varies according to content of data before executing the process.

According to the present invention, provided is an information processing device including: a feature amount extraction unit configured to extract a feature amount of data serving as a target of a process; a feature amount matching unit configured to match the feature amount with one or more reference feature amounts associated with a prediction result of the process in a database; and a result prediction unit configured to predict a result obtained in a case where the process is executed for the data, on the basis of a result of the matching.

Claims

processing circuitry configured to

receive data from an external device,

extract a feature amount of the data serving as a target of a process,

determine whether the feature amount matches one or more reference feature amounts associated with a prediction result of the process in a database, wherein the matching is executed based on a calculated distance between the extracted feature amount and the one or more reference feature amounts,

in response to a determination that the feature amount matches the one or more reference feature amounts,

predict a result of execution of the process on the data serving as the target of the process based on the matched one or more reference feature amounts, and

execute the process based on the predicted result, and

in response to a determination that the feature amount does not match the one or more reference feature amounts,

execute the process on the data.

2. The information processing device according to claim 1, wherein the processing circuitry is further configured to

decide a setting of the process based on the predicted result.

3. The information processing device according to claim 2, wherein the setting includes a format of the process or a parameter of the process.

4. The information processing device according to claim 1, wherein the processing circuitry is further configured to

add data indicating that the feature amount is treated as a reference feature amount to the database in response to the determination that the feature amount matches.

5. The information processing device according to claim 1, wherein the predicting the result includes predicting the compression rate for compressing the data, quality of the data after the compression, and identity between the data before the compression and the data after the compression.

6. The information processing device according to claim 1, wherein the predicting the result includes predicting cipher strength for encrypting the data.

7. The information processing device according to claim 1, wherein the predicting the result includes predicting process time or an amount of resource consumption for executing the process on the data.

8. The information processing device according to claim 1, wherein the data includes data for displaying an image, and

the processing circuitry is further configured to
