Abstract

A data classification apparatus capable of quickly determining an emotion of a driver includes an input device in which a target emotion and an accuracy expectation value of the target emotion are inputted, and a controller rearranging a pre-stored data structure based on the target emotion and the accuracy expectation value of the target emotion, wherein the controller rearranges the data structure so that an accuracy value of the target emotion is secured as much as the accuracy expectation value.

Claims

an input device in which a target emotion and an accuracy expectation value of the target emotion are inputted; and

a controller rearranging a pre-stored data structure based on the target emotion and the accuracy expectation value of the target emotion,

wherein the controller includes at least one processor and at least one of non-transitory memory or transitory memory storing software instructions executed by the at least one processor, and

wherein the controller rearranges the data structure, where an accuracy value of the target emotion is secured as much as the accuracy expectation value.

2. The data classification apparatus according to claim 1,

wherein the controller determines a minimum step of the data structure satisfying the accuracy expectation value of the target emotion and rearranges the data structure based on the determined minimum step.

3. The data classification apparatus according to claim 1,

wherein the input device receives a plurality of target emotions and an accuracy expectation value of each of the target emotions, and

the controller determines a minimum step of the data structure satisfying the accuracy expectation values of the plurality of target emotions and rearranges the data structure based on the determined minimum step.

4. The data classification apparatus according to claim 2,

wherein the controller deletes a feature point of the data structure existing at the minimum step and existing after the minimum step and an emotion value of the data structure existing after the minimum step, and selects a representative emotion value of the deleted feature point of the minimum step.

5. The data classification apparatus according to claim 1,

wherein the controller determines accuracy values of one or more routes proceeding to the target emotion in the data structure and rearranges the data structure based on a minimum step of the route in which an accuracy value among the accuracy values of the one or more routes is equal to or greater than the accuracy expectation value.

6. The data classification apparatus according to claim 1,

wherein the controller determines accuracy values of a plurality of routes proceeding to the target emotion in the data structure, respectively, determines a minimum step necessary for proceeding to a plurality of routes to the target emotion in which the sum of the accuracy values is equal to or greater than the accuracy expectation value, and rearranges the data structure based on the minimum step.

7. The data classification apparatus according to claim 4,

wherein in order to select the representative emotion value, the controller determines one or more emotion values branched from the feature point of the deleted minimum step, calculates the accuracy values of the plurality of routes proceeding to the respective emotion values, respectively, and selects the emotion value proceeding to the route having a largest accuracy value among the calculated accuracy values as a representative emotion value.

8. The data classification apparatus according to claim 1,

further comprising a display device displaying the rearranged data structure.

9. A vehicle comprising:

a biometric device in which biometric information of a driver is inputted; and

a data classification apparatus including an input device in which a target emotion and an accuracy expectation value of the target emotion are inputted, and a controller which rearranges a pre-stored data structure based on the target emotion and the accuracy expectation value of the target emotion,

wherein the controller includes at least one processor and at least one non-transitory memory storing software instructions executed by the at least one processor, and

wherein the controller rearranges the data structure, where an accuracy value of the target emotion is secured as much as the accuracy expectation value, and determines the emotion of the driver corresponding to the biometric information using the rearranged data structure.

10. The vehicle according to claim 9,

wherein the controllerdetermines a minimum step of the data structure satisfying the accuracy expectation value of the target emotion and rearranges the data structure based on the minimum step.
