Abstract
The disclosure is training a recognizer that outputs a recognition result by using a time series of feature data as an input. In addition, the disclosure is setting a data range whose length is a specified time width to a set of feature data to which a time is added, and selecting a specified number of pieces of the feature data from within the data range; adding a teacher label corresponding to the recognition result to the selected plurality of pieces of feature data, whose time order is retained, based on information regarding the plurality of pieces of feature data; and training the recognizer by using, as training data, a set of the plurality of pieces of feature data, whose time order is retained, and the teacher label.
Claims20
A recognizer training device that trains a recognizer that outputs a recognition result by using a time series of feature data as an input, the recognizer training device comprising:
- comprising one or more memories storing instructions and one or more processors configured to execute the instructions to:
- set a data range whose length is a specified time width to a set of feature data to which a time is added, and select a specified number of pieces of the feature data from within the data range;
- add a teacher label corresponding to the recognition result to a selected plurality of pieces of feature data, whose time is retained, based on information regarding the plurality of pieces of feature data;
- and
- train the recognizer by using, as training data, a set of the plurality of pieces of feature data, whose time order is retained, and the added teacher label.
A recognition device comprising one or more memories storing instructions and one or more processors configured to execute the instructions to:
- set a data range whose length is a specified time width to a set of feature data to which a time is added, and select a specified number of pieces of the feature data from within the data range;
- derive a recognition result by inputting, to a recognizer, a selected plurality of pieces of feature data, whose time order is retained;
- and
- output information based on the recognition result.
A data processing method for training a recognizer that outputs a recognition result by using a time series of feature data as an input, the data processing method comprising:
- setting a data range whose length is a specified time width to a set of feature data to which a time is added, and selecting a specified number of pieces of the feature data from within the data range;
- adding a teacher label corresponding to the recognition result to the selected plurality of pieces of feature data, whose time order is retained, based on information regarding the plurality of pieces of feature data;
- and
- training the recognizer by using, as training data, a set of the plurality of pieces of feature data, whose time order is retained, and the teacher label.
18-27. (canceled)
A non-transitory computer-readable storage medium recorded with a program for training a recognizer that outputs a recognition result by using a time series of feature data as an input, the program causing a computer to execute:
- feature data selection processing of setting a data range whose length is a specified time width to a set of feature data to which a time is added, and selecting a specified number of pieces of the feature data from within the data range;
- label addition processing of adding a teacher label corresponding to the recognition result to a plurality of pieces of feature data, which is selected by the feature data selection processing and whose time order is retained, based on information regarding the plurality of pieces of feature data;
- and
- training processing of training the recognizer by using, as training data, a set of the plurality of pieces of feature data, whose time order is retained, and the teacher label added by the label addition processing.
