Title:
SELF-TRAINING DATA SELECTION DEVICE, ESTIMATION MODEL LEARNING DEVICE, SELF-TRAINING DATA SELECTION METHOD, ESTIMATION MODEL LEARNING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/202941
Kind Code:
A1
Abstract:
Self-training for an estimation model is performed using a large quantity of utterances with no teacher label. An estimation model learning unit (11) uses a plurality of independent characteristic amounts extracted from utterances with teacher labels to learn an estimation model that estimates a degree of certainty for each prescribed label based on each characteristic amount extracted from input data. A paralanguage information estimation unit (12) uses an estimation model based on characteristic amounts extracted from utterances without teacher labels to estimate a degree of certainty for each label. When the degree of certainty for each label obtained from utterances without teacher labels exceeds all of the preset degree of certainty thresholds for each characteristic amount in relation to the learning object characteristic amount, a data selection unit (13) adds a label corresponding to the degree of certainty to data without teacher labels, as a teacher label, and selects the data as self-training data. An estimation model relearning unit (14) uses the self-training data and relearns the estimation model.
