| 20100217595 | Method For Emotion Recognition Based On Minimum Classification Error - Disclosed herein is a method for emotion recognition based on a minimum classification error. In the method, a speaker's neutral emotion is extracted using a Gaussian mixture model (GMM), other emotions except the neutral emotion are classified using the Gaussian Mixture Model to which a discriminative weight for minimizing the loss function of a classification error for the feature vector for emotion recognition is applied. In the emotion recognition, the emotion recognition is performed by applying a discriminative weight evaluated using the Gaussian Mixture Model based on minimum classification error to feature vectors of the emotion classified with difficult, thereby enhancing the performance of emotion recognition. | 08-26-2010 |

| 20090204362 | INDOOR LOCATION DETERMINATION SYSTEM AND METHOD - Disclosed are a system and a method for an indoor location determination using a matrix pencil. The system comprises a transmitter node that creates and transmits a transmission packet having a plurality of same symbols. A receiver node receives the transmission packet, calculates a delay time by using the symbols in the transmission packet and a matrix pencil algorithm, and calculates a distance between the transmitter node and the receiver node by using the delay time. The delay time estimation using the matrix pencil can reduce an error ratio and therefore can estimate more exactly the distance between the nodes. | 08-13-2009 |
