This paper focuss speaker identity verification system from the Department of Electronic Engineering, Tsinghua University (THUEE) for Evalita 2009 Speaker Identity Verification Application Track (SIV-A). Two systems are submitted for the evaluation. The primary one consists of GMM-UBM and GMM-SVM. The contrast one is based on high level feature. We describe each subsystem briefly and give their...

Using biometrics to verify a person’s identity has several advantages such as avoid practice of passwords. Speaker recognition is the process of recognize a people using speaker-specific information contained in a speech signal. Speaker recognition systems can be divided into two modes: identify a particular person or verify a person’s based on claimed identity. Front-end and back-end processin...

Interactive conversation agents or CAs are computer programs or application software designed to simulate conversation with one or more human users in natural language. Providing CAs with knowledge, intelligence and humanoid interface has allowed them to be used in several practical applications. This paper presented the development and its performance of the interactive CAs called Artificial I...

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensiv...

Face processing in the human brain recruits a widespread cortical network based mainly in the ventral and lateral temporal and occipital lobes. However, the extent to which activity within this network is driven by different face properties versus being determined by the manner in which faces are processed (as determined by task requirements) remains unclear. We combined a functional magnetic r...

Several studies demonstrated that face perception is biased by the prior presentation of another face, a phenomenon termed as face-related after-effect (FAE). FAE is linked to a neural signal-reduction at occipito-temporal areas and it can be observed in the amplitude modulation of the early event-related potential (ERP) components. Recently, macaque single-cell recording studies suggested that...

Entity Identity Information Management (EIIM) systems provide the information technology support for Master Data Management (MDM) systems. One of the most important configurations of an EIIM system is identity resolution. In an identity resolution configuration, the EIIM system accepts a batch of entity references and returns the corresponding entity identifiers. However, these batch EIIM syste...

We have developed a data-driven conceptual framework that links two areas of science: the source-filter model of acoustics and cortical sensory processing streams. The source-filter model describes the mechanics behind speech production: the identity of the speaker is carried largely in the vocal cord source and the message is shaped by the ever-changing filters of the vocal tract. Sensory proc...

UNLABELLED The representation of object identity is fundamental to human vision. Using fMRI and multivoxel pattern analysis, here we report the representation of highly abstract object identity information in human parietal cortex. Specifically, in superior intraparietal sulcus (IPS), a region previously shown to track visual short-term memory capacity, we found object identity representations ...
