Hierarchical clustering is a useful data-driven approach to classify complex data and has been used to analyze resting-state functional magnetic resonance imaging (fMRI) data and derive functional networks of the human brain at very large scale, such as the entire visual or sensory-motor cortex. In this study, we developed a voxel-wise, whole-brain hierarchical clustering framework to perform m...

Although relatively neglected in auditory analysis, phase information plays an important role in human auditory intelligibility. This paper investigates a Frequency Modulation (FM) based feature and its contribution to a Language Identification (LID) system, using a Hierarchical LID framework. FM components represent the phase information of a given signal in an AM-FM model. In this paper, we e...

Emerging technologies in BroadbandWireless Access (BWA) networks and video coding have enabled high-quality wireless video broadcast/multicast services in metropolitan areas. Joint source-channel coded wireless transmission, especially using hierarchical/superposition coded modulation at the channel, is recognized as an effective and scalable approach to increase the system scalability while ta...

This paper investigates the combination of evidence coming from different frequency channels obtained filtering the speech signal at different auditory and modulation frequencies. In our previous work [1], we showed that combination of classifiers trained on different ranges of modulation frequencies is more effective if performed in sequential (hierarchical) fashion. In this work we verify tha...

Abstract In unequal error protection (UEP) schemes, the bits are protected according to their significance in terms of distortion reduction capability during reconstruction process. The conventional UEP schemes primarily designed either using forward correction at application layer network architecture, or hierarchical modulation physical layer. this paper, an optimized cross-layer scheme for s...

Binocular rivalry is the alternating percept that can result when the two eyes see different scenes. Recent psychophysical evidence supports an account for one component of binocular rivalry similar to that for other bistable percepts. We test the hypothesis 16, 18 that alternation can be generated by competition between top-down cortical explanations for the inputs, rather than by direct compe...
