Abstract - Non-negative spectrogram factorization techniques have become quite popular in the last decade as they are effective in modeling the spectral structure of audio. They have been extensively used for applications such as source separation and denoising. These techniques however fail to account for non-stationarity and temporal dynamics, which are two important properties of audio. In this talk, I will introduce the non-negative hidden Markov model (N-HMM) and the non-negative factorial hidden Markov model (N-FHMM) to model single sound sources and sound mixtures respectively. They jointly model the spectral structure and temporal dynamics of sound sources, while accounting for non-stationarity. I will also discuss the application of these models to various applications such as source separation, denoising, and content based audio processing, showing why they yield improved performance when compared to non-negative spectrogram factorization techniques.

Speaker: Kresimir Matkovic, VRVis Research Center, Vienna Abstract - Increasing complexity and a large number of control parameters make the design and understanding of modern engineering systems impossible without simulation today. Advances in simulation technology and ability to run multiple simulations with different sets of parameters poses new challenges for analysis techniques. In this talk we will present our experiences in exploration and analysis of simulation ensembles realized in several projects with experts from automotive, meteorology, and medical domains. We tightly integrate simulation, numerical optimization, and interactive visual analysis in a unified framework. Our new data model supports families of curves and families of surfaces. Accompanying interactive visual analysis techniques offer new possibilities for data exploration and analysis. It is possible to start with a simple analysis, to continue with identifying hidden features, and finally to explore very complex dependencies using advanced interaction and on-the-fly data derivation and aggregation. All proposed techniques will be illustrated using a coordinated multiple views system and real-life data from various projects with scientists and engineers, including the optimization of an automotive rail injection system.

Abstract - In voice conversion studies, realization of conversion from/to an arbitrary speaker's voice is one of the important objectives. For this purpose, eigenvoice conversion (EVC) based on an eigenvoice Gaussian mixture model (EV-GMM) was proposed. In the EVC, similarly to speaker recognition approaches, a speaker space is constructed based on GMM supervectors which are high-dimensional vectors derived by concatenating the mean vectors of each of the speaker GMMs. In the speaker space, each speaker is represented by a small number of weight parameters of eigen-supervectors. In this talk, we revisit construction of the speaker space by introducing the tensor analysis of training data set. In our approach, each speaker is represented as a matrix of which the row and the column respectively correspond to the Gaussian component and the dimension of the mean vector, and the speaker space is derived by the tensor analysis of the set of the matrices. Our approach can solve an inherent problem of supervector representation, and it improves the performance of voice conversion. Experimental results of one-to-many voice conversion demonstrate the effectiveness of the proposed approach.
