It aims at providing compact yet accurate statistical representations for a set of sub-word units. Conventional acoustic modeling is a highly supervised process that requires plenty of speech data with transcriptions. Such resources may not be available for many languages and in many real-world situations. In this lecture, a new framework of unsupervised acoustic modeling is presented. Different types of posterior features are proposed as segment representations. Spectral clustering algorithms are applied to group short speech segments into phone-like units.The resulted acoustic models can be used in many spoken language applications,including spoken term detection, language recognition, and topic identification. 报告题目二：Hyperspectral Unmixing in Remote Sensing: What Do Signal ProcessingPeople Learn from There? 主讲人：Ken Ma副教授主持人：马占宇时间：2014年12月15日（星期一）上午10:00-11:00地点：教三楼811会议室报告摘要：The aim of this talk is tooverview hyperspectral unmixing (HU) techniques from a signal processing researcher’s perspective. HU is one of the most prominent research topics inhyperspectral remote sensing. The problem is to identify materials and the ircorresponding compositions in a captured scene, using the high spectral degrees of freedom of hyperspectral sensors. From a signal processing viewpoint, this is a blind source separation (BSS) problem. We will review how clever insights from remote sensing researchers and recent involvements from other fields, such assignal processing, optimization and machine learning, lead to elegant HU theory and methods – which depart quite significantly from conventional BSS techniques, and in fact, give new insights to BSS theory and methods. The connections of HU toother areas, such as text mining, biomedical imaging and computer vision, may also be discussed, depending on the availability of time. 此讲座为前沿课题讲座，欢迎全校师生踊跃参加。校学术委员会高等智能与网络服务111引智基地国际合作与交流处 2014年12月9日主讲人简介.docx http://portal.bupt.edu.cn//html/main/col51/2014-12/10/20141210111348605555205_1.html
