Extracting interesting knowledge from raw data, or data mining in a broader sense, has become an indispensable task. Nevertheless, data collected from complex phenomena represent often the integrated result of several interrelated variables, whereas these variables are less precisely defined. The basic principle of data mining is to distinguish which variable is related to which and how the variables are related. In many situations, the digitized information is gathered and stored as a data matrix. It is often the case, or so assumed, that the exogenous variables depend on the endogenous variables in a linear relationship. Retrieving \"useful\" information therefore can often be characterized as finding \"suitable\" matrix factorization. This paper offers a synopsis from this prospect on how linear algebra techniques can help to carry out the task of data mining. Examples from factor analysis, cluster analysis, latent semantic indexing and link analysis are used to demonstrate how matrix factorization helps to uncover hidden connection and do things fast. Low rank matrix approximation plays a fundamental role in cleaning the data and compressing the data. Other types of constraints, such as nonnegativity, will also be briefly discussed.","PeriodicalId":443068,"journal":{"name":"International Conference on Informatics Education and Research for Knowledge-Circulating Society (icks 2008)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114726545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of our research is the understanding of an arbitrary sound mixture including music and environmental sounds as well as voiced speech, obtained by robot's ears (microphones) embedded on the robot. Three main issues in computational auditory scene analysis are sound source localization, separation, and recognition of separated sounds for a mixture of speech signals as well as polyphonic music signals. The Missing Feature Theory (MFT) approach integrates sound source separation and automatic speech recognition by generating missing feature masks. This robot audition system has been successfully ported to three kinds of robots, SIG2, Robovie R2 and Honda ASIMO. A robot recognizes three simultaneous speeches such as placing a meal order or a referee for Rock- Paper-Scissors Sound Games with a delay of less than 2 seconds. The real-time beat tracking system is also developed for robot audition. A robot hears music, understands and predicts its musical beats to behave in accordance with the beat times in real-time.","PeriodicalId":443068,"journal":{"name":"International Conference on Informatics Education and Research for Knowledge-Circulating Society (icks 2008)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nagamochi","doi":"10.1109/ICKS.2008.22","DOIUrl":"https://doi.org/10.1109/ICKS.2008.22","url":null,"abstract":"In this paper, we deal with a packing problem that asks to place a given set of objects such as non-convex poly- topes or objects with curved surfaces in a container in R2 or R3 so that the resulting layout of the objects has no penetration of the objects and no protrusion of the objects from the container. Imamichi and Nagamochi proposed a new algorithm scheme, called multi-sphere scheme, which first approximates each object by a set of spheres and finds a layout with no overlap as a local optimal solution of an unconstraint nonlinear program for the sets of shperes. We focus on the case that all objects are rigid, and describe how to design algorithms with the scheme when motions of objects are specified. We handle three variations of motions of objects: \"translation,\" \"translation with a fixed direction,\" and \"translation and rotation by an arbitrary angle.\" We then develop an iterated local search algorithm combining a local search algorithm based on a nonlinear program and perturbation that swaps two objects for the case where \"translation and rotation by an arbitrary angle\" is allowed. Computational experiments disclose our algorithm can find a layout with nearly no penetration and protrusion quickly.","PeriodicalId":443068,"journal":{"name":"International Conference on Informatics Education and Research for Knowledge-Circulating Society (icks 2008)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129119674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
