The concern in this study is the approach to evaluating the performance of the open-set speaker identification process. In essence, such a process involves first identifying the speaker model in the database that best matches the given test utterance, and then determining if the test utterance has actually been produced by the speaker associated with the best-matched model. Whilst, conventional...

1. Introduction ,(1.1) Let A, B be n x n matrices whose elements are functions holomorphic in a connected open subset V of the complex plane. The matrices A, Bare called pointwise similar on V if for each XE V there exists a non-singular n x n matrix C x with complex elements such that B(x) = C;;l A (x) Cx' They are holomorphically similar on V if there exists a matrix C of functions holomorphi...

The public sector needs to change over to communicating digitally. This development makes great demands both on work processes in the public sector and on the Information Technology systems, on which e-government is based. From the economic perspective, the change-over poses great challenges, as huge investments will have to be made in Information Technology in the public sector. It is therefor...

Large-scale datasets possessing clean label annotations are crucial for training Convolutional Neural Networks (CNNs). However, labeling large-scale data can be very costly and error-prone, and even high-quality datasets are likely to contain noisy (incorrect) labels. Existing works usually employ a closed-set assumption, whereby the samples associated with noisy labels possess a true class con...

This paper is concerned with the verification effectiveness in open-set, text-independent speaker identification. The study includes an analysis of the characteristics of this mode of speaker recognition and the potential causes of errors. The use of well-known score normalisation techniques for the purpose enhancing the reliability of the process is described and their relative effectiveness i...

Automated Genre Identification (AGI) of web pages is a problem of increasing importance since web genre (e.g. blog, news, eshops, etc.) information can enhance modern Information Retrieval (IR) systems. The state-of-the-art in this field considers AGI as a closed-set classification problem where a variety of web page representation and machine learning models have intensively studied. In this p...

The development style of open source has a possibility to create new business markets for Regional IT industries. Some local governments are trying to promote their regional IT industries by adopting an open source in their electronic government systems. In this paper, we analyze the data of open source application policy of the Japanese government and case studies of promotion policy of local ...
