Feature
Navigating the open seas of graduate school
http://www.ru.uec.ac.jp/e-bulletin/feature/2016/navigating-the-open-seas-of-graduate-school.html
The move from undergraduate studies based on highly structured lecture courses with clearly defined goals and timelines to the nerve racking freedom offered by graduate school is a challenging transition. Here, three UEC graduate students describe their goals and share their aspirations in pursuit of scientific excellence.
Research Highlights
Network traffic anomaly detection - machine learning
"Diagnosing unusual events (called "anomalies") in a large-scale network like Internet Service Providers and enterprise networks is critical and challenging for both network operators and end users," explain Hiroyuki Kasai from The University of Electro-Communications in Japan, and co-authors Wolfgang Kellerer Martin Kleinsteuber at the Technical University of Munich in Germany in a recent report. In their latest work they devise a computationally efficient and effective algorithm to identify network level anomalies by exploiting the state-of-the-art machine learning algorithms, especially the large-scale higher-order tensor tracking technique.
Coding theorem defines decoding error capacity for general scenarios
The rate at which information can be coded so that it can be decoded within a particular error probability constraint is one of the "major research topics in information theory" as Hideki Yagi at the University of Electro-Communications, Te Sun Han at the National Institute of Information and Communications Technology, and Ryo Nomura at Senshu University in Japan explain in their recent report. In this latest work they formulate a theorem for a general class of coding theorems that gives a formula for the decoding error capacity. They also show how the theorem reduces to known theorems for more restricted scenarios.
Engineering: Improvements to a decision-making algorithm
In fields such as engineering, economics or finance, highly complex decisions must be made, often incorporating multiple, at times contradictory, objectives. Highly specialised computer algorithms can help find the best possible solutions to these multi-objective problems (MOPs).
Speech signal processing: Enhancing voice conversion models
Altering a person's voice so that it sounds like another person is a useful technique for use in security and privacy, for example. This computational technique, known as voice conversion (VC), usually requires parallel data from two speakers to achieve a natural-sounding conversion. Parallel data requires recordings of two people saying the same sentences, with the necessary vocabulary, which are then time-matched and used to create a new target voice for the original speaker.
Topics
Evaluating the evaluators: Analysis of big data for peer assessment
Assistant Professor Masaki Uto and Professor Maomi Ueno are pursuing research in areas including machine learning, artificial intelligence, information science, statistics, and educational technology, at the Department of Computer and Network Engineering, Graduate School of Informatics and Engineering, University of Electro-Communications.
Attraction of complex chemistry: Quest for innovative single-molecule magnets
"I am a molecular/crystal designer", says Professor Takayuki Ishida, at the Department of Engineering Science, Graduate School of Informatics and Engineering, University of Electro-Communications. "My research started by trying to answer the question: 'can organic materials be magnetic?' My policy for research in order to answer this question has been: chemical and physical properties must be predictable from structures, and molecular and crystal structures must be designed for target properties."
