  • Asiacrypt 2020 to be held in Korea(Daejon)

    During his visit in Asiacrypt 2017 that was held in Hong Kong from December 3rd to 7th, Prof. Kwangjo Kim got the approval to hold the Asiacrypt 2020 in Korea after giving his proposal in the Coordination Committee meeting held in December 4th. Asiacrypt Coordination Committee decides the host country of Asiacrypt that takes place every December. Currently there are up to 3 representatives from each of the 13 countries, including Korea, Japan, China, Taiwan, Hong Kong, Australia, New Zealand, Malaysia, Singapore, Vietnam, UAE and Pakistan. The representatives from Pakistan could not attend this day’s meeting. Korea, Singapore and UAE gave their hosting proposal, and as the result of the voting procdure, Korea got 6 votes and UAE and Singapore got 3 votes each, which didn’t count as majority for Korea. In an additional meeting without the three running countries, the committee chair, Prof. Lai of Shanhai Jiao Tong University, chose Korea as the hosting country. The hosting of Asiacrypt2020 in Korea will be finalized once the IACR Board confirms during Eurocrypt held in Israel next April. Thus Asiacyrpt 2020 is to be held in Korea (Daejeon). The conference is expected to be attended by renowned cryptographers, and that research in cryptography in Korea will mature once more. Prof. Kwangjo Kim is currently IACR Fellow and will serve as the committee chair of Asiacrypt 2020.

  • Prof. Min H. Kim’s research, compact hyperspectral..

    Prof. Min H. Kim’s research project, compact hyperspectral imaging, is in press of EurekAlert Science News and Photonics Media. The traditional hyperspectral imaging technology has wide reach and is being applied in fields such as military combat, astronomy, agriculture, biomedical imaging, and geoscience. Scientists, for instance, rely on hyperspectral imaging to observe and analyze materials for mining and geology, or for various applications in the medical field. However, hyperspectral imaging systems are expensive—ranging from $25,000 to $100,000—and require complex specialized hardware to operate. Prof. Min H. Kim’s team of computer scientists from KAIST, South Korea, and Universidad de Zaragoza, Spain, has devised a way for low-cost accurate hyperspectral imaging, ridding of expensive equipment and complex coding. This novel, compact single-shot hyperspectral imaging method captures images using a conventional DSLR camera equipped with just an ordinary refractive prism placed in front of the lens. The new method was tested on a variety of natural scenes, and the results, according to the researchers, compared well with current state-of-the-art hyperspectral imaging systems, achieving quality images without compromising accuracy. “These hyperspectral imaging systems are generally built for specific purposes such as aerial remote sensing, or military applications, and as such they are not affordable nor practical for ordinary users,” said Min H. Kim, associate professor of computer science at KAIST and a lead author of the study. “Our system requires no advanced skills, and we are able to obtain hyperspectral images at virtually full resolution while making hyperspectral imaging practical.” Prof. Kim’s collaborators include Diego Gutierrez, associate professor at Universidad de Zaragoza; Seung-Hwan Baek, computer science PhD student at KAIST; and Incheol Kim, MS student at KAIST in Min H. Kim’s lab. The team presented their new method at SIGGRAPH Asia 2017 and also published it in the top computer graphics journal, ACM Transactions on Graphics (TOG). This annual conference and exhibition showcases the world’s leading professionals, academics and creative minds at the forefront of computer graphics and interactive techniques.

  • Best Paper in Robotic Planning at the Internationa..

    KAIST School of Computing Ph.D. graduate Junghwan Lee, and M.S. student Heechan Shin (advisor: Prof. Sungeui Yoon) won the Best Paper in Robotic Planning award at the ICAR 2017, held last July 10 through 12 at Hong Kong. The award recognized their research on data-driven kinodynamic RRT. This research was on a method for constructing a database of known possible states and inputs of a kidonynamic robot’s movements for future reference, such that robots can simply search the database. By removing the need to calculate the inputs in real time, the research greatly reduces the computational load of robotic movement. Lee has a history of outstanding academic achievement, having published multiple papers at various internationally renowned journals and conferences during the course of his Ph.D. years, including the IEEE Transaction on Robotics (TRO), International Conference on Robotics and Automation (ICRA), and the International Conference on Intelligent Robotics and Systems (IROS).

  • KAIST SoC Prof. Meeyoung Cha Invited as Keynote Pr..

    KAIST School of Computing Professor Meeyoung Cha presented the keynote for the IEEE/ACM International Conference on ASONAM (Advances in Social Networks Analysis and Mining) with a talk on “The Propagation of Rumors and Fake News”. The conference, held this Aug 1 through 3 at Sydney, Australia, awarded Prof. Cha a plaque of appreciation for her services. The keynote presented an AI based method for detecting fake news online, and the validation of the theory using sociology. This research pointed out the problem that social media, being devoid of any fact checking stage, might propagate false information as if it was true, especially in a society where phones and social media enable a convenient and habitual consumption of information. The research team examined this social phenomenon scientifically, thus proposing a big data and AI algorithm based unsupervised method for online information credibility assessment. The research results were published on various renowned conferences and journals, including ICDM, IJCAI, and PLoS One.

  • SoC Students Win ACM GECCO Humies Silver Award

    A KAIST School of Computing research team led by Professor Shin Yoo won the 2017 Human Competitiveness Award (Humies) Silver Award at Genetic and Evolutionary Computation Conference (GECCO), a conference held by ACM SIGEVO. The event recognizes human parity achievements in research by evolutionary computation. Prof. Yoo’s research contribution involved machine learning based defect location technology (technology for automatically finding defective code found during software testing), which is on parity with existing methods researched by man, and also proved via machine learning that a more accurate method does not exist. Prof. Yoo provided the core elements of the theoretical proof, as well as led an international research team composed of researchers from China’s Wuhan University, Australia’s Swinburne University of Technology, and Briton’s University College London, and then submitted the paper to ACM Transactions on Software Engineering and Methodology in the Humies track. Fourteen teams competed in this year’s Humies track, out of which 9 passed the final selection from a panel of judges. The gold award went to a University of Sidney research team for using genetic algorithms for explaining the causal model of recent quantum entanglement research results. The bronze went to two teams, for a technology to optimize a structure’s truss arrangement, and a technology to optimize A/B testing on websites to maximize customer loyalty. ACM GECCO is a large scale conference with a proud 20 year history in the field of genetic and evolutionary computation research. Its 13 tracks cover various topics, including genetic and evolutionary computation, artificial life, artificial immune systems among others, and welcoms topics on both theory and application. This Humies Award was the 14th such award, created by ex-Stanford Professor John Koza, who greatly contributed to the research of evolutionary computation. Entries must prove via research papers that their evolutionary computation technique shows human parity in their performance in a specific field. Prof. Yoo is a world renown expert in the field of search based software engineering, which uses evolutionary computation techniques to solve software engineering problems.
