Colloquium speaker's recent work

Here is an article recently published in OIST News: "Of Dinosaurs and Mathematics". This is about a work by Robert Sinclair who gave us a very interesting iTHES colloquium last month. Enjoy the article ! http://www.oist.jp/news-center/news/2014/6/5/dinosaurs-and-mathematics

  • Event Report

    "iTHES Weelky Coffee Meeting Continued"
    On 4th July, iTHES Weekly Coffee Meeting was held at the large meeting room on the second floor of the Main Cafeteria. More than 25 iTHES members from all areas have joined, and enjoyed coffee + cake (whichTada san has kindly brought for us) + chat/discussion after some brief self-introduction of each participant. Several people brought their lunch to the meeting room, which is actually a very good idea. In the next meeting (11th July), Tetsuo Hatsuda will give a short presentation on the future of iTHES. See you then !

    Person of the Week

    Ayaka Sakata

    My name is Ayaka Sakata, a SPDR in theoretical biology laboratory. I received Ph.D in 2011 from the University of Tokyo, graduate school of arts and sciences, and after that I worked in Tokyo Institute of Technology for 3 years as a JSPS fellow. I moved to RIKEN this April. I am a member of "Initiative for High-Dimensional Data-Driven Science through Deepening of Sparse Modeling''.

    I am working in the interdisciplinary field of spin-glass theory and statistical machine learning. Analytic tools developed for spin-glasses sometimes give theoretical explanations to heuristics in machine learning based on phase transition pictures. A recipe for the machine learning is how to determine the combination of loss function and regularization, which correspond to Hamiltonian. Statistical mechanics is a potent tool for machine learning, in particular when one would like to evaluate the learning performance approximately.

    My current research theme is learning problems of appropriate overcomplete bases for sparse representation of given data that is seemingly dense. I am also interesting in the evolution of redundant genetic code from the viewpoint of coding problems.
