Speaker: Teemu Roos, Helsinki Institute for Information Technology
Talk Title: On Dimension Reduction and Clustering by Random Projections
Abstract: I will discuss some interesting problems and promising solutions related to dimension reduction and clustering by random projections. It is well known that in high dimensional settings, random projections onto lower dimensional subspaces tends to retain pair-wise distances faithfully. Random projections are significantly faster that alternative techniques such as principal component analysis while providing comparable results. In the talk, I will present recent and ongoing work related to speeding up random projection-based computations by parallelization, fast approximate nearest neighbor searches using random projection trees, and applications in dimensional reduction and clustering.
Biography: Teemu Roos is an Assistant Professor at the Helsinki Institute for Information Technology HIIT and the Department of Computer Science, University of Helsinki, Finland. He received his MSc and PhD degrees in computer science from the same university in 2001 and 2007 respectively. Prof Roos's research interests include the theory and applications of probabilistic graphical models, information theory, and machine learning.

Integrated Systems Seminar Series
Fri, Nov 13, 2015 @ 02:00 PM - 03:30 PM

Speaker: Dr. Ichiro Fujimori, IEEE Fellow, Broadcom Corporation
Talk Title: Evolution of Multi-Gigabit Wireline Transceivers in CMOS
Series: Integrated Systems Seminar
Abstract: The Internet Infrastructure is rapidly expanding to meet demands of increasing Internet traffic due to Cloud Computing/Storage. Wireline Transceivers are the data throughput bottleneck for SoCs used in Data Centers, as well as provide the communication backbone for Data Transport Networks. With the Moore's law slowing down, the necessary cost reduction and bandwidth extension with diversified link requirements cannot be achieved by simply taking advantage of a new technology node. As a result, architecture and circuit innovations have become more important than ever for multi-gigabit Wireline Transceivers. Designers will need to explore key questions such as: Analog vs. DSP-based Transceivers, NRZ vs PAM Coding, and Copper vs. Optical Interconnects to come up with the most competitive solution. This talk will provide further insights into these questions, as well as cover the latest advancements in such Wireline Transceivers and Wireline Communications applications.
Biography: Dr. Ichiro Fujimori received the B.S. Degree in Electrical Engineering from the Science University in Tokyo in 1985, and the PhD Degree from the University of Hiroshima in 2003.
In 1985 he joined Asahi-Kasei Microsystems (AKM), Japan, where he was engaged in the design and development of high-resolution Delta-Sigma data converters for Digital-Audio and Communications applications. In 2000, he joined Newport Communications (later acquired by Broadcom). As the Manager of Mixed-Signal Engineering, he led the team to the development of the first CMOS transceiver LSI's for SONET OC-192 applications. He is currently the Vice President of Central Engineering at Broadcom Corporation, responsible for the IP roadmap and development of multi-gigabit SerDes for Networking, transceivers for Optical Communications, Ethernet Copper PHYs, Automotive AFEs, PLLs, and embedded Power Management circuits. He holds 35 U.S. patents.
Dr. Fujimori is an IEEE Fellow, and the recipient of the IEEE Journal of Solid-State Circuits, Best Paper Award in 2000. He has published 35 technical articles, and has conducted various Seminars, Invited talks, and Panels in the field of Data Converters and Wireline Communications. He has served in the Technical Program Committee of VLSI Circuits Symposium from 2009 to 2014, and now in the Executive Committee. He currently serves in the Technical Program Committee of International Solid State Circuits Conference, and as the Associate Editor of the IEEE Journal of Solid-State Circuits.
