Topological Inference, Large-Scale Multiple Testing, and Random Positive Definite Matrices
Thu, Jan 12, 2012 @ 02:00 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Armin Schwartzman, Assistant Professor, Department of Biostatistics, Harvard University
Abstract: The first concerns the problem of detecting local significant regions in signals and images, where the need is to make inferences about spatial features such as smooth peaks or compact regions of unknown location rather than individual pixels or voxels. Example include detection of spikes in neuronal recordings, finding protein binding sites in CHIP-Seq genomic data and finding regions of neural activation in brain imaging. Focusing on the 1D case, I propose a topological multiple testing approach involving kernel smoothing and testing of local maxima. Theory and simulation show that global error rates are controlled asymptotically and that the optimal bandwidth corresponds to the âmatched filterâ principle, where the kernel size should be close to that of the peaks to be detected.
Addressing more generally the problem of large-scale testing under arbitrary correlation, such as in gene expression data, I will describe some of the difficulties in making inferences in this setting such as the added bias and variance in the usual false discovery rate (FDR) estimator and the variability of the observed distribution of the test statistics, calling for the so-called empirical null correction.
Finally, relating to geometry and manifold-valued data, I will present statistical tools I have developed for making inferences about eigenvalues and eigenvectors of random symmetric positive definite (PD) matrices. This problem is relevant in the analysis of Diffusion Tensor Imaging data, where the observations themselves ate 3 x 3 PD matrices. The parameter sets involved in the inference problems are subsets of Euclidean space that are either affine subspaces, polyhedral convex cones, or embedded submanifolds that are invariant under orthogonal transformation. A key tool for working with random PD matrices is the matrix log transformation, leading by the central limit theorem to what may be called a matrix-variate log-normal distribution.
Biography: Armin Schwartzman is an Assistant Professor in the Department of Biostatistics at Harvard. He received his Ph.D. in Statistics from Stanford, working with Bradley Efron and Jonathan Taylor. He holds MS and BS degrees in Electrical Engineering and Science Education from Caltech and the Technion (Israel Institute of Technology).

PHOTONICS AND INTEGRATED SYSTEMS SEMINAR
Thu, Jan 12, 2012 @ 03:30 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Willie Ng, HRL Laboratories
Talk Title: Photonics for Microwave Systems and
Abstract: This seminar will describe the development and utilization of photonics technologies in microwave antenna systems and ultra-wideband signal processing. It will cover our recent work on photonic assisted analog-to-digital conversion, the characterization of jitter in mode-locked lasers, frequency-locked photonic oscillators, and the use of Si microdisk heterogeneously integrated with silica waveguides for RF-photonic filtering. In addition, it will also describe how the broadband capabilities of photonics and wavelength division multiplexed (WDM) technologies can be exploited for high dynamic range antenna remoting and true-time-delay beamforming that cover multiple microwave bands.
Biography: Dr. Willie Ng is currently a Principal Research Scientist at HRL Laboratories, Malibu, CA, a research and development company jointly owned by Boeing and General Motors. He has led the photonics effort at HRL since 1997. Under DARPA and Air Force sponsorships, he has led HRL teams that demonstrated a variety of photonic devices/subsystems designed for microwave antenna systems and ultra-wideband signal processing, including RF-photonic filtering and photonics-assisted analog-to-digital conversion. He has given many invited talks in IEEE/OSA Conferences and DARPA Symposiums, and is the author and co-author of over 100 journal articles and conference papers. He holds 20 U.S. patents in the area of photonics technology, with many pending. Cited for pioneering contributions to microwave photonics, he was one of six individuals selected to receive the Excellence in Technology Award in 2005 from the Raytheon Company. Prior to HRL, he was a Member of the Technical Staff in the Rockwell Science Center, Thousand Oaks, Calif. In the Optoelectronics Group of Dr. D. Dapkus, he developed GaInAsP/InP buried heterostructure lasers and power converters. He received his B.S. degree in Electrical Engineering from Case Western Reserve University (Cleveland, Ohio), and his M.S. and Ph.D. degrees in Electrical Engineering from the California Institute of Technology (Pasadena, Calif.) under the guidance of Prof. A. Yariv. His thesis work was on the demonstration of GaAlAs/GaAs Distributed Bragg Reflector lasers and Bragg waveguides. He is a fellow of the IEEE (Class of 2010).
