Online Dynamic Robust PCA
Mon, Feb 01, 2016 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. Namrata Vaswani, Electrical and Computer Engineering, Iowa State University
Talk Title: Online Dynamic Robust PCA
Abstract: We introduce a novel and provably correct solution approach, called ReProCS, to the online dynamic robust principal components' analysis (PCA) problem. Robust PCA (RPCA) can be understood as a problem of separating a low-rank matrix of the true data, L, and a sparse matrix of outliers, S, from their sum, Y = L + S. Application domains include computer vision and data analytics, among others. For example, the problem of separating sparse foregrounds (e.g., moving objects) from slowly changing backgrounds in video sequences can be posed as an instance of RPCA. This is a key first step in simplifying many computer vision tasks, e.g., video surveillance, low-bandwidth mobile video chats and video conferencing, low-light imaging ("seeing moving objects in the dark") and video denoising. RPCA solutions are also very useful in solving product recommender systems' design problems, such as the Netflix problem, when the user data may contain outliers (e.g., due to lazy or malicious users). While there has been a large amount of recent work on provably correct batch RPCA solutions, the online and dynamic RPCA problem is largely open. Online dynamic RPCA is the problem of solving RPCA on-the-fly, with the extra assumptions that the initial subspace is accurately known and that the subspace from which the true data is generated is either fixed or changes slowly over time. For most of the applications discussed above, an online solution is clearly preferable and it can be argued that these extra assumptions hold. We demonstrate the power of our proposed ReProCS based online dynamic RPCA solution for many of the above applications. Moreover, under mild assumptions, we show that, with high probability, ReProCS recovers the support of the outliers exactly at all times; the subspace in which the true data lies is tracked accurately; and the error in the estimates of both is small at all times.

Speaker: Dr. Achilleas Anastasopoulos, Univ. of Michigan, Ann Arbor
Talk Title: A systematic process for evaluating structured equilibria in dynamic games with asymmetric information
Series: CommNetS
Abstract: We consider problems involving multiple agents making decisions dynamically in the presence of asymmetric information.
When agents have a common objective (dynamic decentralized teams) recent results have established a systematic framework for obtaining the optimal decision strategy that is akin to the well-known backward induction in partially observed Markov decision processes (POMDPs).
However, when agents are strategic (dynamic games with asymmetric information) there is no known systematic process for evaluating the appropriate equilibria in a sufficiently general setting. The well-known backward induction process for finding sub-game perfect equilibria is useless in these problems and we are stuck with an indecomposable fixed-point equation in the space of strategies and beliefs.
In this talk we will discuss a class of perfect Bayesian equilibria (PBE) that are the counterparts of Markov perfect equilibria (MPE) for asymmetric information games. The corresponding "state" is a belief based on the common information among agents.
We will then propose a two-step backward-forward inductive algorithm to find these structured PBE. The backward inductive part of this algorithm defines an equilibrium generating function. Each period in the backward induction involves solving a "small" fixed point equation. Using this generating function, equilibrium strategies and beliefs are defined through a forward recursion.
Biography: Achilleas Anastasopoulos received the Diploma in EE from the National Technical University of Athens, Greece in 1993, and the M.S. and Ph.D. degrees in EE from the University of Southern California in 1994 and 1999, respectively. He is currently an Associate Professor of EECS at the University of Michigan, Ann Arbor. His research interests lie in 1) the general area of communication and information theory, with emphasis in channel coding and multi-user channels; 2) control theory with emphasis in decentralized stochastic control and its connections to communications and information-theoretic problems; 3) analysis of dynamic games and mechanism design for resource allocation in networked systems.

Conferences, Lectures, & Seminars
Speaker: Dion Kai Dickman, PhD, Assistant Professor in Neurobiology, USC Dornsife
Talk Title: Homeostatic control of sleep and synaptic plasticity
Abstract: Homeostatic Control of Sleep and Synaptic Plasticity
Summary
Synapses have the remarkable ability to adaptively modulate synaptic strength in response to perturbations that would otherwise destabilize neurotransmission, referred to as homeostatic synaptic plasticity. Homeostatic signaling systems have emerged as robust and potent regulators of neural activity, enabling stable synaptic function while permitting the flexibility necessary for learning and memory, yet the molecules and mechanisms involved remain poorly understood. We have pioneered forward genetic approaches in Drosophila to identify genes required for homeostatic synaptic plasticity. We will first discuss an enigmatic protein complex that has emerged from this screen, which is associated with schizophrenia, and the role of this complex in synaptic function and homeostatic plasticity. We will then present data about how an individual synapse adapts to conflicting homeostatic perturbations to stable synaptic function. Finally, we are developing new tools, including translational profiling and light sheet microscopy, to reveal homeostatic adaptations to synaptic function, which may be linked to sleep, and ancient, essential, and fundamental homeostatic signaling system shared by all animal life.
Biography: Bio
Dion Dickman was born in Hawaii and did his undergraduate work at Washington University in St. Louis, studying synaptogenesis at the mouse neuromuscular junction in the lab of Joshua Sanes. He went to Harvard for graduate work and UCSF for his postdoctoral studies, performing electrophysiology-based, forward genetic screens in Drosophila, identifying new genes involved in synaptic development, function, and plasticity. He has recently started his own laboratory at the University of Southern California, where his group investigates how synaptic transmission is kept within stable physiological ranges in the nervous system, while still permitting the flexibility necessary for learning and memory. Using Drosophila as our model system, we are interested in the genes and molecular mechanisms that achieve and maintain the homeostatic control of synaptic strength, and how dysfunction in this process may contribute to neuropsychiatric disease. We are using a combination of genetic, electrophysiological, imaging, and behavioral approaches to gain insight into this complex and fundamental form of neural plasticity.

Talk Title: On peculiarities of being a human: Transcriptional regulation in human development and evolution
Series: Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC Distinguished Speakers Series
Abstract: While studies in model organisms have led to great progress in unveiling the conserved mechanisms of gene regulation, many aspects of development that are unique to humans and other primates remain unexplored, as are regulatory principles underlying emergence of human-specific traits. I will discuss some of our recent progress in understanding transcriptional mechanisms governing human development and evolution, such as those involving the activity of transposable elements in early embryogenesis or our recent quantitative analyses of cis-regulatory divergence in the human and chimpanzee neural crest, an embryonic cell population that is most relevant for evolution of human craniofacial form.

How Do Large Networks of Neurons Make Decisions?
Tue, Feb 02, 2016 @ 02:00 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Bijan Pesaran, New York University
Talk Title: How Do Large Networks of Neurons Make Decisions?
Abstract: Abstract: Selecting and planning actions recruits neurons across many areas of the brain but how ensembles of neurons work together to make decisions is unknown. Temporally-coherentneural activity may provide a mechanism by which neurons coordinate their activity in order to make decisions. If so, neurons that are part of coherent ensembles may predict movement choices before other ensembles of neurons. We have been studying activity within the posterior parietal cortex while monkeys make choices about where to look and reach, by decoding the activity to predict the choices. We find that ensembles of neurons that display coherent patterns of spiking activity extending across the parietal cortex, ''dual coherent'' ensembles, predict movement choices substantially earlier than other neuronal ensembles. We propose that dual-coherent spike timing reflects interactions between groups of neurons that play an important role in how we make decisions. I will discuss this result in the context of models of larger scale brain circuits that make decisions. I will finish by presenting our latest efforts to develop new technologies and perform brain-scale investigations of the primate brain.
Biography: Bijan Pesaran is Associate Professor of Neural Science at the Center for Neural Science at New York University. He is also member of NYUs Center for Neuroeconomics. Pesaran is an expert in neuronal dynamics and decision making and has pioneered the study of spike-field coherence in the non-human primate brain. His lab has developed large-scale neurophysiological circuit mapping capabilities to understand how behavior emerges from neuronal activity across interacting brain circuits. He has developed transformative multimodal technology to simultaneously record from single neurons, local potentials and micro-ECoG signals across the cortical layers directly below ECoG recording sites.

Speaker: Professor Lyle Levine, National Institute of Standards and Technology
Talk Title: Additive Manufacturing of Metals: Building Unreliable Microstructures 20 Microns at a Time
Series: Graduate Seminar
Abstract: Additive manufacturing of metals could revolutionize the design and production of complex, high value metal parts. However, the extreme processing conditions of, essentially, welding millions of microscopic bits of metal together, create deleterious microstructures with high stresses, extreme compositional gradients, non-equilibrium phases, and a variety of potentially disastrous build flaws. How can the processing and post processing treatments be optimized to produce useable and consistent microstructures and mechanical properties? We are developing a comprehensive methodology to answer three questions: what is there?, why is it there?, and how can
we fix what is there? To optimize the build and post build processing steps, we are developing and using a combination of multicomponent computational thermodynamic and kinetic microstructural evolution simulations, finite element models, and worldleading stress and microstructure characterization methods using synchrotron X-rays, neutrons, and lab based measurements. I will describe our progress in our first target
systems, Ni-based super alloys and steels.

An Information Theoretic Perspective of Cloud Radio Access Networks

Speaker: Shlomo Shamai, Technion Israel Institute of Technology
Talk Title: An Information Theoretic Perspective of Cloud Radio Access Networks
Abstract: On Cloud Radio Access Networks: Information Theoretic Considerations Cloud radio access networks (C-RANs) emerge as appealing architectures for next-generation wireless/cellular systems whereby the processing/decoding is migrated from the local base-stations/radio units (RU) to a control/central units (CU) in the "cloud". This is facilitated by fronthaul links connecting the RUs to the managing CUs. We focus on oblivious processing at the RU, and hence the fronthaul links carry digital information about the baseband signals, in the uplink from the RUs to the CU and vice versa in the downlink. The high data rate service demands in C-RANs, imply that even with fast (optical) fronthauls, let alone for heterogeneous fronhauls, efficient compression of the basedand signals is essential. In this talk we focus on advanced robust signal processing solutions, emerging by network information theoretic concept and review also the basic approaches to this cloud network. Multi-hop fronthaul topologies are also discussed. Analysis and numerical results illustrate the considerable performance gains to be expected for different cellular models. Some interesting theoretical directions conclude the presentation.

Talk Title: Design at the Nanoscale: Reaching the Limits of Wave-Matter Interactions
Abstract: Nanoscale devices are emerging for an increasing variety of technological applications. Photonics will play a critical role, and within three areas - photovoltaics, nanoparticle scattering, and radiative heat transfer - I will show how large-scale computational optimization and rigorous analytical frameworks enable rapid search through large design spaces, and spur discovery of fundamental limits to interactions between light and matter.
In photovoltaics, the famous ray-optical 4n^2 limit to absorption enhancement has for decades served as a critical design goal, and it motivated the use of quasi-random textures in commercial solar cells. I will show that at subwavelength scales, non-intuitive, computationally designed textures outperform random ones, and can closely approach the 4n^2 limit. Pivoting to metallic structures, where there has not been an analogous "4n^2" limit, I will show how energy-conservation principles lead to fundamental limits to the optical response of metals, answering a long-standing question about the tradeoff between resonant enhancement and material loss. The limits were stimulated by a computational discovery in nanoparticle optimization, where I will present theoretical designs and experimental measurements (by a collaborator) approaching the upper bounds of absorption and scattering. The energy-conservation principles can be extended to the emerging field of radiative heat transfer, where they generalize the ray-optical concept of a "blackbody" to the nanoscale.

Speaker: Linhong Zhu, USC/ISI
Talk Title: Deciphering Dark Web through k-partite Graph Summarization
Series: Natural Language Seminar
Abstract: Facts and their relations extracted from web are commonly modeled as graphs with different types of vertices. In this work, we focus on the problem of revealing latent entities from a $k$-partite graph, by co-clustering $k$ types of different vertices. We propose a CoSum approach, which creates a summary graph, where each super node (a cluster of original vertices) represents a hidden entity and the weighted edges encode important relations among extracted entities. The resulted summary graph also allows for investigation and interpretation of hidden entities. Evaluation verifies that CoSum outperforms several baselines in terms of entity coherence, query supporting and recovering hidden victims in the applied human trafficking domain.
Biography: Linhong Zhu is currently a computer scientist at Information Sciences Institute, University of Southern California, where she also received training as a Postdoctoral Research Associate. Before that, she worked as a Scientist-I in data analytics department at Institute for Infocomm Research, Singapore. She obtained her Ph.D. degree in computer engineering from Nanyang Technological University, Singapore in 2011. Her research interests are large-scale graph analytics with applications to social network analysis, social media analysis, and predictive modeling. She has been awarded with University of Southern California Postdoctoral travel and training award in 2014 and her paper has been selected as two of the best papers in SIGMOD 2010.
