Extracting meaning from sound: Experiences in machine hearing

Extracting meaning from sound: Experiences in machine hearing

Richard Lyon, Principal Research Scientist, Google Abstract: Human hearing provides a powerful inspiration for what we might be able to do with machine algorithms, to extract various kinds of meaning and information from sound signals. By modeling the auditory periphery (the cochlea), we can construct a robust representation of what the ear sends to the brain. By modeling the auditory brainstem and midbrain, we make hypothetical representations of the "images" that may project to sheets of auditory cortex as retinal images project to visual cortex. These feature-engineered stages provide a robust foundation for analysis and interpretation of speech, music, sound events, and complicated mixtures and environments. Simple abstractions of these auditory representations have also been shown to be useful improvements over conventional sound-processing front ends. We are also excited to find that visual representations of such front-end features show promise as sound-access aids for users who are deaf or hard-of-hearing. Bio: Richard F. "Dick" Lyon is a Principal Research Scientist at Google, where he leads the Sound Understanding team in applying ideas from human hearing to problems in machine interpretation of sounds of all sorts. He is a Fellow of the IEEE "for contributions to VLSI signal processing, models of hearing, handwriting recognition, and electronic color photography", and a Fellow of the ACM "for contributions to machine perception and for the invention of the optical mouse." In 2005 he received the Progress Medal from the Royal Photographic Society "for the development of the Foveon X3 sensor." He has over 70 issued U.S. patents. In 2017 his book "Machine Hearing: Extracting Meaning from Sound" was published by Cambridge University Press.

Pursuing Fulfillment of the Integrated Machine Drive Vision

Pursuing Fulfillment of the Integrated Machine Drive Vision

Power electronics is an appealing target for physical integration with electric machines, motivated by desires to achieve mass, volume, and cost savings via elimination of special enclosures and connecting cables. Despite some notable successes dating back to the 1960s, there have been a number of formidable obstacles that have limited the successful adoption of this integration technology, including the inability of power electronics to tolerate the thermal and vibration extremes imposed by the machines. Despite these challenges, continuing advances in power electronics (PE) technology are progressively suppressing the barriers to successful integration. Key among these is the accelerating maturity of wide-bandgap (WBG) power semiconductor switches (SiC and GaN) that offer exciting prospects for shrinking the size of power converters by significantly raising their operating frequencies. This presentation explores the future of integrated motor drives (IMDs) by first reviewing key applications and motivating factors that are spurring new research in this field. Looking ahead, the case will be made for a revival of interest in current-source inverters (CSIs) for future machine drives, highlighting the potential of new WBG power switches to update a technology that has been largely dormant for the past 30+ years. If successful, the replacement of today?s standard voltage-source inverters (VSIs) with current-source counterparts offers tantalizing opportunities to simultaneously address EMI, temperature, voltage overshoot, and fault-mode limitations of today?s dominant VSI machine drives. Progress made to date towards achieving these appealing advantages will be highlighted. The presentation will conclude with a review of both the opportunities and challenges presented by emerging technologies such as WBG-based CSI-IMDs for realizing the full potential of the integrated motor drive vision during coming years.

Parity-Time and Other Symmetries in Optics and Photonics

Parity-Time and Other Symmetries in Optics and Photonics

The prospect of judiciously utilizing both optical gain and loss has been recently suggested as a means to control the flow of light. This proposition makes use of some newly developed concepts based on non-Hermiticity and parity-time (PT) symmetry-ideas first conceived within quantum field theories. By harnessing such notions, recent works indicate that novel synthetic structures and devices with counter-intuitive properties can be realized, potentially enabling new possibilities in the field of optics and integrated photonics. Non-Hermitian degeneracies, also known as exceptional points (EPs), have also emerged as a new paradigm for engineering the response of optical systems. In this talk, we provide an overview of recent developments in this newly emerging field. The use of other type symmetries in photonics will be also discussed.

Sensors and cyberphysical sensing networks for water and agriculture

Sensors and cyberphysical sensing networks for water and agriculture

The affordability of computing today, progress in nanomaterials and sensing devices, the increasing availability of data, and the emergence of low power wireless networks have made this an opportune time for the emergence of cyberphysical sensor networks for agriculture, water, and the environment. I will discuss three projects at different stages of development: (i) a two year pilot experiment with Gallo wineries and IBM that used satellite imagery data to calculate and then deliver water to vineyards in a pixelized manner via drip irrigation--resulting in improvements in yield and water efficiency; (ii), the development of Thoreau (Thoreau.uchicago.edu)-the first university based fully sub-terranean sensing network for soil that we have built at the University of Chicago, and (iii) a pilot project or temporal and geospatial mapping of water quality in the Godavari River in Southern India and other large water bodies throughout India. Through the descriptions of these projects I will try to argue that a key bottleneck for ubiquitous use of these technologies lies in the development of cheap, reliable, and scalable sensing packages. I will also describe a few of the key sensing challenges for water and agriculture, and some of our work on developing sensors based upon nanofabricated silicon photonics structures and the functionalization of capture surfaces.

Big (Network) Data: Challenges and Opportunities for Data Science

Big (Network) Data: Challenges and Opportunities for Data Science

How do we draw sound and defensible conclusions from big data? This question lies at the heart of data science. In this talk I will first describe some of the challenges and opportunities inherent in this rapidly emerging field, and then discuss the current state of the art in one area of particular interest: big network data. Progress in this area includes the development of new large-sample theory that helps us to view and interpret networks as statistical data objects, along with the transformation of this theory into new statistical methods to model and draw inferences from network data in the real world. The insights that result from connecting theory to practice also feed back into pure mathematics and theoretical computer science, prompting new questions at the interface of combinatorics, analysis, probability, and algorithms.

Enhancing the resilience of largescale electric grids

Enhancing the resilience of largescale electric grids

Large-scale electric grids are an indispensable critical infrastructure. The impact of the loss of a portion of the electric grid ranges from minor inconveniences to potentially catastrophic when the blackout covers a large region for a long duration. Keeping the lights on involves designing and operating the electric grid with a goal of simultaneously increasing both reliability and resiliency. This talk considers how to enhance resiliency, with a focus on the impact of what the North American Electric Reliability Corporation (NERC) calls High Impact, Low Frequency (HILF) events. Examples include large-scale cyber or physically attacks, pandemics, electromagnetic pulses (EMPs), and geomagnetic disturbances (GMDs). Presented on April 5, 2018, by Professor Thomas J.

Networking coding

Networking coding

"Networking coding: a personal account of combining theory and practice" Network Coding (NC) affords relaxation of constraints and creates opportunities for improved resource usage. Introducing Random Linear Network Coding (RLNC) into TCP requires an inventive reinterpretation of control signals, but recent theoretical results on equivalence theory at MIT show that there is no throughput benefit in combining NC with physical media codes. Come explore the results from the first chip implementation of NC to see how coding is possible at both layers without requiring coordination between them. You?ll also discuss open challenges and research directions driven by the coming convergence of data storage and networking.

Humans, machines, and work: the future is now

Humans, machines, and work: the future is now

Automation, driven by technological progress, has been increasing inexorably for the past several decades. Two schools of economic thinking have for many years been engaged in a debate about the potential effects of automation on jobs: will new technology spawn mass unemployment, as the robots take jobs away from humans? Or will the jobs robots take over create demand for new human jobs? Vardi presents data demonstrating that the concerns about automation are valid. In fact, technology has been hurting working Americans for the past 40 years. The discussion about humans, machines and work tends to be a discussion about some undetermined point in the far future. But it is time to face reality. The future is now.
