Distinguished Lecturer講演会のご案内

IEEE SPS Sendai Chapterでは,下記のように Distinguished Lecturer 講演会を 開催します.皆様ふるってご参加ください.

  • 日時:2018年6月13日(水)10:30〜12:00
  • 場所:東北大学 電気通信研究所 1階 オープンセミナー室
  • 演題:Generating adversarial examples with a neural network
  • 講演概要:
As neural network classifiers become increasingly successful at various tasks ranging from speech recognition and image classification to various natural language processing tasks and even recognizing malware, a second, somewhat disturbing discovery has also been made.
It is possible to *fool* these systems with carefully crafted inputs that appear to the lay observer to be natural data, but cause the neural network to misclassify in random or even targeted ways.
In this talk we will discuss the problem of designing, identifying, and avoiding attacks by such crafted "adversarial" inputs. We will explain how the basic training algorithms for neural networks may be turned around to learn adversarial examples, and explain why such learning is nearly always possible. Subsequently, we will explain several approaches to producing adversarial examples to fool systems such as image classifiers, speech recognition and speaker verification systems, and malware detection systems. We will describe both "glass box" approaches, where one has access to the internals of the classifier, and "black box" approaches where one does not.

講演題目: Machine Listening: Making Computers that Understand Sound

Enabling machines to perceive the world using various modalities is one of the holy grails of artificial intelligence. In this talk I will present some research on creating machines that do as such by listening. I will discuss some of the unique difficulties in this field and present a thread of research which spans a range of computational disciplines relating to signal processing, machine learning and cryptography. This research will be introduced in the context of classic audio problems such as time/frequency analysis, music transcription, source separation, recognition in mixtures and more. I’ll show how this work generalizes and finds applications to other domains, what its practical implications are, and what it takes to move it from the whiteboard to the real-world.

Title:  Signal Processing for Diagnostic Medicine
Analysis of commonly measured physiological signals can provide many clues about a person’s health.
An example is heart rate variability.  Heart rate variability and other measures of complexity of the heart
rate behavior over time have been used in health assessment of adults, children and fetuses. The first part
of this talk will provide two examples of how heart rate variability and related properties of the circulation system
may be used for early detection of pregnancy-related diseases such as preeclampsia, and to monitor the status of adult sepsis patients. The second part of
the talk will discuss how we can apply signal processing techniques to build tools for reliably and non-invasively monitoring the cardiovascular state of fetuses using
ultrasound techniques. In this part of the talk, we will answer questions such as: (1) How can we accurately
measure heart rate variability in fetuses? (2) How do we noninvasively measure aortic blood pressure in
fetuses?  (3)  Is it possible to measure and track parameters of the fetal circulation system such as the
diameter of fetal arteries and properties such as pulse wave velocity and shear stress on aortic walls?

学術講演会 「情報検索の認知モデル」

講師:神門 典子 教授 (国立情報学研究所)
場所:山形大学 工学部 4-116教室(米沢市城南4−3−16)

共催:IEEE Signal Processing Society Sendai Section

情報検索は, 問い合わせに対して結果を返すというだけのプロセスではない.
対話的,反復的に探索を行っている過程で, 利用者の認知モデルは変化していくと考えられる. このような探索過程における利用者の認知モデルは,情報検索システムとそのインタラクションの設計に必要不可欠であ る.
本講演では,情報検索のプロセスを概説したのち,検索中の認知を計測する研究の動向と, 講演者らの研究とを紹介する.
