Speech Title: Autonomous Vehicle Guidance using Independently Moving Cameras

Abstract: Autonomous Vehicles (or self-driving cars) are one of the hottest toptics in the world of tech right now, with many companies like Waymo and Tesla having already released, or soon to release, self-driving features. Each vehicle is usually outfitted with a GPS unit, an inertial navigation system, and a range of sensors including laser rangefinders, radar, and video. The vehicle typically uses positional information from the GPS and inertial navigation system to localize itself and sensor data to refine its position estimate as well as to detect obstacles. In this talk, I will discuss how we can use independently moving cameras to provide input to an autonomous vehicle that will allow it to navigate through an environment to target locations without using global localization systems like GPS. In addition, I will talk about how we can use moving cameras to recover the distance of an object that is simultaneously moving with (but independently from) the autonomous vehicle.



He received M. Eng. and D. Eng. Degrees in mechanical engineering from Tohoku University in 1983 and 1985, respectively. He was a research associate at Tohoku University in 1985 and a lecturer at Miyagi National College of Technology, and a visiting professor at the University of California, Los Angeles. Since 1991, he has been with the Faculty of Engineering, Gifu University and is currently a professor.

Speech Title: Vibration control of a flexible manipulator

Abstract: Despite the numerous advantages associated with the flexible link manipulators; low power consumption, use of small actuators, high speed and their low cost due to fewer materials requirements than their rigid counterparts, link vibrations stand in the way to reaping these benefits. This leads to time wastage waiting for vibrations to decay to safe operating levels and the possibility of mechanical failure due to vibration fatigue. This drawback has been addressed using techniques such as adaptive filters, adaptive strain feedback gain, piezoelectric transducers, etc. What was gained in operation speed was lost in waiting for the vibrations to decay to healthy levels for operation. The plant presented in this article is a 3D, two-link flexible manipulator with a variable weight attached at the distal end. It has three rotary joints driven by dc servomotors and the two flexible links assumed to have damping of the kelvin-voigt type both in the lateral and the torsional senses. The control system consists of a computer, AD and DA converters interfaced to Matlab and controlled from dSPACE control desk environment. Measurement of angular position and velocity is achieved using encoders coupled to the servomotors while link strain measurement is done by strain gauges positioned at the bottom of each link. This ongoing work seeks to contribute by developing high-speed control methods for a 3D two-link flexible manipulator. To this end, we have modelled the manipulator and validated the similarities of the model with the actual manipulator in terms of joint angles, joint velocities, link strains and power spectrum in frequency domain. The first control method involved the development of an inverse controller which was augmented with lowpass filters. Experimental results show that with careful choice of the filter order and time constant, this technique significantly reduces transient vibrations in comparison to a system without a controller. Further extension of this technique yielded a two-degree-of-freedom controller design between a filtered inverse controller and strain feedback which addressed residue vibrations resulting in a superior controller. Collocated controller, though very effective in reducing the rise time are poor in increasing the damping of the system. Non-collocated control, in the control of flexible manipulators is limited by the difficulties in the estimation of the position of the end-effector from the joint angle. Research has shown that non-collocated control where a proportion of root strain is implemented as a negative feedback increases system damping. However, too high gain results in encoder noise feedback while too little is not good for vibration suppression. Determination of the right proportion of root strain to feed back, and the timing is a research problem that has not been solved yet. Further experiments were conducted seeking to tune strain feedback gains using the artificial neural network by training using online backpropagation algorithm. Results showed that neural network could intelligently choose appropriate gains depending on the intensity of the link strain, yielding a system characterized by minimal vibrations relative to a system with constant controller gain. Since loading the manipulator is accompanied by an increase in strain intensity and a reduction in the vibration frequency, the technique could sense changes in loading and adjust the gains accordingly.

Speech Title: AI Doctor and Smart Medical Imaging with Deep Learning

Abstract: It is said that artificial intelligence driven by deep learning would make the 4th Industrial Revolution. Deep leaning becomes one of the most active areas of research in computer vision, pattern recognition, and imaging fields, because “learning from examples or data” is crucial to handling a large amount of data (“big data”) coming from informatics and imaging systems. Deep learning is a versatile, powerful framework that can acquire image-processing and analysis functions through training with image examples; and it is an end-to-end machine-learning model that enables a direct mapping from raw input data to desired outputs, eliminating the need for handcrafted features in conventional feature-based machine learning. I invented ones of the earliest deep-learning models for image processing, semantic segmentation, object enhancement, and classification of patterns in medical imaging. I have been actively studying on deep learning in medical imaging in the past 23 years. In this talk, AI-aided diagnosis and smart medical imaging with deep learning are introduced, including 1) computer-aided diagnosis for lung cancer in CT, 2) distinction between benign and malignant lung nodules in CT, 3) polyp detection and classification in CT colonography, 4) separation of bones from soft tissue in chest radiographs, and 5) radiation dose reduction in CT and mammography.
