Speech Title: Deep Transfer Learning through Selective Joint Fine-Tuning
Abstract: Deep learning is a powerful machine learning paradigm that involves deep neural network architectures, and is capable of extracting high-level representations from multi-dimensional sensory data. Such high-level representations are essential for many intelligence related tasks, including visual recognition, speech perception, and language understanding. Deep neural networks require large amounts of labeled training data during supervised learning. However, collecting and labeling so much data might be infeasible in many cases. In this talk, I introduce a deep transfer learning scheme, called selective joint fine-tuning, for improving the performance of deep learning tasks with insufficient training data. In this scheme, a target learning task with insufficient training data is carried out simultaneously with another source learning task with abundant training data. Our core idea is to identify and retrieve a useful subset of training images from the original source learning task, and jointly fine-tune shared convolutional layers for both tasks. Experiments demonstrate that our deep transfer learning scheme based on selective joint fine-tuning achieves state-of-the-art performance on multiple visual classification tasks with insufficient training data for deep learning. Such tasks include Caltech 256, MIT Indoor 67, and fine-grained classification problems (Oxford Flowers 102 and Stanford Dogs 120).

Speech Title: An Elementary and Introductory Approach to Fractional Calculus and Its Applications
Abstract: The subject of fractional calculus (that is, calculus of integrals and derivatives of any arbitrary real or complex order) has gained considerable popularity and importance during the past over four decades, due mainly to its demonstrated applications in numerous seemingly diverse and widespread fields of science and engineering. It does indeed provide several potentially useful tools for solving differential and integral equations, and various other problems involving special functions of mathematical physics as well as their extensions and generalizations in one and more variables. The main object of this lecture is to present a brief elementary and introductory approach to the theory of fractional calculus and its applications especially in developing solutions of certain interesting families of ordinary and partial fractional "differintegral" equations. This general talk will be presented as simply as possible keeping the likelihood of non-specialist audience in mind.

Speech Title: Learning Control: Ideas and Problems in Adaptive Fuzzy Control
Abstract: Intelligent control is a promising way of control design in recent decades. Intelligent control design usually needs some knowledge of the system considered. However, such knowledge usually may not be available. Learning becomes a important mechanism for acquiring such knowledge. Learning control seems a good idea for control design for unknown or uncertain systems. To learn controllers is always a good idea, but somehow like a dream. It is because learning is to learn from something. But when there is no good controller, where to learn from? Nevertheless, there still exist approaches, such as adaptive fuzzy control, that can facilitate such an idea. It is called performance based learning (reinforcement learning and Lyapunov stability). This talk is to discuss fundamental ideas and problems in one learning controller -- adaptive fuzzy control. Some deficits of such an approach are discussed. The idea is simple and can be extended to various learning mechanisms. In fact, such an idea can also be employed in various learning control schemes. If you want to use such kind of approaches, those issues must be considered in your study
