Title: Designing Effective Multi-objective Particle Swarm Optimization Algorithms

Presenter: A/Prof. K C Tan, National University of Singapore

Synopsis:
Multi-objective (MO) optimization is a challenging research topic because it involves the simultaneous optimization of several conflicting objectives in the Pareto optimal sense and requires researchers to address many issues that are unique to MO problems. Multi-objective particle swarm optimization (MOPSO) algorithm is a stochastic optimization technique that simulates the behavior of bird flocks to solve MO problems. The MOPSO algorithm is steadily gaining attention from the research community in evolutionary computation due to its fast convergence, which on the other hand, also gives rise to various design issues such as complexity and effectiveness. In this talk, a number of advanced features for MOPSO and co-evolutionary algorithms are proposed for handling large-scale optimization problems. A couple of industrial applications will also be presented.

Title: Autonomous Physical Interaction combining Vision, Tactile and Force Feedback

Synopsis:
The talk will be based on my latest book titled Robot Physical Interaction through the combination of Vision, Tactile and Force Feedback: Applications to Assistive Robotics, to be published in the Springer Tracts in Advanced Robotics (STAR) series, co-authored by Mario Prats and Pedro J. Sanz. This research was recipient of various awards, including the Georges Giralt European Award and the Robotdalen Scientific Award Honorary Mention.

Autonomous robot manipulation is one of the most important challenges in robotics. It involves three challenges: versatility, defined as the capability to adapt to different situations, instead of being limited to a particular task; autonomy, that concerns the level of independence in the robot operation, and dependability, that refers to the capability of successfully completing an action even under important modeling errors or inaccurate sensor information. A complete manipulation task involves two sequential actions: that of achieving a suitable grasp or contact configuration, and the subsequent motion required by the task. We propose a unified framework with the introduction of task-related aspects into the classical knowledge-based grasp concept, leading to task-oriented grasps. In a similar manner, grasp-related issues are also considered during the execution of a task, leading to grasp-oriented tasks. We call this unified representation physical interaction. In the talk I will first present a theoretical framework for the integrated specification of physical interaction tasks, supporting a great variety of actions. Next, the problem of autonomous planning of physical interaction tasks will be addressed. I will then focus on the dependable execution of these tasks, and adopt a sensor-based approach with three different types of sensor feedback: force, vision and tactile. The methods proposed provide important advances with respect to the state-of-the-art versatility, autonomy and dependability of robotic manipulation, allowing to address a wide range of tasks. All these contributions are validated with several experiments using different real robots placed on household environments.

Title: Evolutionary Computation techniques for Computer Vision

Synopsis:

Computer vision is an interdisciplinary field concerned with the automated processing and analysis of images from the real world. The applications range from simple edge detection tasks to complex robot vision tasks. Due to the large search space and noise environments, solving vision tasks has been very challenging. Over the last decade there has been increasing interest in using evolutionary computation techniques to solve vision problems. This talk will discuss how to use evolutionary techniques such as genetic programming and learning classifier systems to solve vision problems particularly image classification tasks. Three real world applications in automatic object tracking, motion detection and adaptive digit recognition will also be discussed. A key characteristic of this approach to these challenging problems is that one can usually obtain exciting results without needing to develop complex mathematical models.
