TUTORIAL


Title: Immunological Computation: Theory and Applications

Speaker: Dipankar Dasgupta, The University of Memphis

Scope: The tutorial will be devoted to exploring different immunological mechanisms and their relation to information processing and problem solving. The natural immune system is an adaptive learning system which is highly distributive in nature. It employs several alternative and complementary mechanisms for defense against foreign pathogens. We will discuss different computational models based on immunological principles and their applications.

Overview: The natural immune system is a subject of great research interest because of its powerful information processing capabilities. The main purpose of the immune system is to recognize all cells (or molecules) within the body and categorize those cells as self or non-self. The non-self cells are further categorized in order to induce an appropriate type of defensive mechanism. The immune system learns through evolution to distinguish between foreign antigens (e.g., bacteria, viruses, etc.) and the body's own cells or molecules.

From an information-processing perspective, the immune system is a remarkable parallel and distributed adaptive system. It uses learning, memory, and associative retrieval to solve recognition and classification tasks. In particular, it learns to recognize relevant patterns, remember patterns that have been seen previously, and use combinatorics to construct pattern detectors efficiently. Also, the overall behavior of the system is an emergent property of many local interactions. These remarkable information-processing abilities of the immune system provide several important aspects in the field of computation. Artificial Immune Systems are used in pattern recognition, fault detection, computer security, and a variety of other applications.
