BlogTalk 2003 |
| Abstract |
This talk is an introduction to the Semantic
Blogging notion to a blogging community. Phrased in the
informal blogTalk style: "My thesis takes the form
"Blogging is cool - but it could be even cooler. How?
Semantic Blogging, that's how!" |

| Title |
Immune Systems - an evolutionary
metaphor |
| Date |

| Abstract |
Immune systems provide a rich biological
metaphor. They can be viewed as autonomous, distributed and
adaptive systems which exhibit a range of desirable
characteristics for machine learning. One way (not the only
way) of implementing artificial immune systems (AIS) is to use
evolutionary techniques. In this talk I shall pursue the
implications of this approach for AIS research. In order to
motivate the discussion, an example system will be described -
a co-evolutionary immune system for document classification.
This talk will assume no previous knowledge of artificial
immune systems. |

A
Recommender System based on the Immune
Network |

| Abstract |
The immune system is a complex biological
system with a highly distributed, adaptive and self-organising
nature. This talk presents an artificial immune system (AIS)
that exploits some of these characteristics and is applied to
the task of film recommendation by collaborative filtering
(CF). Natural evolution and in particular the immune system
have not been designed for classical optimisation. However, for
this problem, we are not interested in finding a single
optimum. Rather we intend to identify a sub-set of good matches
on which recommendations can be based. It is our hypothesis
that an AIS built on two central aspects of the biological
immune system will be an ideal candidate to achieve this:
Antigen - antibody interaction for matching and antibody -
antibody interaction for diversity. Computational results are
presented in support of this conjecture and compared to those
found by other CF techniques. |
