title: Data Streaming based on Affinity Propagation; Application to Autonomic Computing
abstract: Affinity Propagation, a recent clustering algorithm based onmessage propagation techniques, yields quasi-optimal and stablesolutions at the price of a quadratic complexity. Two extensions will bedescribed, one for reducing the complexity and the other for dealingwith online clustering (data streaming). The talk will describe theapplication of StrAP to Autonomic Grid. The EGEE grid system involvesabout 80,000 CPUs, and concurrently processes 300,000 jobs on a 24 hour,7 day basis. The StrAP algorithm provides an online summary of the jobdistribution, amenable to the prompt detection of anomalies.

title: Crossing the Chasm for Evolutionary Algorithms
abstract: One drawback of Evolutionary Algorithms, preventing their wideuse outside the Evolutionary Computation community, paradoxically comesfrom their high flexibility. The large number of parameters EAs offer tothe user does indeed make them difficult to fine tune. This talk willsurvey the current state of research in the area of parameter tuning,both off-line and on-line, focusing on the continuous optimization case,where on-line adaptation provides state-of-the-art algorithms.
