Towards A Community of Machine Learners
Through Learning Online Communities of Practice
Motivation:
1. Social (Interaction) Networks grow from cyberspace
remarkably fast
with large scale participation and data
e.g. Email, Blog, Instant Messaging (IM), and the WWW

2. Machine Learning algorithms
current trend : highly optimized and tuned
perform well in many classification, clustering scenarios
e.g. kernel machines, ICA, LDA……

Towards A Community of Machine Learners
Through Learning Online Communities of Practice
AI
Human
NN, GA, Agent ……
web mining …any more
Motivation:
1. Social (Interaction) Networks grow from cyberspace
more underlying dynamics
how to improve so as to query,communicate conveniently
