* * PG Day Presentation Zhili Wu Supervisor: Dr. Chunhung Li Cosupervisor: Prof. Jiming Liu 1/Oct/2004 ~ 10/Jan/2005 Towards A Community of Machine Learners Through Learning Online Communities of Practice Outline: 1. Introduction Motivation Objective Background Related Topics Tentative Proposals 2. Experimental Study BBS Data Study MATLAB Programming Contest Platform Study 3. Future Work 4. Q A 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? 2. Machine Learning algorithms can they show collective power rather than (over-)fitness? can they help (1), and benefit from their effort to (1)? Towards A Community of Machine Learners Through Learning Online Communities of Practice AI Human NN, GA, Agent …… web mining …any more???? Objective: Witness network (Internet) technology enabled social activities are powerful, massive, learnable, going virtual …… How can artificial learners like machine learners progress by getting inspiration from the social setting of online human learning? Towards A Community of Machine Learners Through Learning Online Communities of Practice More Specific Domain 1. Understand social interactions, mainly emphasize on online social interactions, through statistical and machine learning on data collected from online Communit
