posted May 19, 2016, 12:58 PM by Yanchang Zhao   [ updated May 20, 2016, 5:12 AM ]

The RDataMining group on LinkedIn has got 20,000 members.

Created in August 2011, the group received wide interest and expanded very quickly. In less than 5 years, its size reached 20,000.
It is now one of the top LinkedIn groups for data mining and data science. It is one of the fastest growing groups and one of the most active groups in above area (KDnuggets, 2015).

Thanks to all members for their contributions to the RDataMining group. As a big group on data mining and analytics, we will continue our journey of sharing knowledge and experiences in R and Data mining and will make our group better and better.

AusDM invites contributions addressing current research in data mining and knowledge discovery as well as experiences, novel applications and future challenges.

Submission of papers
- Academic submissions: Regular academic submissions can be made in Research Track reporting on research progress, with a paper length of between 8 and 12 pages in CRPIT style.
- Industry submissions: Submissions can be made in the Application Track to report on specific data mining implementations and experiences in governments and industry projects. Submissions in this category can be between 4 and 8 pages in CRPIT style.
- Industry Showcase submissions: Submission from industry and government on an analytics solution that has raised profits, reduced costs and/or achieved other important policy and/or business outcomes can be made in this track with a one page Abstract only.

Seminar on Cyberbullying Detection by Applying AI Approaches, University of Canberra, 4:30pm Tuesday 2 Feb 2016

posted Jan 27, 2016, 12:39 AM by Yanchang Zhao   [ updated Jan 27, 2016, 12:39 AM ]

Topic: Cyberbullying Detection by Applying AI Approaches
Speakers: Prof. Chengqi Zhang and Dr. Guodong Long, University of Technology, Sydney
Organisers: The Canberra Data Scientists group and the Information Technology & Engineering Program, University of Canberra
Date and time: 4:30-6:00pm, Tuesday, 2 February 2016
Location: Teal Room, Inspire Centre (Building 25 on the map at http://www.canberra.edu.au/maps/campus-map)

Abstract:
Cyberbullying is the use of technology to bully a person or group with the intent to hurt them socially, psychologically or even physically.  Currently there are many young people being cyberbullied or involving in cyberbullying activities, and the cyberbullying offence has been defined as criminal activity by law. To avoid the severe results (e.g. spirit trauma, or be charged as criminal), cyberbullying detection emerged to real-time proactively prevent cyberbullying by generating early warning. Most studies on Cyberbullying detection focus on key-words search and sentiment filtering on textual contents. All of them neglects the online conversation's rich context information including texts, networks, time and demographics. In this talk, we will introduce a novel solution for applying AI approaches to detect cyberbullying by exploiting rich heterogeneous context information.

Biography:
Prof. Chengqi Zhang is a Research Professor of Information Technology at The University of Technology Sydney (UTS), an Honorary Professor of the University of Queensland (UQ), Director of the UTS Priority Research Centre for Quantum Computation & Intelligent Systems (QCIS). He is Alternative Dean of UTS Graduate Research School, Chairman of the Australian Computer Society National Committee for Artificial Intelligence and Chairman of IEEE Computer Society Technical Committee of Intelligent Informatics (TCII). Chengqi Zhang obtained his PhD degree from the University of Queensland in 1991, followed by a Doctor of Science (DSc – Higher Doctorate) from Deakin University in 2002. His key areas of research are Distributed Artificial Intelligence, Data Mining and its applications. He has published more than 200 refereed research papers and six monographs and edited 16 books. He has attracted 12 ARC grants of $4.7M. He is a Fellow of the Australian Computer Society (ACS) and a Senior Member of the IEEE Computer Society (IEEE).

CIKM Machine Learning Competition 2015

posted Jul 28, 2015, 12:29 PM by Yanchang Zhao   [ updated Jul 28, 2015, 12:29 PM ]

The CIKM Machine Learning Competition 2015 is centered around the AFL. Participants are required to predict the outcomes of every match in the 2015 AFL season in two phases:

- the Leaderboard phase, where contestants predict the outcome of each regular-season match in the 2015 AFL season. The corresponding leaderboard will be updated as the season progresses. This phase will be based on an honour system since the results of matches will already be known.

- the Finals phase, where contestants predict the outcome of each match in the 2015 AFL Finals Series. Submissions will close prior to the commencement of the first finals series match. The final leaderboard of the competition will be determined from these matches and a competition winner will be annonced after the 2015 AFL Grand Final.

The winner of the competition will be awarded $5,000 (AUD) and will be required to provide a satisfactory description of their approach.

Competition opens: 24 July 2015
Submissions close: 10 Sept 2015
