[交流] 【分享】QSAR竞赛:预测环境毒性(德国)

Environmental Toxicity Prediction Challenge

This challenge is organized by ICANN'09: International Conference on Artificial Neural  Networks, European Neural Network Society (ENNS) and CADASTER project.

Goals of this study:
Develop in silico models to predict environmental toxicity of molecules against T. pyriformis using data from [1].  Estimate the prediction intervals for new compounds. Further information can be found at http://www.cadaster.eu.

Five datasets of descriptors are available:
Quantum Chemistry, E-state, DRAGON, SimulationsPlus and MOE descriptors

Important key dates
August 31 The submission of results is closed.
September 14-17 2009 The winner will be announced at the ICANN'09 conference
(there is no requirement to participate to this conference)

The winner will be identified according to the criteria defined below. It is expected that the winner as well as other participants will submit articles describing their ethodological approaches  for publication in a peer-reviewed journal (under discussion).

Criteria for success
Firstly, methods with Root Mean Squared Error (RMSE) non-significantly  different to the method with lowest RMSE (according to the bootstrap test,  p<0.05) will be identified as the first-pass winners.
Secondly, the method providing the best likelihood criteria between estimated and
observed confidences for the blind test set as described in [2] will be identified amid the first-pass winners.

竞赛年年有,看看热闹吧。

要玩就玩个大的:
百万美元巨奖的Netflix比赛历时三年,终于在最近几天决出了最后的结果。http://www.netflixprize.com//leaderboard


BellKor's Pragmatic Chaos 在六月份率先达到10%的改进率,百万美元眼看就要到手!在30天的公示期内,第二名和第三名联合组成”The Ensemble “,于最后一天提交了比BellKor's Pragmatic Chaos更好的结果。很有戏剧性啊

不管是BellKor's Pragmatic Chaos ,还是 The Ensemble ,都是由多个团队联合起来的。
