To promote research on preferences in the search and machine learning communities, Live Labs is releasing new anonymized data from a project we did last year.  The Picture This game randomly pairs two users in a game setting.  The game selects queries, then the players are shown two or more images.  They [...]]]> http://blog.zye.me/2009/03/50497.html/feed 0 http://blog.zye.me/2009/02/49794.html http://blog.zye.me/2009/02/49794.html#comments Thu, 26 Feb 2009 22:59:14 +0000 jeffye http://blog.so8848.com/2009/02/49794.html BM family weighting scheme Introduction and important Literatures

里面推荐很多书的确非常经典，其中我看过的有两本，1. Stanford的那本《Introduction to Information Retrieval》 2. Bishop, 《Pattern Recognition and Machine Learning》，非常值得一读，网上都能找到电子版的，如果实在找不到给我留言。《Introduction to Information Retrieval》在我以前的post中已经给出下载链接，另外一本电子太大没地方能上传。

我经常在 TopLanguage 讨论组上推荐一些书籍，也经常问里面的牛人们搜罗一些有关的资料，人工智能、机器学习、自然语言处理、知识发现（特别地，数据挖掘）、信息检索 这些无疑是 CS 领域最好玩的分支了（也是互相紧密联系的），这里将最近有关机器学习和人工智能相关的一些学习资源归一个类：

首先是两个非常棒的 Wikipedia 条目，我也算是 wikipedia 的重度用户了，学习一门东西的时候常常发现是始于 wikipedia 中间经过若干次 google ，然后止于某一本或几本著作。

第一个是“人工智能的历史”（History of Artificial Intelligence），我在讨论组上写道：

而今天看到的这篇文章是我在 wikipedia 浏览至今觉得最好的。文章名为《人工智能的历史》，顺着 AI 发展时间线娓娓道来，中间穿插无数牛人故事，且一波三折大气磅礴，可谓”事实比想象更令人惊讶”。人工智能始于哲学思辨，中间经历了一个没有心理学（尤其是认知神经科学的）的帮助的阶段，仅通过牛人对人类思维的外在表现的归纳、内省，以及数学工具进行探索，其间最令人激动的是 Herbert Simon （决策理论之父，诺奖，跨领域牛人）写的一个自动证明机，证明了罗素的数学原理中的二十几个定理，其中有一个定理比原书中的还要优雅，Simon 的程序用的是启发式搜索，因为公理系统中的证明可以简化为从条件到结论的树状搜索（但由于组合爆炸，所以必须使用启发式剪枝）。后来 Simon 又写了 GPS （General Problem Solver），据说能解决一些能良好形式化的问题，如汉诺塔。但说到底 Simon 的研究毕竟只触及了人类思维的一个很小很小的方面 —— Formal [...]]]> http://blog.zye.me/2008/11/43780.html/feed 0 http://blog.zye.me/2008/08/39116.html http://blog.zye.me/2008/08/39116.html#comments Wed, 06 Aug 2008 07:49:06 +0000 jeffye http://www.5yiso.cn/2008/08/39116.html 信息检索领域相关资料
