Subject: APLAS'03

Call for Papers
The First Asian Symposium on
Programming Languages and Systems (APLAS'03)
Beijing, China. October 27-29, 2003
Sponsored by the Asian Association for Foundations of Software (AAFS) and Bei
hang University (Beijing University of Aeronautics and Astronautics) 

--------------------------------------------------------------------------------


Description
APLAS aims at stimulating programming language research by providing a forum 
for the presentation of recent results and the exchange of ideas and experien
ce in topics concerned with programming languages and systems. APLAS is based
 in Asia, but intends 
to be an international forum that serves the worldwide programming languages 
community. 
The APLAS series is sponsored by the Asian Association for Foundation of Soft
ware (AAFS), which has recently been founded by Asian researchers in cooperat
ion with many researchers from Europe and the USA. APLAS has been discussed a
nd prepared through 
informal workshops held in Singapore (2000), Daejeon (2001), and Shanghai (20
02). APLAS03 will be the first formal symposium in the series. 

Topics
The symposium is devoted to foundational issues in programming languages and 
systems, covering the following areas: 
semantics and theoretical foundations 
type systems and language design 
compilers and implementation 
program analysis and security 
program transformation and calculation 
concurrency

Subject: 关于数据预处理~`

mlchina2，您好！
当数据有缺损时，需要在数据预处理时进行必要的修补。我想知道有些什么修补的方法？
如果是取属性中出现频率较多的值作为修补值，那么这一出现频率多少是在整体样本中统
计，还是
在分好类的子样本中进行统计？本人是想进行决策树方面的尝试。

Subject: Re:关于数据预处理~`

如果我没记错的话
C4.5决策树程序里没有对缺损的数据进行修补

在构造决策树中，计算information gain都是基于有值的样本进行统计（某属性没值的i
nstance在计算该属性的information gain时不予考虑）

在分类时，属性值未知的样本 在遇到对该属性进行判别的结点时,将同时被分到决策树两
个分支里，最后根据最后决策权值决定到底属于哪类

比如，决策树在node的规则为 if A>a1 分支T1
else 分支T2
那么对于在属性A上缺值的样本将同时被分到分支T1和T2中去


不知道直接对未知属性预处理填补全了，分类效果如何。

Subject: Re:Re:关于数据预处理~`

张丽新,您好！

1。如果两百个样本中，某些属性缺失数值达到将近100个呢？这样使用决策树还有意义嘛？
2。你局的那个关于同时分配到两个分支的例子我看不懂，我觉得有缺失的样本还是应该
分到分支二呀？
3。发现自己对决策树的具体操作还是有理解上的缺乏，希望推荐几篇文章或者书籍能让
我更详细的理解决策树算法。
谢谢：）

Subject: 最小二乘线性拟合算法程序

大家好, 不知有谁了解用Matlab进行
最小二乘线性拟合的操作? 即求矩阵B和向量C,
使对于一组给定的向量对(Xi,Yi),i=1,2...M,
以下线性拟合式: Y=BX+C的平方误差最小, 能告诉我具体
方法么? 有源程序么?

谢谢!

Subject: 海量数据的分类问题 

请教大家个问题：

分类问题：数据集很大，每项数据（instance）的特征大约为30~40，或者更少些，而分
类就是为了数据判断正常异常，两类数据分类问题。请问在处理大数据量分类问题的时候
，那个算法比较合适，要求分类模型算法复杂度不能太高，还要考虑近实时性问题。支持
向量机在这样的情况下
