Weka十进制精度 [英] Weka decimal precision

问题描述

在对我的定价数据使用Weka GUI中的MLP所带来的看似出色的结果感到非常兴奋之后，我编写了一些Java，使用了具有相同参数的MLP.这是乐趣的开始，结果是完全不同的，我现在发现这似乎是由于四舍五入的缘故. GUI舍入为3 dp，我的Java代码舍入为5 dp.

After getting very excited by what seemed like excellent results from using the MLP within the Weka GUI on my pricing data, I've coded up a bit of Java that uses an MLP with the same parameters. Here is where the fun starts, the results are completely different, I've now found that this appears to be be due to rounding differences. The GUI rounds to 3 dp, my java code rounds to 5 dp.

我已经仔细阅读了手册，但似乎找不到一个选项来强制GUI在其输出的谓词上使用5dp精度.有人知道我该怎么做吗?

I've looked through the manuals but I can't seem to find an option to force the GUI to use 5dp precision on the predicitions it outputs. Does anyone know how I can do this ?

谢谢

推荐答案

The Pentaho WEKA Forum says that the number of decimal places in the GUI is fixed. However, in writing the output from the GUI to a file, you can control the number of decimal places.
