保留Weka中交叉验证的订单 [英] Preserve Order for Cross Validation in Weka

问题描述

我正在使用Weka GUI对传感器数据进行分类。

我有10个人的度量，数据已排序。因此，前10％对应于参与者1，第二10％对应于参与者2，等等。

我想使用10倍交叉验证在9位参与者上建立模型并在其余的参与者上进行测试。就我而言，我相信我可以通过简单地不随机化数据拆分来实现这一目标。

我该如何最好地做到这一点？ div class = h2_lin>解决方案

我不知道如何在资源管理器中执行此操作。

在 KnowledgeFlow中 GUI，有一个 CrossValidationFoldMaker 用于创建交叉验证折叠。它具有保留实例顺序的选项，该选项表示保留实例的顺序而不是随机重排。

有一段视频描述了KnowledgeFlow界面：

I am using the Weka GUI for classifying sensor data.

I have measures of 10 people, the data is sorted. So the first 10% correspond to participant 1, the second 10% to participant 2 etc.

I would like to use 10 fold cross validation to build a model on 9 participants and test it on the remaining participant. In my case I believe I could accomplish this by simply not randomizing the data splits.

How would I best go about doing this?

解决方案

I don't know how to do this in the Explorer.

In the KnowledgeFlow GUI, there is a CrossValidationFoldMaker used to create cross-validation folds. This has an option to Preserve instances order, which says it preserves the order of instances rather than randomly shuffling.
