问题描述

我尝试使用该模块创建自己的实验，但未能使其正常工作.这是我得到的例外:

I tried to create my own experiment using the module, but failed to make it work. here is the exception i got:

我已经检查了我设置为输入用户地方评分表的输入数据，按记录记录(不用担心，它只有14条记录)，这里是:

i've check the input data i'm setting as input user-place-rating table, record by record (no worries it's only 14 records) here it is:

以下是实验的屏幕截图:

Here is a screenshot of the experiment:

由于错误消息不是很有意义，所以我不知道从哪里开始，所以，如果有人有想法，我将很高兴听到它.

since the error message is not very informative, I don't know where to start, so, if anybody has an idea, I would be happy to hear about it.

更新:我的一个朋友建议添加编辑元数据"模块，以将评级"功能更改为"int"或"float"类型，并将另外两个(placeID和userID)更改为字符串功能.那也没有帮助.

Update: A friend of mine suggested to add "Edit Metadata" module to change the "rating" feature into "int" or "float" types, and the two other(placeID and userID) into string features. that didn't help as well.

推荐答案

火柴盒推荐器要求等级为数字或分类.同样，在训练时，您的评分可能不会全部相同.

The matchbox recommender requires that ratings be numerical or categorical. Also when training, your ratings cannot all be the same.

您需要使用元数据编辑器 https://msdn.microsoft.com/en-us/library/azure/dn905986.aspx 要将等级转换为数字特征，则需要确保使用的等级范围.

You need to use a metadata editor https://msdn.microsoft.com/en-us/library/azure/dn905986.aspx to convert the ratings into numerical features and you need to make sure you are using a range of ratings.

那么这应该工作！
