In my opinion I don't really see the essence of productid since it is the same as the product category , then i also don't understand this providerid very well.
Same here too.The fact that some labels are present in the training set and absent in the test makes it worse.
I don't think the two are the same
Check the Variables definition
Please try as much as possible to read the data variable definitions before you do anything to have a clew on what data is about.
ProductID is the name of the item being bought and ProductCategory is the category that the item falls into.
For example, ProductIDs could be car, truck, motorcycle but these 3 ProductIDs fit into the ProductCategory vehicles.
Does this make sense?
Hello AmyBray,yes it is
