Azure Machine learning: error with multiclass classification algo

I have training set and test set (csv files with header), in which I have to classify each value. There is 118.000 uniq values in X column, and only about 13000 in y1 column, so there will be 13000 categories.

enter image description here

From Training set I need only X and y1 column to train model. I need to classify X value to one of categories (find normal from of initial word). I tried all multi algo but failed trying to evaluate model.

Visualizing Score model return this:

What can be a problem, it just returns -2 code as error and this log

UPD1: By Metadata Editor module under Project Column Module made column y1 as categorical, nothing seems to be changed

Solution

  • Moncef provided here the solution to my problem:

    The point is that Azure has limitations on maximum categories 8192, this is why the number should be decreased by R or python modules or own evaluation module may be created. Or there is another way, evaluation step may be skipped, because model`ve been trained successfully.
