Subject [jira] [Created] (MXNET-1399) Improve Multiclass MCC metric for Python
Date Fri, 03 May 2019 22:53:00 GMT
Robert Stone created MXNET-1399:
-----------------------------------

             Summary: Improve Multiclass MCC metric for Python
                 Key: MXNET-1399
                 URL: https://issues.apache.org/jira/browse/MXNET-1399
             Project: Apache MXNet
          Issue Type: Improvement
            Reporter: Robert Stone


I noticed that [https://github.com/dmlc/gluon-nlp/blob/master/scripts/text_classification/fasttext_word_ngram.py]
uses mx.metric.Accuracy() in a way that would break the Multiclass MCC metric, so this should
be improved.

I also got feedback that PCC was a poor choice of names for this metric because users of MXNet
care that it is the multiclass extension of Mathews CC, so "mMCC" seems less obscure.
