[jira] [Created] (MXNET-1359) Multiclass MCC metric for Python

Robert Stone created MXNET-1359:
-----------------------------------

             Summary: Multiclass MCC metric for Python
                 Key: MXNET-1359
                 URL: https://issues.apache.org/jira/browse/MXNET-1359
             Project: Apache MXNet
          Issue Type: Improvement
            Reporter: Robert Stone


A multiclass metric equivalent to {{mxnet.metric.MCC}} can be derived from {{mxnet.metric.PearsonCorrelation}} with the addition of an {{.argmax()}} on preds.  I'd like to document this use case of Pearson and provide it behind a metric named "PCC" to simplify extending examples from F1 and MCC to multiclass predictions.
