<p>
When you use the <code>OutputDataConfig</code> object while creating a custom classifier, you specify the Amazon
S3 location where you want to write the confusion matrix and other output files. The URI must be in the same
Region as the API endpoint that you are calling. The location is used as the prefix for the actual location of
this output file.
</p>
<p>
When the custom classifier job is finished, the service creates the output file in a directory specific to the
job. The <code>S3Uri</code> field contains the location of the output file, called <code>output.tar.gz</code>. It
is a compressed archive that contains the confusion matrix.
