Just released a new version of the confusionmatrix Weka package that I started a while ago. I added a new heatmap visualization, which scale the rows by the sum of counts in that row. Essentially using percentages in a row, which is useful when you have skewed class distributions. Then the big class(es) don’t drown out the smaller (and potentially very important) class(es).
- Weka package
- Maven dependency you can find on the github project page
