I have a learning problem from $X$ to $Y$ where:
- $X$ = $n$ input numeric vectors of $m$ dimensions
- $Y$ = $n$ output numeric vectors of $k$ dimensions
In other words:
I am hoping to collect a list of R packages or Python libraries for multiple-output problems for classification and regression.
For example, do any of the learning methods in caret support this functionality? What packages in general are available for this problem?
