Vertically align a multirow text which has been rotated

Question

I know using turn command and a sample code like this:

\usepackage{rotating}

\begin{turn}{90} Supervised Learning \end{turn}}

we can rotate a text inside a cell, however, I couldn't find a way to vertically center this rotated text when we have multirow. Any suggestions is appreciated.

\begin{table}
    \centering
    \caption{A Classification }
    \begin{tabular}{|c|>{\centering\arraybackslash}m{2.2cm}|>{\centering\arraybackslash}m{10.5cm}|}
        \hline
        \multicolumn{2}{|c|}{Classification} & References \\ \hline
        \multirow{2}{*}{{\begin{turn}{90}Supervised Learning\end{turn}}}   
       % \multirow{2}{*}{\rotatebox[origin=c]{90}{\parbox{.6cm}{\centering{Supervised Learning}}}}
