I have the following LaTex code:
\begin{figure}[H]
\begin{subfigure}[b]{0.2\textwidth}
\includegraphics[width=\textwidth]{imgs/high_accuracy_Low_precision.png}
\caption{low accuracy, low precision}
\end{subfigure}
%
\begin{subfigure}[b]{0.2\textwidth}
\includegraphics[width=\textwidth]{imgs/high_precision_Low_accuracy.png}
\caption{low accuracy, high precision}
\end{subfigure}
\label{fig:4foldcross}
\end{figure}
The output result is:

How can I make some space in between these images?
