\title{Confusion matrix callback.}
\usage{
conf_matrix_cb(path_tensorboard, run_name, confMatLabels, cm_dir)
}
\arguments{
\item{path_tensorboard}{Path to tensorboard directory or \code{NULL}. If \code{NULL}, training not tracked on tensorboard.}

\item{run_name}{Name of the run. Name will be used to identify output from callbacks. If \code{NULL}, will use date as run name.
If name already present, will add \code{"_2"} to name or \code{"_{x+1}"} if name ends with \verb{_x}, where \code{x} is some integer.}

\item{confMatLabels}{Names of classes.}

\item{cm_dir}{Directory that contains confusion matrix files.}
}
\value{
Keras callback, plot confusion matrix in tensorboard.
}
\description{
Create a confusion matrix to display under tensorboard images.
