\newglossaryentry{Detexify}{name={Detexify}, description={A system used for
on-line handwritten symbol recognition which is described in \cite{Kirsch}}}

\newglossaryentry{epoch}{name={epoch}, description={During iterative training of a neural network, an \textit{epoch} is a single pass through the entire training set, followed by testing of the verification set.\cite{Concise12}}}

\newglossaryentry{hypothesis}{
    name={hypothesis},
    description={The recognition results which a classifier returns is called a hypothesis. In other words, it is the \enquote{guess} of a classifier},
