\begin{frame}[allowframebreaks]{Papers approach}
|

\begin{itemize}
|
||||
\item kategorisieren von Variablen
|
||||
\item Based on complementary-representations of model
|
||||
\item Models of different size
|
||||
\item Different structural-bias $\rightarrow$ different category-wise performance
|
||||
\item Small model
|
||||
\begin{itemize}
|
||||
\item Variablen \textit{(int, char, double, float)}
|
||||
\item Pointer
|
||||
\item Arrays
|
||||
\item lower capacity
|
||||
\item better captures temporal dynamics in recognizing actions
|
||||
\end{itemize}
|
||||
\item Large model
|
||||
\begin{itemize}
|
||||
\item better learns spatial semantics
|
||||
\item to distinguish different action instances
|
||||
\end{itemize}
|
||||
\item Keyword \textit{struct}
|
||||
\item verbessert Übersicht
|
||||
\item Schritt Richtung Objektorientierung
|

\item ideal für Listen und Baumstruktur
