\begin{itemize}

\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}
|
\begin{itemize}
|
||||||
\item Variablen \textit{(int, char, double, float)}
|
\item lower capacity
|
||||||
\item Pointer
|
\item better captures temporal dynamics in recognizing actions
|
||||||
\item Arrays
|
\end{itemize}
|
||||||
|
\item Large model
|
||||||
|
\begin{itemize}
|
||||||
|
\item better learns spatial semantics
|
||||||
|
\item to distinguish different action instances
|

\end{itemize}

\end{itemize}
|

\item Keyword \textit{struct}
|

\item verbessert Übersicht

\item Schritt Richtung Objektorientierung
