\begin{itemize}
\item Supervised learning
\begin{itemize}
\item Data samples
\item Target labels
\item Each sample is associated to target label
\end{itemize}
\item Unsupervised learning
\begin{itemize}
\item Data samples
\item target is to find patterns in data
\item without supervision
\end{itemize}
\item Semi-Supervised learning
\begin{itemize}
\item combination of both
\item have labeled \& unlabeled data
\item labeled data guides learning process
\item unlabled helps to gain additional information
\item goal is performance improvement

\item Pseudo-labeling
\item Train model on labeled data

\item Eg. 1\% of data labeled

\item Confidence of prediction
\item If high enough
\item Use to predict unlabeled data

\item quantity and quality of pseudo-labels
\item significant impact on main model accuracy!
\item we want to improve pseudo-label framework as much as possible

\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
\end{itemize}

\item Pfeilnotation (->) wenn struct Pointer
\item Gesamtlänge der Struktur: sizeof(<Struktur>)
\item Weiteres hinzufügen von Komponenten während der Laufzeit nicht möglich.
\item Cross-Model Pseudo-Labeling
\item Primary backbone
\item Supplemented by lightweight auxiliary network

\item Different structure
\item Fewer channels

\item Different representation of data complements primary backbone
