Several different batch sizes $\mathcal{B} = \left\{ 2,4,6,8 \right\}$ and sample sizes $\mathcal{S} = \left\{ 2\mathcal{B}_i,4\mathcal{B}_i,5\mathcal{B}_i,10\mathcal{B}_i \right\}$
dependent on the selected batch size were selected.
We define the baseline (passive learning) AUC curve as the supervised learning process without any active learning.

Label-Studio provides a great api which can be used to update the predictions of the model from the dagster pipeline.
Overall this option should just be chosen if the solution needs to be scalable and deployed in the cloud.
For smaller projects a simpler solution just in an notebook or as a simple python script might be more appropriate.

This helps to keep track of the data and to rerun the pipeline with the same data.
\textit{train\_sup\_model} is the main asset that trains the model with the labeled samples.
\textit{inference\_unlabeled\_samples} is the asset that predicts the scores for the unlabeled samples und updates them with the Label-Studio API.

\subsection{Outline}\label{subsec:outline}
In section~\ref{sec:material-and-methods} we talk about general methods and materials used.
First the problem is modeled mathematically in~\ref{subsubsec:mathematicalmodeling} and then implemented and benchmarked in a Jupyter notebook~\ref{subsubsec:jupyternb}.
First the problem is modeled mathematically in section~\ref{subsubsec:mathematicalmodeling} and then implemented and benchmarked in a Jupyter notebook~\ref{subsubsec:jupyternb}.
Section~\ref{sec:implementation} gives deeper insights to the implementation for the interested reader with some code snippets.
The experimental results~\ref{sec:experimental-results} are well-presented with clear figures illustrating the performance of active learning across different sample sizes and batch sizes.
The experimental results in~\ref{sec:experimental-results} are well-presented with clear figures illustrating the performance of active learning across different sample sizes and batch sizes.
The conclusion~\ref{subsec:conclusion} provides an overview of the findings, highlighting the benefits of active learning.
Additionally the outlook section~\ref{subsec:outlook} suggests avenues for future research which are not covered in this work.

Finally Wald's theory of statistical decision functions is summarised and generalised and its relation to the theory of rational behaviour is discussed.},
