 Labeling datasets is commonly seen as an expensive task and wants to be avoided as much as possible.\cite{generalAI}
 That's why there is a machine-learning field called active learning.
 The general approach is to train a model that predicts within every iteration a ranking metric or Pseudo-Labels which then can be used to rank the importance of samples to be labeled by an oracle.
-These labeled are then used to train the model.\cite{activelearning}
+These labeled samples are then used to train the model.\cite{activelearning}
 
 The goal of this practical work is to test active learning within a simple classification task and evaluate its performance.

 First the problem is modeled mathematically in~\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.
