+\section{Introduction}
+Today's use of \textit{recommender systems} finds an increased and yet unconscious access to our everyday life.
+More and more areas of life are therefore subject to constant optimisation.
+Companies such as \textit{Netflix}, \textit{Amazon} and \textit{YouTube} adapt their product proposals to the individual wishes of their customers.
+To make this possible, the various \textit{collaborative-filtering} and \textit{content-based} \textit{recommender systems} are used.
+
+Since \citet{JuKa90} first presented \textit{recommender systems} as a kind of intelligent bookcase, much effort has been put into the development and research of such systems.
+The most diverse subject areas were not only illuminated by the industry.
+ A whole new branch of research also opened up for science.
+
+ In their work ``On the Diffculty of Evaluating Baselines A Study on Recommender Systems`` \citet{Rendle19} show that current research on the \textit{MovieLens10M} dataset leads in a wrong direction.
+ In addition to general problems, they particulary list wrong working methods and missunderstood \textit{baselines} by breaking them by a number of simple methods such as \textit{matrix-factorization}.
+
+ They were able to beat the existing baselines by not taking them for granted.
+ On the contrary, they questioned them and transferred well evaluated and understood properties of the baselines from the \textit{Netflix-Challenge} to them.
+
+As a result, they were not only able to beat the \textit{baselines} reported for the \textit{MovieLens10M}, but also the newer methods from the last 5 years of research. Therefore, it can be assumed that the current and former results obtained on the \textit{MovieLens10M} dataset were not sufficient to be considered as a true baseline. Thus they show the community a critical error on which can be found not only in the evaluation of \textit{recommender systems} but also in other scientific areas.
+
+As a first problem, the authors point out that scientific papers whose focus is on better understanding and improving existing \textit{baselines} do not receive recognition because they do not seem innovative enough. In contrast to industry, which tenders horrendous prizes for researching and improving such \textit{baselines}, there is a lack of such motivation in the scientific field. From the authors point of view, the scientific work on the \textit{MovieLens10M} dataset is misdirected, because one-off evaluations leading to one-hit-wonders, which are then used as a starting point for further work. Thus \citet{Rendle19} points out as a second point of criticism that the need for further basic research for the \textit{MovieLens10M} dataset is not yet exhausted.
+
+This submission takes a critical look at the topic presented by \citet{Rendle19}. In addition, basic terms and the results obtained are presented in a way that is comprehensible to the non-experienced reader.
