This section giv \section{Findings} \label{sec:Evaluation:Findings} -\subsection{Choosing smd} +\subsection{Choosing tc} -The data confirms \hyporef{hyp:Evaluation:LowSMD} and \hyporef{hyp:Evaluation:HighSMD}. \autoref{fig:Evaluation:HappyUnhappySMD} shows a clear trend where with a higher $smb$ the amount of satisfied and dissatisfied is reduced. However, with homogenous group the dissatisfaction is constantly at zero and the satisfaction only takes a slight dip. This suggests that with homogenous groups an individual deciding for the whole group is a viable option. Random groups are more uniform than heterogeneous groups. This can be seen by a lower amount of dissatisfied group members and a higher amount of satisfied ones. - -\hyporef{hyp:Evaluation:MoreSatisfiedLessIncrease} states that the amount of hapiness increase should be limited if we choose a low $smb$ because there is less people that can be changed to satisfied. This effect however is not observable in the data even when $smb = 5$. Neither can the adverse effect with a high $smb$ and dissatisfaction change. Yet it might be possible that this effect can be observed when choosing $smb > 35\%$. The effects of \hyporef{hyp:Evaluation:OnePersonSatisfied} can also not be seen in the data. Moreover the effect of \hyporef{hyp:Evaluation:NoOnedissatisfied} could also not be seen in the data but it was noticeable that a high $smb$ reduces unhappiness reduction. Nonetheless these effects still might occur when testing a higher $smb$ than $35\%$. - -The $smd$ will be fixed from now on to $15\%$. This allows to still show the improvements of the recommender for rather heterogeneous groups but also prevents a too high reduction in dissatisfied group members thereby preventing any effect when just looking at dissatisfaction. As \autoref{fig:Evaluation:HappyUnhappySMD} shows homogenous groups are already too happy and have no dissatisfaction. This is why they will not undergo any more evaluation. +To get an understanding of the data all parameters except the $tc$ will be fixed. The preference aggregation strategy looked at is multiplication. The configuration database is used with all possible solutions (which is 148 in total). This results in a bigger visible effect as the recommender has access to all possible configurations. \begin{figure} \centering - \includegraphics[width=1\textwidth]{./figures/60_evaluation/smd_chamge_happy_unhappy.pdf} - \caption{The average satisfaction and dissatisfaction over the individual decision depending on \textbf{group type} and $smd$.} - \label{fig:Evaluation:HappyUnhappySMD} + \includegraphics[width=1\textwidth]{./figures/60_evaluation/tc_change__multi__db-size-148.pdf} + \caption{The average satisfaction and dissatisfaction change based on $tc$ with a database size of 148 and multiplication as aggregation strategy.} + \label{fig:Evaluation:tcChange} +\end{figure} + +\begin{figure} + \centering + \includegraphics[width=1\textwidth]{./figures/60_evaluation/tc_dictator__multi__db-size-148.pdf} + \caption{The average satisfaction and dissatisfaction with the dictator's decision based on $tc$ with a database size of 148 and multiplication as aggregation strategy.} + \label{fig:Evaluation:tcCount} \end{figure} \subsection{Analysing Data} diff --git a/Additional_Notes/analysis_tc.ods b/Additional_Notes/analysis_tc.ods new file mode 100644 index 0000000..68d9833 --- /dev/null +++ b/Additional_Notes/analysis_tc.ods @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:4ddb45d16ac539fb2c4dd3713506d349b4e6e623156c6b743ac31ca428022d98 +size 41366
