 \section{Experimental Setup}
 
+This section explains the setup for the different conducted
+experiments. Each comparison investigates one particular question.
+
+As a baseline, vanilla SSD with the confidence threshold of 0.01
+and a non-maximum suppression IOU threshold of 0.45 was used.
+Due to the low number of objects per image in the COCO data set,
+the top \(k\) value was set to 20. Vanilla SSD with entropy
+thresholding uses the same parameters; compared to vanilla SSD
+without entropy thresholding, it showcases the relevance of
+entropy thresholding for vanilla SSD.
+
+Vanilla SSD was also run with 0.2 confidence threshold and compared
+to vanilla SSD with 0.01 confidence threshold; this comparison
+investigates the effect of the per class confidence threshold
+on the object detection performance.
+
+Bayesian SSD was run with 0.2 confidence threshold and compared
+to vanilla SSD with 0.2 confidence threshold. Coupled with the
+entropy threshold, this comparison shows how uncertain the network
+is. If it is very certain the dropout sampling should have no
+significant impact on the result.
+
+Both, vanilla SSD with entropy thresholding and Bayesian SSD with
+entropy thresholding, were tested for entropy thresholds ranging
+from 0.1 to 2.5 as specified in Miller et al.~\cite{Miller2018}.
