7.2H, the consensus partition yielded by the multiple criteria–based WCE is very close to the ground truth in Fig. 7.2A. As a classic approach, cluster ensemble (CE) (Strehl and Ghosh, 2003) treats all partitions equally during reconciling input partitions. When applied to this data set, ...
where SM and GT represent the segmentation method and the ground truth, respectively [12, 25,26,27]. Besides, to assess the robustness of different methods, the test–retest reproducibility of the metrics between two different initial tumor masks (TRTMetrics) was calculated as: TRTMetrics=Metrics...
When there are two, diametrically opposed viewpoints in medicine or science, either one (or both) is (are), by definition, wrong. Assuming that one view is right, and that the other is wrong, a compromise between the two will move away from truth. So when true consensus does not exist...
Special attention was paid to the non-trivial implementation of the HLUT specification procedure itself (Step 5), which includes linear regression fitting in different tissue groups and the definition of the respective CT number intervals. For the latter, DECT-obtained body-region-specific tissue ...
To quote from the journal's mission statement, "Experimental Mathematics was founded in the belief that theory and experiment feed on each other, and that the mathematical community stands to benefit from a more complete exposure to the experimental process." Does mathematical truth really exist, ...
By applying an experiment-specific random transforma- tion to the source ellipsoids, we obtain N target ellip- soids, representing the ground-truth ellipsoid pair corre- spondences. To assess robustness, we generate test corre- spondences by adding different levels of noise to the point 3https...
Definition 4A strong embedding,MathML, is an embedding for whichMathML. In other words, a strong embedding is defined as one which accurately preserves the triangle relationship for more than some significant fraction (θ) of the unique triplets of objectsc,d,e∈Cthat exist. An embeddingℝn...
The truth is that majorities don’t just rule, they also influence. We can’t count on one or two lone voices having the courage to speak up. That’s why it’s not enough to simply listen to dissenting views, we must actively seek them out. ...
For each dataset we run our PCC-KL and PCC-ℓ 2 algorithms with the purpose of recovering the ground truth soft partition Y ∗. Although the optimal number of clusters is K=4, we run our algorithms with a larger value of K=8. This is not a problem as our formulation can automatic...
In each run the two algorithms are applied and the dis- tance between the obtained principal symmetry plane and the ground truth is measured. While several symmetry measures have ben proposed [8,9], we are not really interested in knowing how much the found symmetry diverge from a perfect ...
