Sentence examples for by the symmetric difference from inspiring English sources

where the derivative operation is approximated by the symmetric difference.

The idea which these share in common is that the distance between two propositions is measured by the symmetric difference of the two sets of possibilities.

This approach provided for every dataset two gene lists with the intersect representing agreement and the symmetric difference representing different biological interpretations, which are solely caused by the different noise models (cf. Table 2, columns 'Comm. genes' and 'Diff. genes').

Note that in dealing with general sets one has to replace the Hausdorff distance with the weaker one given by the measure of the symmetric difference between a translated of the set E and B. This is unavoidable if one thinks that by adding to B some long thin spikes the volume and the perimeter of the resulting set change very little while its Hausdorff distance from B goes to infinity.

We achieve the automation assisted by the Boolean polygon operations, specifically using the symmetric difference operation.

To assess the fidelity with which individual genes recovered the reference tree on a holistic scale, we calculated the topological distance between each individual gene tree and the concatenated tree using the Symmetric Difference [ 30] computed by the TreeDist program included in the Phylip v3.68 package [ 31].

We address this problem by not permitting the use of Eppstein's method if the symmetric difference definitively exceeds (frac {n - mathcal {L}}{2}), where n is the smaller of the two set sizes.4 Instead, once the estimate of the symmetric difference substantially exceeds this threshold, the reconciliation algorithm falls back to sending the complete set.

We used the symmetric difference between trees to evaluate the accuracy of the different tree construction methods analyzed here.

(More precisely, if for any ε > 0, there is a finite union of basic sets F such that the symmetric difference between E and F can be covered by a set of measure less than ε. The symmetric difference is the set of elements which are in exactly one of E and F; it is the 'mismatch' between the two sets).

The symmetric difference of two sets A and B, denoted by AΔ B, is the set (A\ B) ∪ (B\ A).

This was followed by a second step in which a custom Perl script was used to derive the symmetric difference of the two parental SNP sets.
