Sentence examples for class ratio from inspiring English sources

As can be seen in Table 1 the data sets vary in terms of size and class ratio.

This means that standard techniques, which assume equality, are not very effective at building predictive models when there is a low minority class ratio.

In all instances, the performance of the classifiers would have been reduced if minority class ratios had been used as the Weka misclassification cost - there are significant differences between the optimal cost and the class ratio cost.

This analysis was conducted for targets encompassing a good number (more than 1000) of inactives, which still require additional SE sampling of compounds to gain the 1 100 class ratio.

While the benign-malicious class ratio for PDF is approximately equal throughout all time periods, the distribution of malicious and benign SWF files in time is highly skewed, as visible in Figs. 13 and 14.

- Academics Professor Availability Popular Programs Average Size of Class (ratio to student) Possible Internships Study Abroad Opportunities Available Technology Library Facilities.

This illustrates that the setting of the Weka misclassification cost is arbitrary and more closely linked to the base classifier used than the class ratios or the number of attributes.

Care when using Weka's cost-sensitive classifiers is needed - across the board misclassification costs based on class ratios should not be used when comparing differing classifiers for the same dataset.

As the costs we are discussing are the actual settings of the Weka cost matrix rather than class ratios, the comparison of classifiers cannot be compared using cost curves [13].

Notably, variation was also identified in two distinct processes during stomatal differentiation (primary and satellite lineage initiation), which can be hidden under stomatal abundance trait values, because accessions with a similar SI could have very different lineage class ratios.

Accessions with similar stomatal indices showed different lineage class ratios, revealing hidden developmental phenotypes and showing that genetic determinants of primary and satellite lineage initiation combine in several ways.
