The use of PCA enhanced the best average classification accuracies of BP and SVM. Figure 3 shows the average variation in classification accuracies versus the number of principle components with respect to various classifiers.
The parameter optimized in the character extraction step is the number of principle components passed to the subsequent steps.
In the future, community-based research focusing on principles of resource management should employ some means of detecting an asymptote in the number of new principles identified during interviews, similar to the sampling designs used by ecologists to estimate the number of undiscovered species in an ecosystem (e.g., Chao et al. 2009).
We did not see any gender-based differences in the number of natural selection principles used in the pretest (z = 0.49, p = 0.6243) or post test (z = −1.202, p = 0.23).
Instructors 1-AL and 2-AL showed substantial gains in the number of students demonstrating principle-based reasoning, whereas Instructor 3-MAL's students remained stable at a mixed reasoning level.
Microarrays can differ in the way the probes are attached to the surface, in the length of the probes and in the number of probes per gene, but the principle is always the same.

The surge in the number of candidates must raise questions about the principle of state funding of political parties, squalid though the alternative sometimes appears.
Since the Oslo signing of the Declaration of Principles in September 1993, the number of Israeli settlers in the West Bank has tripled, from 110,066 to over 340,000 today, plus approximately 200,000 settlers in East Jerusalem, where thousands of new housing units are continuously being built.
In principle, the number of reads that assemble in a specific contig represents the abundance of mRNA produced by a particular gene in a given tissue sample.
