The phrase "a fraction of features" is correct and usable in written English.
It can be used when discussing a small part or subset of features in a product, system, or concept.
Example: "The new software update includes only a fraction of features that were promised in the initial release."
Alternatives: "a small number of features" or "a limited set of features."
They may buy the latest digital camera, but end up using only a fraction of its features, or they may proudly tote an iPhone but still pay their bills by check, rather than online.
A fraction of these features is eliminated at each iteration.
The Mac version of Windows Media Player has only a fraction of the features of the one for Windows.
Furthermore, our FS algorithms allow us to build more cost-efficient classifiers which outperform baseline classifiers while only using a fraction of the features.
A gigabyte is also 2,000 half-megabyte digital photos and roughly 300 three-minute MP3 songs, but just a fraction of a feature-length film.
When a high fraction of features, ν > 0.5, is taken as differentially expressed the difference between the DFC test and t-test is minimal, as both tests remove the most easily detectable, non-expressed features.
Normalization methods for mRNAs often rely on one or more of the following assumptions: only a small fraction of features are differentially expressed and the proportions of up- and down-regulated expressions are approximately equal.
To select significant features from FDAFSA, we trained our model using a different fraction of features than the hexamer_set k of training_data k and tested our model with test_data k. Figure 1 shows the average sensitivities and specificities of different fractions of 4,096 features.
As discussed previously, unlike mRNA datasets, where it has been well established that only a small fraction of features can be differentially expressed; for miRNA datasets, we could not favor, a priori, any region of (0,1) for ξ →, because the proportions of differentially expressed features among different miRNA datasets could vary dramatically.
When a very small fraction of features ν ~ 1/ Np is taken as differentially expressed, resulting in only few features selected, the difference between the DFC test and t-test will be small again, as the differential expression of the few features should be very strong and can be effectively selected by t-test alone.
