Interestingly, no extensive research that considers the influence of the ratio of active to inactive training examples on the efficiency of new active compounds recognition has been performed.
The figure presents ROC curves for 5-HT1A target illustrating the improvement of the machine learning models performance, calculated for several negative training example quantities (i.e. 100, 1000, 2000, 3000 and 4000) (A) and the dependence of AUC on the number of inactive training examples (B).
H3K27me3 and H3K9me3, repressive histone modification marks associated with poised enhancers in embryonic stem cells and heterochromatin [ 32, 33], respectively, were not detected at any of the identified p63 binding sites (Fig 2A), even though these marks are present at promoters of inactive genes (examples in Supplementary Fig S5A).
In studies of rats who were forced to be inactive, for example, he discovered that the leg muscles responsible for standing almost immediately lost more than 75 percent of their ability to remove harmful lipo-proteins from the blood.
The HEG domain is therefore still subject to weak selection pressure, even if it is inactive (for example stop codons and frame-shifts will be selected against).
On the contrary, higher income could lead to increased risk for overweight by giving opportunities to be inactive, for example, through television viewing.
Another possibility is that several transcription factors have potential binding sites upstream of a gene, but in females certain sites are inactive (for example through an epigenetic factor or a mutation) and in males others are inactive.
For example, the combined stimulation of the ER and NFκB pathways might affect NFκB dimerization and shift the balance of transcriptionally inactive dimers (for example, NFκB1/NFκB1) and active dimers (for example, RelA/NFκB1) in favor of the latter [ 69].
For example, "inactive" means not active; "inadmissible" means not admissible; "incapable" means not capable; "inseparable" means not separable; and on and on the examples could go.
Oftentimes, subjective measures of infrastructure are employed, leading to biased results, for example inactive people have a worse perception of the actual supply of facilities.
