Such huge disproportion of positives and negatives instances determines a very high sparsity of the problem (density is less than 0.005), thus making the recommendation task particularly hard to solve with high accuracy.
Decision problems are typically specified in the form of questions about a class of mathematical objects whose positive instances determine the set in question – e.g. \(\sc{SAT}\ \) Given a formula \ \phi\) of propositional logic, does there exist a satisfying assignment for \ \phi\)?
The SRE consists of two copies of the half-site AG(G/T T(C/G A, with the number, spacing, and orientation of these motifs in many instances determining the specificity and strength of the response element.
Conveniently, the compatibility of the individual blocks in block copolymers can be studied via their thermal properties [ 12, 40– 43], as for instance, determined by DSC.
For instance, determining which genes are turned on in tumor cells but not in healthy cells could provide valuable clues to how cancer arises.
"If there is some program that, for instance, determines cardiac rhythm, it is not a separate [controlling] thing, it is the interaction between the cell proteins and the cell's electrical potential.
Because it will have direct communication with members, it also hopes to be able to improve the service based on their feedback — for instance, determining the best flight times for its users.
For instance, determining a patch of colour as "blue" does not consist in identifying some blue property or some blueness shared by blue things, but in differentiating this patch from the "other," namely from things that are not-blue.
Blue River Technology, which uses robotics and computer vision to optimize agriculture by, for instance, determining which lettuces to thin out of a row and which to keep, has closed a $10 million Series A-1 funding round, led by Data Collective Venture Capital — topping up a $3.1 million Series A it raised back in 2012.
For instance, determining the independent roles of neurotransmission and spiking on various forms of plasticity has proven challenging since manipulation of neurotransmission invariably affects spiking levels, and vice versa.
It is likely that no urinary biomarker will be able to perform all tasks of predicting AKI, for instance determining both severity and duration, as well as portending recovery.
