In the second phase, the candidate on-shelf utility itemsets are further checked for their actual utility values by an additional database scan.
The experimental data comprise a series of 12 tests in pure torsion and an additional database of experimental information for 24 specimens compiled from works around the world.
This route is a bit clunkier — but it's also a bit simpler to implement and easier on Apples servers, as it doesn't require an additional database call for each and every user for each and every app.
This model generates candidates with no smaller overestimation values than a given threshold in the first phase and then identifies actual high utility patterns by computing their utility values through an additional database scan.
In contrast to some existing open-source tools that are limited to a distinct operating system, depend upon the installation of an additional database or require a specific input format, CheS-Mapper is platform independent, requires no installation, and accepts a wide range of chemical formats.
Lee told VICE he's not sure the impact increased record-keeping would have on crime deterrence, but given that cops often have issues tracing the origin of a gun, having an additional database could prove useful.
