In this case, it can cause the information gain of each of these attributes to be much higher than those without as many distinct values. To counter this problem, Ross Quinlan proposed to instead choose the attribute with highest information gain ratio from among the attributes whose information gain is average or higher. [ 5 ]
l-diversity, also written as ℓ-diversity, is a form of group based anonymization that is used to preserve privacy in data sets by reducing the granularity of a data representation. This reduction is a trade off that results in some loss of effectiveness of data management or mining algorithms in order to gain some privacy.
In mathematics and logic, the term "uniqueness" refers to the property of being the one and only object satisfying a certain condition. [1] This sort of quantification is known as uniqueness quantification or unique existential quantification, and is often denoted with the symbols "∃!"
The split information value is a positive number that describes the potential worth of splitting a branch from a node. This in turn is the intrinsic value that the random variable possesses and will be used to remove the bias in the information gain ratio calculation.
A home invasion in an upscale Philadelphia suburb turned fatal over the weekend after a suspect broke into a home in Lower Merion Township at 2:20 a.m. on Sunday, Dec. 8, the Montgomery County ...
Americans are obsessed with a white Christmas and all the trimmings – snow, icicles, sleigh rides, frost on windowpanes, cuddling up by the fire, mittens, the North Pole.
WASHINGTON (Reuters) -A group of 16 states led by California and environmental groups dropped a lawsuit filed in 2022 that sought to block the U.S. Postal Service's plan to buy mostly gas-powered ...
IEEE 754 NaNs are encoded with the exponent field filled with ones (like infinity values), and some non-zero number in the significand field (to make them distinct from infinity values); this allows the definition of multiple distinct NaN values, depending on which bits are set in the significand field, but also on the value of the leading sign ...
