Obtaining the full contents of Wikipedia for reuse presents challenges, since direct cloning via a web crawler is discouraged. [W 112] Wikipedia publishes "dumps" of its contents, but these are text-only; as of 2023, there is no dump available of Wikipedia's images. [W 113] Wikimedia Enterprise is a for-profit solution to this. [249]
The simplest AI applications can be divided into two types: classifiers (e.g., "if shiny then diamond"), on one hand, and controllers (e.g., "if diamond then pick up"), on the other hand. Classifiers [98] are functions that use pattern matching to determine the closest match. They can be fine-tuned based on chosen examples using supervised ...
The infection fatality ratio (IFR) is the cumulative number of deaths attributed to the disease divided by the cumulative number of infected individuals (including asymptomatic and undiagnosed infections and excluding vaccinated infected individuals).
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction.
The term "genome" usually refers to the DNA (or sometimes RNA) molecules that carry the genetic information in an organism, but sometimes it is uncertain which molecules to include; for example, bacteria usually have one or two large DNA molecules (chromosomes) that contain all of the essential genetic material but they also contain smaller ...
"contents", an object table with the Stage as the root. [68] All objects in the program are stored here as references. [69] Scratch 2.0 uses the *.sb2 file format. These are zip files containing a .json file as well as the contents of the Scratch project including sounds (stored as .wav) and images (stored as .png). [70]
For example, the Gini coefficient for wealth inequality increased from 0.80 in 1983 to 0.84 in 1989. In the same year, 1989, the Gini coefficient for income was only 0.52. [ 56 ] The Gini coefficient is an economic tool on a scale from 0 to 1 that measures the level of inequality. 1 signifies perfect inequality and 0 represents perfect equality.
