In the IEEE 754 binary interchange formats, NaNs are encoded with the exponent field filled with ones (like infinity values), and some non-zero number in the trailing 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 trailing ...
By default, a Pandas index is a series of integers ascending from 0, similar to the indices of Python arrays. However, indices can use any NumPy data type, including floating point, timestamps, or strings. [4]: 112 Pandas' syntax for mapping index values to relevant data is the same syntax Python uses to map dictionary keys to values.
They developed a set of 8,869 semantic relations and 10,675 syntactic relations which they use as a benchmark to test the accuracy of a model. When assessing the quality of a vector model, a user may draw on this accuracy test which is implemented in word2vec, [ 28 ] or develop their own test set which is meaningful to the corpora which make up ...
Property list files use the filename extension.plist, and thus are often referred to as p-list files. Property list files are often used to store a user's settings. They are also used to store information about bundles and applications , a task served by the resource fork in the old Mac OS.

The function NAND(a 1, a 2, ..., a n) is logically equivalent to NOT(a 1 AND a 2 AND ... AND a n ). One way of expressing A NAND B is A ∧ B ¯ {\displaystyle {\overline {A\land B}}} , where the symbol ∧ {\displaystyle {\land }} signifies AND and the bar signifies the negation of the expression under it: in essence, simply ¬ ( A ∧ B ...
This list of metro systems includes electrified rapid transit train systems worldwide. In some parts of the world, metro systems are referred to as subways , undergrounds , tubes , mass rapid transit ( MRT ), metrô or U-Bahn .
[2] Because it is space-filling, its Hausdorff dimension is 2 (precisely, its image is the unit square, whose dimension is 2 in any definition of dimension; its graph is a compact set homeomorphic to the closed unit interval, with Hausdorff dimension 1). The Hilbert curve is constructed as a limit of piecewise linear curves.
