Dask Bag [15] is an unordered collection of repeated objects, a hybrid between a set and a list. Dask Bag is used to parallelize computation of semi-structured or unstructured data, such as JSON records, text data, log files or user-defined Python objects using operations such as filter, fold, map and groupby.
In mathematics, a family, or indexed family, is informally a collection of objects, each associated with an index from some index set.For example, a family of real numbers, indexed by the set of integers, is a collection of real numbers, where a given function selects one real number for each integer (possibly the same) as indexing.
[1] [2] For instance, if the elements of a set A may be indexed or labeled by means of the elements of a set J, then J is an index set. The indexing consists of a surjective function from J onto A , and the indexed collection is typically called an indexed family , often written as { A j } j ∈ J .
In contrast to a cost-of-living index based on the true but unknown utility function, a superlative index number is an index number that can be calculated. [1] Thus, superlative index numbers are used to provide a fairly close approximation to the underlying cost-of-living index number in a wide range of circumstances. [1] Some indexes are not ...
The Tversky index, named after Amos Tversky, [1] is an asymmetric similarity measure on sets that compares a variant to a prototype. The Tversky index can be seen as a generalization of the Sørensen–Dice coefficient and the Jaccard index. For sets X and Y the Tversky index is a number between 0 and 1 given by
The Python Package Index, abbreviated as PyPI (/ ˌ p aɪ p i ˈ aɪ /) and also known as the Cheese Shop (a reference to the Monty Python's Flying Circus sketch "Cheese Shop"), [2]: 8 [3]: 742 is the official third-party software repository for Python. [4] It is analogous to the CPAN repository for Perl [5]: 36 and to the CRAN repository for R.
Bovespa Index 1994–2019. The index is a total return index composed by a theoretical portfolio as follows: [2] Selection criteria: Being amongst the eligible stocks that account for 85% in descending order by individual tradability ratio (IN); Traded in 95% of the trading sessions; 0.1% of the value traded on the cash equity market (round lots); and must not be a penny stock.
In 2013, the Indian government authorities, in co-operation with seva volunteers, monks and Indian companies, set up 11 sectors with 55 camp clusters, providing round-the-clock first aid, ambulance, pharmacy, sector cleaning, sanitation, food and water distribution (setting up 550 kilometres (340 mi) of pipelines operated by 42 pumps), cooking ...
