Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
In multithreaded programs, this can cause race conditions that result in the creation of multiple instances. The following Java 5+ example [ 6 ] is a thread-safe implementation, using lazy initialization with double-checked locking .
It disregards word order (and thus most of syntax or grammar) but captures multiplicity. The bag-of-words model is commonly used in methods of document classification where, for example, the (frequency of) occurrence of each word is used as a feature for training a classifier. [1] It has also been used for computer vision. [2]
The word embedding approach is able to capture multiple different degrees of similarity between words. Mikolov et al. (2013) [ 26 ] found that semantic and syntactic patterns can be reproduced using vector arithmetic.

[…] Paragraph, which means a segment can only be located at an address that is a multiple of 16, starting from address 0.

For example, the algorithms LDIS, [6] CDIS [7] and XLDIS [8] select the densest instances in a given arbitrary neighborhood. The selected instances can include both, border and internal instances. The LDIS and CDIS algorithms are very simple and select subsets that are very representative of the original dataset.
In computer programming, a block or code block or block of code is a lexical structure of source code which is grouped together. Blocks consist of one or more declarations and statements . A programming language that permits the creation of blocks, including blocks nested within other blocks, is called a block-structured programming language .
