Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words.
Zipf's law (/ z ɪ f /; German pronunciation:) is an empirical law stating that when a list of measured values is sorted in decreasing order, the value of the n-th entry is often approximately inversely proportional to n. The best known instance of Zipf's law applies to the frequency table of words in a text or corpus of natural language:
Their exact values are not known, but upper and lower bounds on their values have been proven, [15] and it is known that they grow inversely proportionally to the square root of the alphabet size. [16] Simplified mathematical models of the longest common subsequence problem have been shown to be controlled by the Tracy–Widom distribution. [17]
In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
The terms data dictionary and data repository indicate a more general software utility than a catalogue. A catalogue is closely coupled with the DBMS software. It provides the information stored in it to the user and the DBA, but it is mainly accessed by the various software modules of the DBMS itself, such as DDL and DML compilers, the query optimiser, the transaction processor, report ...
A property of this multiplier is that it uniformly distributes over the table space, blocks of consecutive keys with respect to any block of bits in the key. Consecutive keys within the high bits or low bits of the key (or some other field) are relatively common. The multipliers for various word lengths are: 16: a = 9E37 16 = 40 503 10
Any sequence of + integer, real, or complex values can be used as initial conditions for a constant-recursive sequence of order +. If the initial conditions lie on a polynomial of degree d − 1 {\displaystyle d-1} or less, then the constant-recursive sequence also obeys a lower order equation.
Standard Arabic forbids initial consonant clusters and more than two consecutive consonants in other positions, as do most other Semitic languages, although Modern Israeli Hebrew permits initial two-consonant clusters (e.g. pkak "cap"; dlaat "pumpkin"), and Moroccan Arabic, under Berber influence, allows strings of several consonants.
