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.
Pandas (styled as pandas) is a software library written for the Python programming language for data manipulation and analysis. In particular, it offers data structures and operations for manipulating numerical tables and time series .
Python is a high-level, general-purpose programming language that is popular in artificial intelligence. [1] It has a simple, flexible and easily readable syntax. [2] Its popularity results in a vast ecosystem of libraries, including for deep learning, such as PyTorch, TensorFlow, Keras, Google JAX.
Python uses the + operator for string concatenation. Python uses the * operator for duplicating a string a specified number of times. The @ infix operator is intended to be used by libraries such as NumPy for matrix multiplication. [99] [100] The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to ...
var list := {0, 1} a, b := list The list will be unpacked so that 0 is assigned to a and 1 to b. Furthermore, a, b := b, a swaps the values of a and b. In languages without parallel assignment, this would have to be written to use a temporary variable var t := a a := b b := t since a := b; b := a leaves both a and b with the original value of b.
Object-oriented languages such as Java, Smalltalk or C#. Multi-paradigm languages such as Ada, C++, Common Lisp, Fortran, JavaScript, Object Pascal, Perl, Python, R. Most languages using less common paradigms: Functional languages such as Lisp and Haskell. Logic programming languages such as Prolog. General-purpose macro processor such as m4.
A basic example is in the argv argument to the main function in C (and C++), which is given in the prototype as char **argv—this is because the variable argv itself is a pointer to an array of strings (an array of arrays), so *argv is a pointer to the 0th string (by convention the name of the program), and **argv is the 0th character of the ...
Modern microprocessors will allow for much faster processing if 8-bit character strings are not hashed by processing one character at a time, but by interpreting the string as an array of 32-bit or 64-bit integers and hashing/accumulating these "wide word" integer values by means of arithmetic operations (e.g. multiplication by constant and bit ...
