VECTOR KIT

Vector Kit seeks to make vector arithmetic simple for everyone. It may serve as a utility in a large ecosystem of scientific libraries or, more simply, as a toy to be played with to understand Vector math. This is a work in progress, and may not yet be ready for large data munging.

IMPORTING

import vectorkit

OR,

from vectorkit import Vector, isovector, randvec

OVERVIEW

Properties

components - a list of the components of a vector

dimensions - the dimension of the vector, or count of its components

min - the minimum component

max - the maximum component

sum - the sum of the components of a vector

memsize - the size of a vector in memory

Methods

add - Adds two vectors

append - Appends new components to a vector

concat - Merges two vectors into a single vector

corr - Returns the correlation of two vectors

cov - Returns the covariance between two vectors

describe - Returns a description of a vector, including its dimensions and memory size

distance - Returns the euclidean distance between two vectors

dotmul - Returns the dot product between two vectors

insert - Inserts a new component at a specified index

magnitude - Returns the magnitude of a vector

mean - Returns the mean of the components of a vector

minmax - Returns a variant of a vector which has been normalized using standard min-max feature scaling

minmaxmean - Returns a variant of a vector which has been normalized using standard mean and min-max feature scaling

mse - Returns the mean square error of two vectors

normalize - Returns a variant of a vector which has been normalized using the z-score or standard deviation

pad - Appends zeroes to vectors to a specified length, in-place

padded - Returns a new vector with zero appended to it to a specified length,

pop - Removes a component at a specified location

relu - Passes a vector through a Rectified Linear Unit function and returns a new vector

reverse - Reverses the direction of a vector in-place

reversed - Returns a variant of a vector with reversed direction

sdiv - Returns a new vector, which is the quotient from a scalar division of a vector

shuffle - Shuffles vector components in place

shuffled - Returns a new vector with shuffled version of a vector's components

sigmoid - Passes a vector through a logistic sigmoid function and returns a new vector

smul - Returns a new vector, which is the product from a scalar multiplication of a vector

softmax - Passes a vector through a softmax function and returns a new vector

std - Returns the standard deviation of the components of a vector

stdnorm - Returns a variant of a vector which has been normalized using the z-score or standard deviation

subtract - Returns a new vector, which is the result of the subtraction of one vector from another

subvec - Returns a new vector which is a slice from the original vector

tanh - Passes a vector through a TanH function and returns a new vector

to_list - Returns a list of the components of a vector

to_tuple - Returns a tuple of the components of a vector

unitvec - Returns a new vector which has been scaled to unit length

vector_eq - Returns the vector equation of a line between two vectors

Other

isovector - Returns a vector of a specified length containing the same component throughout

randvec - Generates a vector of specified length having random components
