Vectorizer

Vectorizer is a generic compatible module, which provides an efficient way to manage and manipulate sparse vectors. It supports operations such as applying values to vectors, calculating magnitudes, and computing cosine similarity.

Features

• Sparse Vector Representation: Efficiently store vectors with non-zero values only.
• Vector Operations: Includes methods for scaling, normalizing, and calculating cosine similarity.

Prerequisites

• Go 1.25.0 or above

Installation

go get -u github.com/softwarespot/vectorizer

Usage

A basic example of using Vectorizer.

package main

import (
	"fmt"

	"github.com/softwarespot/vectorizer"
)

func main() {
	// Create a vectorizer with the type "string"
   	vz := vectorizer.New[string](128)

	vec1 := vectorizer.NewVector[string]()
	vz.ApplyTo(vec1, "Event 1", 1)
	vz.ApplyTo(vec1, "Event 2", 2)
	vz.ApplyTo(vec1, "Event 3", 3)

	vec2 := vectorizer.NewVector[string]()
	vz.ApplyTo(vec2, "Event 2", 2)
	vz.ApplyTo(vec2, "Event 3", 3)

	fmt.Println(vec1.CosineSimilarity(vec2)) // outputs: 0.9636241116594316
}
