Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Algoritmos de ML y para la extracción de características de LearningML

Readme

lml-algorithms

Librería de algoritmos de Machine Learning y extractores de características usada por LearningML.

Qué incluye

  • Algoritmos de clasificación:
    • LMLSequential (red neuronal feed-forward con TensorFlow.js)
    • KNN
    • NaiveBayes gaussiano
  • Extracción de características:
    • Numérica (numericalEncoder)
    • Texto tipo Bag of Words (bowEncoder)
    • Audio (audioEncoder)
    • Imagen con MobileNet (getMobilenetEncoder)
  • Utilidades para preparación de datos, validación y matriz de confusión.

Instalación

Este repositorio usa JavaScript + TensorFlow.js y está preparado para ejecutarse con bun o npm.

bun install

Alternativa:

npm install

API principal

Exportada desde src/index.js:

  • Encoders: getMobilenetEncoder, numericalEncoder, bowEncoder, audioEncoder
  • Audio helpers: collectExample, playRawAudio
  • Algoritmos: LMLSequential, KNN, NaiveBayes, LMLModelFactory
  • Utilidades: confusionMatrix, transformObjectToMapWithTensors, combineMapsOfTensors, extendArraysInObject

Tests

La estrategia de tests está definida en AGENTS.md y se implementa con Vitest.

Política de ejecución recomendada

  • npm test (vitest run) es la ejecución de referencia en CI.
  • bun test está soportado para desarrollo local rápido.
  • El test de contrato de mobilenet se marca como skip en el runner nativo de Bun porque su sistema de mocks no aísla módulos de tfjs-core igual que Vitest; ese contrato sí se valida en npm test.

Ejecutar todos los tests

bun test

Ejecutar solo unitarios

bun run test:unit

Ejecutar solo integración

bun run test:integration

Modo watch

bun run test:watch

Con npm

npm test
npm run test:unit
npm run test:integration

Estructura de tests

  • tests/unit: utilidades, encoders, factoría de modelos y tests de contrato con mocks para dependencias de navegador/modelos externos.
  • tests/integration: flujos completos de entrenamiento, clasificación y persistencia (localStorage) para los algoritmos.
  • tests/setup/vitest.setup.js: inicialización de backend de TensorFlow para tests.
