Web ML: ML5.js
In the ever-evolving world of artificial intelligence (AI) and machine learning (ML), libraries and frameworks can make a significant difference in how accessible these technologies are to developers and hobbyists alike. One such library that stands out for its ease of use and creative potential is ML5.js. If you're curious about how to get started with ML5.js and explore its capabilities, this blog will guide you through the basics and provide a hands-on example to spark your creativity.
What is ML5.js?
ML5.js is a high-level JavaScript library built on top of TensorFlow.js. It aims to make machine learning accessible to artists, designers, educators, and developers by providing a user-friendly interface for creating, training, and deploying ML models directly in the browser. Its simplicity and ease of integration make it an excellent choice for projects that involve computer vision, natural language processing, and other ML tasks.
Why Choose ML5.js?
Getting Started with ML5.js
To start working with ML5.js, you need a basic setup of HTML and JavaScript. Here’s a step-by-step guide to create a simple project using ML5.js.
Prerequisites
Step 1: Set Up Your Project
Create a new directory for your project and add two files: index.html and script.js.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>ML5.js Example</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.4.0/p5.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/ml5/2.3.0/ml5.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<h1>ML5.js Example: Image Classification</h1>
<input type="file" id="upload" accept="image/*">
<div id="result"></div>
</body>
</html>
script.js
let classifier;
let img;
let resultDiv;
function setup() {
noCanvas();
resultDiv = select('#result');
classifier = ml5.imageClassifier('MobileNet', modelLoaded);
// Setup the file input
select('#upload').elt.addEventListener('change', handleFile);
}
function modelLoaded() {
console.log('Model Loaded!');
}
function handleFile(event) {
let file = event.target.files[0];
img = createImg(URL.createObjectURL(file), imageReady);
img.hide();
}
function imageReady() {
classifier.classify(img, gotResult);
}
function gotResult(error, results) {
if (error) {
console.error(error);
return;
}
let label = results[0].label;
let confidence = nf(results[0].confidence, 0, 2);
resultDiv.html(`Label: ${label}<br>Confidence: ${confidence}`);
}
Step 2: Explanation
Step 3: Run Your Project
Open index.html in your web browser. You should see a file upload input. Upload an image, and the ML5.js MobileNet model will classify the image and display the results.
