1. Choose a neural network framework
TensorFlow.js: Allows machine learning models to be defined, trained, and run in the browser.
ONNX.js: Supports running pre-built ONNX (Open Neural Network Exchange) models in the browser.
Brain.js: A JavaScript library that simplifies working with neural networks.
2. Prepare Your Neural Network Model
Train your model: You can train your model using frameworks like TensorFlow, PyTorch, or other machine learning frameworks.
Export the model: After training, export the model to a format compatible with the chosen frontend framework (eg TensorFlow.js format or ONNX format).
3. Set Up Your Frontend Project
Create Project: Create a new frontend project using a framework like meta, Vue or plain JavaScript / HTML.
Build required libraries:
npm @tensorflow/build tfjs
or
npm install onnxjs
depending on the library you plan to use.
4. Load and Run the Model in the Frontend
Load Model:
// For TensorFlow.js
* import as tf from @tensorflow/tfjs’;
async functionModel() {
const model = await tf.loadLayersModel( ‘path/to/model.json‘ );
return model;
}
For ONNX.js
// For ONNX.js
const onnx = required ( ‘onnxjs’ );
async functionModel() {
const session = new onnx.InferenceSession();
await session.loadModel(“path/to/model.onnx”);
return;
}
“`
How the model works:
// For TensorFlow.js
function async guess(input) {
const model = await loadModel();
const output = model.predict(tf.tensor(input));
return;
}
// For ONNX.js
function async guess(input) {
const session = await loadModel();
const tensor = onnx.new Tensor(input, ‘float32’);
const outputMap = await session.run([tensor]);
const outputTensor = outputMap.values (). Next(). price
returnTensor;
}
“`
5. Integrate with the Frontend
Create UI Components: Design login forms or other UI components to collect data from users.
Prediction Triggers: Add event listeners or handlers to send user data to neural network for prediction.
Result Display: Process the output of the neural network and display it in the UI.
Example: A simple React application with TensorFlow.js
1. Build the project
cd neural-network-front-end
npm @tensorflow/build tfjs
2. Create Components
App.js
* import as tf from @tensorflow/tfjs’;
const App = () => {
const [input, setInput] = useState(”);
const [output, setOutput] = useState(null);
const loadModel = async() => {
const model = await tf.loadLayersModel(‘/path/to/model.json‘);
return model;
};
const handlePredict = async() => {
const model = await loadModel();
const tensor = tf.tensor2d([parseFloat(input)], [1, 1]);
const prediction = model.predict(tensor);
setOutput(estimate.dataSync()[0]);
};
return (
<div>
<h1> Front Nervous System Integration</h1>
<input type = “text“ value = {input} onChange = {e => setInput(e.target.value)} />
<button click={handlePredict}>prediction</button>
{Log off! == null && <h2> Output: {output} </h2>}
</div>
);
};
export the main program;
