AI on Browser

Machine learning and data analysis package implemented in JavaScript and its online demo.

Features

• Most of the models are completed in a single file and implemented in a simple way.
• The machine learning part of the code does not use any external libraries, except for the loading part of the ONNX file.
• All processing in the demo is done in client-side JavaScript.

Links

• Online demo
• Package document
• Package release notes

Caution

• The code is not practical in terms of speed, memory usage, etc.
• There is no single compact file, and each model file exists only separately. However, it is possible to use them from the default import as shown in Example.

Examples

Ridge

import dam from '@ai-on-browser/data-analysis-models';

const x = dam.Matrix.randn(100, 3);
const y = x.sum(1);

const model = new dam.models.Ridge(0.1);
model.fit(x.toArray(), y.toArray());

const predict = model.predict(x.toArray());
const error = dam.evaluate.rmse(predict, y.toArray());
console.log(error);

NeuralNetwork

import dam from '@ai-on-browser/data-analysis-models';

const x = dam.Matrix.randn(100, 3);
const y = x.sum(1);

const layers = [
    { type: 'input' },
    { type: 'full', out_size: 5 },
    { type: 'tanh' },
    { type: 'full', out_size: 1 },
];
const model = dam.models.NeuralNetwork.fromObject(layers, 'mse', 'adam');
for (let i = 0; i < 100; i++) {
    model.fit(x.toArray(), y.toArray());
}

const predict = model.predict(x.toArray());
const error = dam.evaluate.rmse(predict, y.toArray());
console.log(error);

Q-learning

import dam from '@ai-on-browser/data-analysis-models';

const env = new dam.rl.CartPoleRLEnvironment();
const agent = new dam.models.QAgent(env, 6);

const n = 1.0e+4;
const totalRewards = []
for (let i = 0; i < n; i++) {
    let curState = env.reset();
    totalRewards[i] = 0;
    while (true) {
        const action = agent.get_action(curState, Math.max(0.01, 1 - i / 2000));
        const { state, reward, done } = env.step(action);
        agent.update(action, curState, state, reward);
        totalRewards[i] += reward;
        curState = state;
        if (done) {
            break;
        }
    }

    if (totalRewards.length >= 10 && totalRewards.slice(-10).reduce((s, v) => s + v, 0) / 10 > 150) {
        console.log(i, totalRewards[totalRewards.length - 1]);
        break;
    }
}
