jsdoでtensorflow.js

Last updated at Posted at 2018-04-03

概要

jsdoでtensorflow.jsやってみた。

サンプルコード

const model1 = tf.sequential();
model1.add(tf.layers.dense({
    units: 1, 
    inputShape: [1]
}));
model1.compile({
    loss: 'meanSquaredError', 
    optimizer: 'sgd'
});
const xs = tf.tensor2d([1, 2, 3, 4], [4, 1]);
const ys = tf.tensor2d([1, 3, 5, 7], [4, 1]);
model1.fit(xs, ys).then(() => {
    model1.predict(tf.tensor2d([5], [1, 1])).print();
});

function predict(input) {
  return tf.tidy(() => {
    const x = tf.scalar(input);
    const ax2 = a.mul(x.square());
    const bx = b.mul(x);
    const y = ax2.add(bx).add(c);
    return y;
  });
}
const a = tf.scalar(2);
const b = tf.scalar(4);
const c = tf.scalar(8);
const result = predict(2);
result.print()
