LabelEncoder
Encoder of categorical values to integers. For k different values, encoding yields integer numbers from 0 to k-1 (inclusive).
Example:
// List of raw input values
var y = ['Car', 'Bike', 'Bike', 'Car', 'Duck', 'Bike'];
// Create encoder
var encoder = new LabelEncoder();
// Encode input values, encoding the values to integers
var yEncoded = encoder.encode(y);
console.log(yEncoded); // [0, 1, 1, 0, 2, 0]
// Decode the encoded values, and see that they match the original input values
console.log(encoder.decode(yEncoded)); // ['Car', 'Bike', 'Bike', 'Car', 'Duck', 'Bike']Constructor Summary
