请问有谁用过js-objectdetect(脸部/眼/手识别),

https://www.bootcdn.cn/js-objectdetect/

有谁知道 里的的
如：
objectdetect.frontalface.js

(function(module) {
"use strict";
var classifier = [24,24,-5.0425500869750977e+00,9,0,2,6,4,12,9,-1.,6,7,12,3,3.,-3.1511999666690826e-02,2.0875380039215088e+00,-2.2172100543975830e+00,0,2,6,4,12,7,-1.,10,4,4,7,3.,1.2396000325679779e-02,-1.8633940219879150e+00,1.3272049427032471e+00,0,2,3,9,18,9,-1.,3,12,18,3,3.,2.1927999332547188e-02,-1.5105249881744385e+00,1.0625729560852051e+00,..................................................]
module.frontalface = new Float32Array(classifier);
module.frontalface.tilted = false;
})(objectdetect);

这个 classifier 里的值是怎样来的 ? (classifier - 这个值应该就是特征码)
