Module to iterate over a numerically function to Gradient Descent direction
npm install gradient-descentModule to iterate over a numerically function to Gradient Descent direction
#### GD(initialPoint,asyncNumericalFunc,stepSize,deltaSize,numSteps,presicion)->Promise(bestParams)
Iterate NUM_STEPS and stop when the norm of gradient is less that PRESICION,
every step is of size STEP_SIZE and the numerical derivate is aproximated by:
derivate = [f(x + DELTA_SIZE) - f(x)]/DELTA_SIZE
``js``
const optimze = require('gradient-descent')
const func = async (x, y, z) => x x + y y + z * z;
const init = [3, 4, 5]; // dimension is obtained from initial point
const res = await optimize(init, func);
assert(await func(...res) < await func(...init));
