step method

@override void step()

Implementation

@override
void step() {
  for (int p = 0; p < parameters.length; p = p + 1) {
    Tensor<dynamic> param = parameters[p];
    List<double> gSum = _gSquaredSum[param.id]!;

    for (int i = 0; i < param.data.length; i = i + 1) {
      double gradient = param.grad[i];
      gSum[i] = gSum[i] + (gradient * gradient);
      param.data[i] = param.data[i] - (learningRate * gradient) / (sqrt(gSum[i]) + epsilon);
    }
  }
