elementWiseMultiply function

Tensor<Vector> elementWiseMultiply(Tensor<Vector> a, Tensor<Vector> b)

Implementation

Tensor<Vector> elementWiseMultiply(Tensor<Vector> a, Tensor<Vector> b) {
  int N = a.value.length;
  Vector outValue = [];
  for (int i = 0; i < N; i++) {
    outValue.add(a.value[i] * b.value[i]);
  }
  Tensor<Vector> out = Tensor<Vector>(outValue);
  out.creator = Node(
    [a, b],
    () {
      for (int i = 0; i < a.value.length; i++) {
        a.grad[i] += out.grad[i] * b.value[i];
        b.grad[i] += out.grad[i] * a.value[i];
      }
    },
    opName: 'multiply_vector', // <-- Changed from ambiguous 'multiply'
    cost: N,
  );
  return out;
