| ``mx.symbol.argmax`` |
| ======================================== |
| |
| Description |
| ---------------------- |
| |
| Returns indices of the maximum values along an axis. |
| |
| In the case of multiple occurrences of maximum values, the indices corresponding to the first occurrence |
| are returned. |
| |
| |
| **Example**:: |
| |
| |
| x = [[ 0., 1., 2.], |
| [ 3., 4., 5.]] |
| |
| // argmax along axis 0 |
| argmax(x, axis=0) = [ 1., 1., 1.] |
| |
| // argmax along axis 1 |
| argmax(x, axis=1) = [ 2., 2.] |
| |
| // argmax along axis 1 keeping same dims as an input array |
| argmax(x, axis=1, keepdims=True) = [[ 2.], |
| [ 2.]] |
| |

| Arguments |
| ------------------ |
| |
| +----------------------------------------+------------------------------------------------------------+ |
| | Argument | Description | |
| +========================================+============================================================+ |
| | ``data`` | NDArray-or-Symbol. | |
| | | | |
| | | The input | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``axis`` | int or None, optional, default='None'. | |
| | | | |
| | | The axis along which to perform the reduction. Negative | |
| | | values means indexing from right to left. ``Requires axis | |
| | | to be set as int, because global reduction is not | |
| | | supported | |
| | | yet.`` | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``keepdims`` | boolean, optional, default=0. | |
| | | | |
| | | If this is set to `True`, the reduced axis is left in the | |
| | | result as dimension with size | |
| | | one. | |
| +----------------------------------------+------------------------------------------------------------+ |
| | ``name`` | string, optional. | |
| | | | |
| | | Name of the resulting symbol. | |
| +----------------------------------------+------------------------------------------------------------+ |
| |
| Value |
| ---------- |
| |
| ``out`` The result mx.symbol |
