| ``mx.symbol.log_softmax`` |
| ================================================== |
| |
| Description |
| ---------------------- |
| |
| Computes the log softmax of the input. |
| This is equivalent to computing softmax followed by log. |
| |
| |
| **Example**:: |
| |
| |
| >>> x = mx.nd.array([1, 2, .1]) |
| >>> mx.nd.log_softmax(x).asnumpy() |
| array([-1.41702998, -0.41702995, -2.31702995], dtype=float32) |
| |
| >>> x = mx.nd.array( [[1, 2, .1],[.1, 2, 1]] ) |
| >>> mx.nd.log_softmax(x, axis=0).asnumpy() |
| array([[-0.34115392, -0.69314718, -1.24115396], |
| [-1.24115396, -0.69314718, -0.34115392]], dtype=float32) |
| |
| Usage |
| ---------- |
| |
| .. code:: r |
| |
| mx.symbol.log_softmax(...) |
