Anirudh Acharya commented on MXNET-376:
---------------------------------------
Currently hardmax is accomplished using existing mxnet operators. For example -
{code:java}
# Compute Hardmax with axis=1
x = np.random.rand(2,3,4)
xn = mx.nd.array(x)
xn_r = mx.nd.reshape(xn, shape=(2,12))
xn_e = mx.nd.eye(xn_r.shape[1], dtype=x.dtype)[mx.nd.argmax(xn_r, axis=1)]
hardmax_output = mx.nd.reshape(xn_e, shape=xn.shape)
print(hardmax_output)
{code}
But a direct hardmax implementation would be more convenient and useful for
users who would want to build their networks with mxnet.
