mx.nd.argmin

Description

Returns indices of the minimum values along an axis.

In the case of multiple occurrences of minimum values, the indices corresponding to the first occurrence are returned.

Example:

x = [[ 0.,  1.,  2.],
[ 3.,  4.,  5.]]

// argmin along axis 0
argmin(x, axis=0) = [ 0.,  0.,  0.]

// argmin along axis 1
argmin(x, axis=1) = [ 0.,  0.]

// argmin along axis 1 keeping same dims as an input array
argmin(x, axis=1, keepdims=True) = [[ 0.],
[ 0.]]

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.
