# chainer.functions.batch_l2_norm_squared¶

chainer.functions.batch_l2_norm_squared(x)[source]

L2 norm (a.k.a. Euclidean norm) squared.

This function implements the square of L2 norm on a vector. No reduction along batch axis is done.

Parameters

x (Variable or N-dimensional array) – Input variable. The first dimension is assumed to be the minibatch dimension. If x has more than two dimensions all but the first dimension are flattened to one dimension.

Returns

Two dimensional output variable.

Return type

Variable
