tf.compat.v1.reduce_min

View source on GitHub

Computes the tf.math.minimum of elements across dimensions of a tensor. (deprecated arguments)

tf.compat.v1.reduce_min(
    input_tensor,
    axis=None,
    keepdims=None,
    name=None,
    reduction_indices=None,
    keep_dims=None
)

This is the reduction operation for the elementwise tf.math.minimum op.

Reduces input_tensor along the dimensions given in axis. Unless keepdims is true, the rank of the tensor is reduced by 1 for each of the entries in axis, which must be unique. If keepdims is true, the reduced dimensions are retained with length 1.

If axis is None, all dimensions are reduced, and a tensor with a single element is returned.

>>> x = tf.constant([5, 1, 2, 4])
>>> tf.reduce_min(x)
<tf.Tensor: shape=(), dtype=int32, numpy=1>
>>> x = tf.constant([-5, -1, -2, -4])
>>> tf.reduce_min(x)
<tf.Tensor: shape=(), dtype=int32, numpy=-5>
>>> x = tf.constant([4, float('nan')])
>>> tf.reduce_min(x)
<tf.Tensor: shape=(), dtype=float32, numpy=nan>
>>> x = tf.constant([float('nan'), float('nan')])
>>> tf.reduce_min(x)
<tf.Tensor: shape=(), dtype=float32, numpy=nan>
>>> x = tf.constant([float('-inf'), float('inf')])
>>> tf.reduce_min(x)
<tf.Tensor: shape=(), dtype=float32, numpy=-inf>
