meridian.backend.reduce_max

Computes tf.math.maximum of elements across dimensions of a tensor.

This is the reduction operation for the elementwise tf.math.maximum 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_max(x) x = tf.constant([-5, -1, -2, -4]) tf.reduce_max(x) x = tf.constant([4, float('nan')]) tf.reduce_max(x) x = tf.constant([float('nan'), float('nan')]) tf.reduce_max(x) x = tf.constant([float('-inf'), float('inf')]) tf.reduce_max(x) ```

See the numpy docs for np.amax and np.nanmax behavior.

input_tensor
The tensor to reduce. Should have real numeric type.
axis
The dimensions to reduce. If None (the default), reduces all dimensions. Must be in the range [-rank(input_tensor), rank(input_tensor)) .
keepdims
If true, retains reduced dimensions with length 1.
name
A name for the operation (optional).

The reduced tensor.
