tensorflow :: operaciones :: SparseReduceMax
#include <sparse_ops.h> Calcula el máximo de elementos en las dimensiones de un SparseTensor.
Resumen
Esta operación toma un SparseTensor y es la contraparte dispersa de tf.reduce_max() . En particular, esta Op también devuelve un Tensor denso en lugar de uno escaso.
Reduce sp_input largo de las dimensiones dadas en reduction_axes . A menos que keep_dims sea verdadero, el rango del tensor se reduce en 1 por cada entrada en reduction_axes . Si keep_dims es verdadero, las dimensiones reducidas se retienen con la longitud 1.
Si reduction_axes no tiene entradas, todas las dimensiones se reducen y se devuelve un tensor con un solo elemento. Además, los ejes pueden ser negativos, que se interpretan de acuerdo con las reglas de indexación en Python.
Argumentos:
- alcance: un objeto de alcance
- input_indices: 2-D. Matriz
N x R con los índices de valores no vacíos en un SparseTensor, posiblemente no en orden canónico. - input_values: 1-D.
N valores no vacíos correspondientes a input_indices . - input_shape: 1-D. Forma de la entrada SparseTensor.
- ejes_de_reducción: 1-D. Longitud: vector
K que contiene los ejes de reducción.
Atributos opcionales (consulte Attrs ):
- keep_dims: si es verdadero, conserva las dimensiones reducidas con longitud 1.

In particular, this Op also returns a dense [Tensor](/versions/r2.2/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) instead of a sparse one.\n\nReduces `sp_input` along the dimensions given in `reduction_axes`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `reduction_axes`. If `keep_dims` is true, the reduced dimensions are retained with length 1.\n\nIf `reduction_axes` has no entries, all dimensions are reduced, and a tensor with a single element is returned. Additionally, the axes can be negative, which are interpreted according to the indexing rules in Python.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.2/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- input_indices: 2-D. `N x R` matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering.\n- input_values: 1-D. `N` non-empty values corresponding to `input_indices`.\n- input_shape: 1-D. Shape of the input SparseTensor.\n- reduction_axes: 1-D. Length-`K` vector containing the reduction axes.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.2/api_docs/cc/struct/tensorflow/ops/sparse-reduce-max/attrs#structtensorflow_1_1ops_1_1_sparse_reduce_max_1_1_attrs)):\n\n- keep_dims: If true, retain reduced dimensions with length 1.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.2/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): `R-K`-D.
