tensorflow :: ops :: SparseReduceSumSparse
#include <sparse_ops.h> Calcula a soma dos elementos nas dimensões de um SparseTensor.
Resumo
Este Op leva um SparseTensor e é a contraparte esparsa de tf.reduce_sum() . Em contraste com SparseReduceSum , este Op retorna um SparseTensor.
Reduz sp_input ao longo das dimensões indicadas em reduction_axes . A menos que keep_dims seja true, a classificação do tensor é reduzida em 1 para cada entrada nos reduction_axes . Se keep_dims for true, as dimensões reduzidas são retidas com comprimento 1.
Se a reduction_axes não tiver entradas, todas as dimensões serão reduzidas e um tensor com um único elemento será retornado. Além disso, os eixos podem ser negativos, que são interpretados de acordo com as regras de indexação em Python.
Argumentos:
- escopo: um objeto Scope
- input_indices: 2-D. Matriz
N x R com os índices de valores não vazios em um SparseTensor, possivelmente não em ordenação canônica. - input_values: 1-D.
N valores não vazios correspondentes a input_indices . - forma_de_entrada: 1-D. Forma da entrada SparseTensor.
- redução_axes: 1-D. Vetor comprimento-
K contendo os eixos de redução.
Atributos opcionais (consulte Attrs ):
- keep_dims: se verdadeiro, retém as dimensões reduzidas com comprimento 1.

In contrast to [SparseReduceSum](/versions/r1.15/api_docs/cc/class/tensorflow/ops/sparse-reduce-sum#classtensorflow_1_1ops_1_1_sparse_reduce_sum), this Op returns a SparseTensor.\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/r1.15/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
