torch_kthvalue: Kthvalue

In torch: Tensors and Neural Networks with 'GPU' Acceleration

Kthvalue

Description

Kthvalue

Usage

torch_kthvalue(self, k, dim = -1L, keepdim = FALSE)

Arguments

self	(Tensor) the input tensor.
k	(int) k for the k-th smallest element
dim	(int, optional) the dimension to find the kth value along
keepdim	(bool) whether the output tensor has dim retained or not.

kthvalue(input, k, dim=NULL, keepdim=False, out=NULL) -> (Tensor, LongTensor)

Returns a namedtuple ⁠(values, indices)⁠ where values is the k th smallest element of each row of the input tensor in the given dimension dim. And indices is the index location of each element found.

If dim is not given, the last dimension of the input is chosen.

If keepdim is TRUE, both the values and indices tensors are the same size as input, except in the dimension dim where they are of size 1. Otherwise, dim is squeezed (see torch_squeeze), resulting in both the values and indices tensors having 1 fewer dimension than the input tensor.

Examples

if (torch_is_installed()) {

x <- torch_arange(1, 6)
x
torch_kthvalue(x, 4)
x <- torch_arange(1,6)$resize_(c(2,3))
x
torch_kthvalue(x, 2, 1, TRUE)
}
