We set up a new, flexible approach for the tensor reduction of one-loop Feynman integrals. The 5-point tensor integrals up to rank R = 5 are expressed by ...

Tensor sufficient dimension reduction Wenxuan Zhong,1∗ Xin Xing1 and Kenneth Suslick2 Tensor is a multiway array. With the rapid development of science and technology in the past decades, large amount of tensor observations are routinely collected, processed, and stored in many scientific researches and commercial activities nowadays.

Jul 22, 2019 · Tensor data are data with multiway array structure. They are often very high dimensional and are routinely encountered in many scientific fields. Dimension reduction is the technique of reducing the number of underlying variables for compressed data representation and for model parsimony.

In multilinear algebra, a tensor contraction is an operation on a tensor that arises from the natural pairing of a finite-dimensional vector space and its dual. In components, it is expressed as a sum of products of scalar components of the tensor(s) caused by applying the summation convention to a pair of dummy indices that are bound to each other in an expression. The contraction of a single mixed tensoroccurs when a pair of literal indices (one a subscript, the other a superscript) of th…

2 dager siden · This is the reduction operation for the elementwise tf.math.add 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.

Reducing tensors by axes To reduce a tensor with respect to a specific axis, we use the same methods, and we just pass a value for the dimension parameter. Let's see this in action. Suppose we have the following tensor:

A reduction operation on a tensor is an operation that reduces the number of elements contained within the tensor. So far in this series, we've learned that tensors are the data structures of deep learning.

In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Objects that tensors may map between include vectors and scalars, and even other tensors. There are many types of tensors, including scalars and vectors (which are the simplest tensors), dual vectors, multilinearmaps between vector spaces…
