Tensor

tensor

[′ten·sər]

(mathematics)

An object relative to a locally euclidean space which possesses a specified system of components for every coordinate system and which changes under a transformation of coordinates.

A multilinear function on the cartesian product of several copies of a vector space and the dual of the vector space to the field of scalars on the vector space.

Tensor chip

An SoC (system-on-chip) from Google that made its first appearance in a smartphone on the Pixel 6 and 6 Pro in 2021. The Tensor chip has an 8-core CPU and 20-core GPU, an advanced image processor for photos and a machine learning processor for AI, known as the Tensor Processing Unit. There is also a context hub for very-low power functions. The Tensor SoC is built on a 5 nm process technology. See Pixel phone and TensorFlow.

TensorFLow

An open source framework for mathematical processing from Google. TensorFlow is deployed on all popular platforms to develop mathematical layers in neural networks for machine learning. The TensorFlow software library runs on CPUs, GPUs and specialized Tensor Processing Unit (TPU) chips. See deep learning, machine learning and Tensor chip.

The Tensor Layer
A "tensor" is a multidimensional array that can hold a variety of data types. The number of dimensions is the "tensor shape."

Tensor

 

a term in mathematics that came into use in the mid-19th century and has since been employed in two distinct senses. The term is most commonly used in the modern tensor calculus, where it refers to a special type of quantity that transforms according to a special law. In mechanics, particularly elasticity theory, the term is used as a synonym for a linear operator Φ that transforms a vector Φ into the vector Φx and is symmetric in the sense that the scalar product yΦx remains unchanged if the vectors x and y are interchanged. The term originally referred to the small tensile (hence “tensor”) and compressional strains arising in elastic deformation. It was subsequently carried over into other fields of mechanics. Thus, we speak of a deformation tensor, stress tensor, inertia tensor, and so on.
