Web11 Apr 2024 · This paper addresses the following research question: ``can one compress a detailed 3D representation and use it directly for point cloud registration?''. Map compression of the scene can be achieved by the tensor train (TT) decomposition of the signed distance function (SDF) representation. It regulates the amount of data reduced by … Web31 Dec 2024 · Tensor-Tensor Products for Optimal Representation and Compression. In this era of big data, data analytics and machine learning, it is imperative to find ways to compress large data sets such that intrinsic features necessary for subsequent analysis are not lost. The traditional workhorse for data dimensionality reduction and feature …
WebIn machine learning, the word tensor informally refers to two different concepts that organize and represent data. Data may be organized in an M-way array that is informally referred to as a "data tensor". However, a tensor is a multilinear mapping over a set of domain vector spaces to a range vector space.

In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Tensors may map between different objects such as vectors, scalars, and even other tensors. There are many types of tensors, including scalars and vectors … See more Although seemingly different, the various approaches to defining tensors describe the same geometric concept using different language and at different levels of abstraction. As multidimensional … See more Assuming a basis of a real vector space, e.g., a coordinate frame in the ambient space, a tensor can be represented as an organized multidimensional array of numerical values … See more There are several operations on tensors that again produce a tensor. The linear nature of tensor implies that two tensors of the same type may be added together, and that tensors … See more Tensor products of vector spaces The vector spaces of a tensor product need not be the same, and sometimes the elements of such a … See more An elementary example of a mapping describable as a tensor is the dot product, which maps two vectors to a scalar. A more complex example is the Cauchy stress tensor T, which takes a directional unit vector v as input and maps it to the stress vector T , … See more There are several notational systems that are used to describe tensors and perform calculations involving them. Ricci calculus Ricci calculus is … See more Continuum mechanics Important examples are provided by continuum mechanics. The stresses inside a solid body or fluid are described by a tensor field.
