Eigen::Tensor is a C++ library for tensor operations, developed by the Eigen team. It provides a high-level API for performing tensor operations, such as tensor addition, multiplication, and convolution. The library is designed to be fast and efficient, and provides support for both CPU and GPU acceleration. Eigen::Tensor is particularly useful for machine learning applications, where tensors are commonly used to represent data.
