Tensor
A Tensor is a multi-dimensional mathematical array of numbers that serves as the fundamental data structure for representing inputs, weights, and activations in deep learning frameworks like TensorFlow and PyTorch.
Frequently Asked Questions
How does a tensor differ from a matrix or vector?▼
A vector is a 1D tensor, a matrix is a 2D tensor, and tensors can extend to three or more dimensions (e.g., 3D, 4D, 5D tensors).
Why are GPUs highly efficient at processing tensors?▼
GPUs contain thousands of small arithmetic cores designed to perform matrix and tensor mathematical operations (like dot products and additions) in parallel.
