In modern computer science, "tensors" refer to multi-dimensional data arrays. Modern deep learning libraries (such as TensorFlow or PyTorch) rely on tensor operations to process image data (3D tensors: width color channels) or video data (4D tensors: frames color channels) through neural networks. 4.
