Tensor

A tensor is a concept used in a variety of disciplines. Within the context of machine learning, I think of it as a potentially N-dimensional array:

• A Scalar is a 0-dimensional tensor
• A Vector is a 1-dimensional tensor
• A Matrix is a 2-dimensional tensor

Within this context it’s also a specific type within tools/libraries like pytorch and tensorflow.
