What is a tensor in machine learning? If you're new to machine learning, you've almost certainly seen the word "tensor." Tensors are common data structures in machine learning and deep learning (Google's open-source software library for machine learning is even called TensorFlow). But what is a tensor, exactly? In simple terms, a tensor is a dimensional data structure.
TensorFlow is a free and open-source software library for dataflow and differentiable programming across a range of tasks. It is a symbolic math library, and is also used for machine learning applications such as neural networks.
Why do we use tensors in machine learning?
Why sudden fascination for tensors in machine learning and deep learning? Tensors use matrix to represent. It makes it so much easy to represent information in an array. The pixel data can of the images can be so easily represented in an array.

Tensors are simply mathematical objects that can be used to describe physical properties, just like scalars and vectors. In fact tensors are merely a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor.
What is tensor AI?
A Tensor is a mathematical object similar to, but more general than, a vector and often represented by an array of components that describe functions relevant to coordinates of a space. Put simply, a Tensor is an array of numbers that transform according to certain rules under a change of coordinates.
What is tensor with example?
A tensor field has a tensor corresponding to each point space. An example is the stress on a material, such as a construction beam in a bridge. Other examples of tensors include the strain tensor, the conductivity tensor, and the inertia tensor.

Tensors and transformations are inseparable. To put it succinctly, tensors are geometrical objects over vector spaces, whose coordinates obey certain laws of transformation under change of basis. Vectors are simple and well-known examples of tensors, but there is much more to tensor theory than vectors.
