What is the meaning of Transformer?

A static device that transfers electric energy from one circuit to another by magnetic coupling; primarily used to transfer energy between different voltage levels, which allows the most appropriate voltages for power generation, transmission and distribution to be chosen separately.

A neural network architecture composed of layers of attention which takes sequences of tokens (representing text, images, audio, or other modalities) as input.
