Transformer. An O-core transformer consisting of two coils of copper wire wrapped around a magnetic core. In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
Feb 24, 2012 · Key learnings: Transformer Definition: A transformer is a passive device that transfers electrical energy from one circuit to another using electromagnetic induction. Working Principle: The working principle of a transformer involves mutual induction between coils to transfer electrical energy.

A transformer is a deep learning architecture developed by Google and based on the multi-head attention mechanism, proposed in a 2017 paper "Attention Is All You Need". Text is converted to numerical representations called tokens, and each token is converted into a vector via looking up from a word embedding table.
Apr 20, 2023 · The transformer is a neural network component that can be used to learn useful representations of sequences or sets of data-points. The transformer has driven recent advances in natural language processing, computer vision, and spatio-temporal modelling.
