The Transformer Architecture: A Powerful and Resilient Neural Network

The transformer architecture, introduced in 2016, has become a dominant approach in AI. It is a general-purpose differentiable computer that is expressive, optimizable, and efficient. Its design allows for complex computation in the forward pass, enabling it to tackle a wide range of problems. Additionally, it can be trained using backpropagation and gradient descent, making it optimizable. The transformer is also designed to run efficiently on our hardware, leveraging parallelism. Its resilience and versatility make it a formidable architecture in the AI field.
