Beyond the surface: Understanding How Decoders work in Transformers

In the ongoing series to explain Transformer Architecture better, this document is focused on Decoder. The Transformer decoder is a neural network component designed to generate output sequences based on encoded input representations. It employs self-attention mechanisms to understand the context of the input and the generated output, while using cross-attention to align with the original input sequence. The decoder generates output tokens one at a time, conditioned on both the encoded input and previously generated tokens.

This piece is crafted to enhance your understanding, whether you’re a seasoned data scientist or an inquisitive consultant stepping into the world of AI.
