Building a Decoder-Only Transformer Model Like Llama-2 and Llama-3

The large language models today are a simplified form of the transformer model. They are called decoder-only models because their role is similar to the decoder part of the transformer, which generates an output sequence given a partial sequence as input. Architecturally, they are closer to the encoder part of the transformer model. In this […]

Building a Transformer Model for Language Translation

The Transformer architecture, introduced in 2017, revolutionized sequence-to-sequence tasks like language translation by eliminating the need for recurrent neural networks. Instead, it relies on self-attention mechanisms to process input sequences. In this post, you’ll learn how to build a Transformer model from scratch. In particular, you will understand: How self-attention processes input sequences How transformer […]

Building a Seq2Seq Model with Attention for Language Translation

The attention mechanism, introduced by Bahdanau et al. in 2014, significantly improved sequence-to-sequence (seq2seq) models. In this post, you’ll learn how to build and train a seq2seq model with attention for language translation, focusing on: Why attention mechanisms are essential How to implement attention in a seq2seq model Let’s get started. Overview This post is […]
