NLP Tutorials — Part 20: Compressive Transformer

This particular architecture has a lower memory requirement than Vanilla Transformer and is similar to the Transformer-XL that models longer sequences efficiently. The below image depicts how the memory is compressed. We can also say that this is drawing some parallels to the human brain — We have a brilliant memory because of the power of compressing and storing information very intelligently. This sure seems interesting, doesn’t it?

NLP Tutorials — Part 19: Longformer: Long Document Transformer

In this article, we will be discussing Longformer, which overcomes one of the famous pitfalls of transformers — the inability to process long sequences because of its quadratic scaling with increase in the sequence length. The Longformer is a vanilla transformer with a change in the attention mechanism, which is a combination of local self-attention and a global attention. 

NLP Tutorials — Part 18: GPT-3

GPT-3 was a massive model of 175 billion parameters, way more than GPT-2, Google’s T5 and Microsoft’s Turing NLG model. The main objective of GPT-3 was to improve the few-shot and zero-shot tasks with a large training data and computational parameters. The GPT-3 did not fail in achieving this objective and blew away all other language models in a plethora of language modelling tasks. Let’s dive deep into the world of GPT-3

NLP Tutorials — Part 17: GPT-2

Hello and welcome back to the NLP Tutorials Blog series! In this article we will understand the model which is a successor to the GPT model i.e GPT-2. GPT-2 was trained with a very simple objective: generate text and build coherent essays and paragraphs. GPT-2 is a huge model — 1.5 billion parameters! GPT-2 has more than 10x times parameters and 10x times training data than GPT-1 making it a scaled up version of GPT. GPT-2 was so good that the authors did not release the original trained models due to concerns about misuse of the AI.
