Introduction to Large Language Models (LLMs): An Overview of BERT, GPT, and Other Popular Models

John Snow Labs

In this section, we will provide an overview of two widely recognized LLMs, BERT and GPT, and introduce other notable models like T5, Pythia, Dolly, Bloom, Falcon, StarCoder, Orca, LLAMA, and Vicuna. BERT excels in understanding context and generating contextually relevant representations for a given text.

3 LLM Architectures

Mlearning.ai

1️⃣ Autoencoders  — In auto-encoders, the decoder part of the transformer is discarded after pre-training and only the encoder is used to generated the output. The widely popular BERT and RoBERTa models were based on this architecture and performed well on sentiment analysis and text classification .

What are the Different Types of Transformers in AI

Mlearning.ai

In this article, we will delve into the three broad categories of transformer models based on their training methodologies: GPT-like (auto-regressive), BERT-like (auto-encoding), and BART/T5-like (sequence-to-sequence). Auto Regression is common in more than just Transformers.

Paper Summary #5 - XLNet: Generalized Autoregressive Pretraining for Language Understanding

Shreyansh Singh

The paper proposes XLNet, a generalized autoregressive pretraining method that enables learning bidirectional contexts over all permutations of the factorization order and overcomes the limitations of BERT due to the autoregressive formulation of XLNet. So, the training objective in the case of BERT becomes - Here m t is 1 when x t is masked.
