  1. BERT: BERT (Bidirectional Encoder Representations from Transformers) is a pre-trained language model developed by Google that achieved state-of-the-art results on various NLP tasks.
    2. 

  2. RoBERTa: RoBERTa (Robustly optimized BERT pretraining approach) is a variant of BERT that uses a different optimization algorithm and achieves better results on some NLP tasks.

After training the model, it's essential to evaluate its performance. Some popular metrics for evaluating language models include: Build A Large Language Model -from Scratch- Pdf -2021


Tokenization: Breaking raw text into smaller units (tokens) that the model can process. While there is no record of a book


    

  • Perplexity: a measure of how well the model predicts the next word in a sequence
    • 

  • BLEU score: a measure of how well the model generates text that is similar to human-written text
    •
