A brief introduction to LLMs
LLMs are a subset of artificial intelligence (AI) that are designed to process, understand, and generate human language. These models employ deep learning techniques and are trained on extensive text data to understand context, generate coherent text, and interact in human-like conversation. As mentioned in the previous chapter, LLMs resulted from the evolutionary journey of NLP in AI. This journey had some key milestones:
- Early stages of NLP: Initially, NLP models were rule-based, relying on manually crafted language rules. The advent of machine learning brought statistical models that learned from data. These models, however, were limited by their inability to understand language contextually.
- Breakthrough with Transformer models: The introduction of Transformer models in 2017 marked a significant evolution. As discussed in the previous chapter, using “attention mechanisms,” these models could focus on different parts of input...
