Study Notes
Word Meaning and Context
- Language models (LLMs) can represent the same word with different vectors based on context.
- A "bank" can be a financial institution or land beside a river.
- "Magazine" can represent a physical publication or an organization.
Transformers: Attention and Feed Forward
- LLMs use a transformer architecture for text processing.
- The transformer includes an attention step and a feed-forward step.
- The attention step allows words to connect and share contextual information.
- The feed-forward step helps words process shared information and predict the next word.
- Attention heads are like a matchmaking service, retrieving information from earlier parts of a prompt.
- Feed-forward layers act like a database, storing information learned from training data.
Training Language Models
- LLMs learn without needing explicitly labeled data.
- They learn by predicting the next word in sequences of text.
- The training process adjusts weight parameters using backpropagation.
- Backpropagation analyzes the flow of information through the network to adjust weights for improved predictions.
The Power of Scale
- LLMs are trained on massive amounts of text data.
- The size of the model and training data heavily influence its accuracy and capabilities.
- OpenAI's GPT-3 was trained on 500 billion words, compared to an average human child learning 100 million words by age 10.
- OpenAI's experiments show that the accuracy of its language models scaled proportionally to the size of the model, training dataset, and computing power used.
