Study Notes
Vocabulary Development
- Fluent speakers possess extensive knowledge, primarily reflected in vocabulary.
- Estimates for young adult American English speakers' vocabulary range from 30,000 to 100,000 words.
- Active vocabulary for young speakers averages around 2,000 words, acquired early through interaction.
- Children typically learn 7 to 10 new words daily to reach vocabulary levels by age 20.
- Vocabulary growth rates observed in studies align with these daily learning estimates.
- The main mechanism for vocabulary acquisition is through reading, with significant processing occurring during this activity.
Learning Mechanisms
- The distributional hypothesis suggests meaning can be learned from text based on word associations and co-occurrences.
- Early vocabulary engagement is established through conversation, with additional growth primarily stimulated by reading.
- Children may outpace the introduction of new words through efficient learning mechanisms during exposure to diverse texts.
Large Language Models (LLMs)
- LLMs are built from vast text data during pretraining, allowing them to learn complex language and world knowledge.
- They exhibit high performance on various natural language processing tasks, such as summarization and machine translation.
- The transformer architecture, introduced in earlier chapters, is essential for developing causal or autoregressive language models, predicting words sequentially from previous context.
- LLMs have transformed technology applications, including chatbots and question-answering systems, due to their ability to generate coherent text.
Implications of Pretraining
- Pretraining establishes foundational knowledge about language and context from extensive text exposure.
- Grounding knowledge through real-world interactions enhances model performance further, yet even text-based learning proves to be highly beneficial.
