Understanding Memorization Mechanisms in Language Models


Khái niệm cốt lõi
Pre-training transforms forgetful language models into retentive ones, influenced by knowledge relevance and diversification.
Tóm tắt

Memory is crucial for cognitive functions, with pre-trained language models showing remarkable memorizing abilities. Vanilla models suffer from catastrophic forgetting, while pre-training enhances memory retention. Knowledge relevance and diversification significantly impact memory formation.

Retentive or Forgetful? Diving into the Knowledge Memorizing Mechanism  of Language Models

What other factors could potentially affect the memorization abilities of language models?

In addition to knowledge relevance and diversification, several other factors can influence the memorization abilities of language models. One crucial factor is the architecture and size of the model. Larger models with more parameters tend to have a higher capacity for memorization due to their increased complexity. The quality and quantity of training data also play a significant role in shaping a language model's ability to retain information. Additionally, the learning rate, optimization algorithms, and fine-tuning strategies can impact how well a model retains learned knowledge over time.

How do the memorization mechanisms of language models compare to human brain memorization?

The memorization mechanisms of language models exhibit similarities and differences compared to human brain memorization. Language models rely on neural networks that store information in weights and connections between neurons, akin to synapses in the brain. However, while language models excel at rote memorization tasks through repetitive learning cycles, they lack some aspects of human memory such as emotional context, sensory experiences, and episodic memory formation. Human brains utilize complex cognitive processes involving multiple regions like hippocampus for long-term memory consolidation which are not fully replicated in current AI systems.

Are there any synchronized transitions during pre-training that contribute to improved memory retention?

During pre-training stages of large-scale language models like BERT or GPT-2, there are synchronized transitions that significantly enhance memory retention capabilities. As these models undergo extensive exposure to diverse linguistic patterns during pre-training on vast corpora like Wikipedia or Bookcorpus datasets over numerous epochs or steps (e.g., 1 million steps), they gradually develop robust internal representations leading from forgetful behavior towards retentive characteristics by forming intricate connections among various pieces of information stored within their parameters.
