Neurons in Large Language Models: Uncovering the Secrets of Activation Patterns

Source: arxiv.org - PDF - 8,257 words - view

"Large language models (LLMs) have sparse activation patterns"


• Many neurons in the early part of the network are "dead"

• This sparsity is evident in LLMs, particularly in the OPT family of models

• Sparse activation patterns challenge traditional views of neural networks

"Positional neurons in FFN layers defy conventional understanding"


• These neurons do not align with the key-value memory view

• They can be used in unconventional ways within the network

• Their role in LLMs is still not fully understood

"Dedicated neurons and the challenge of semantic concepts"


• Larger LLMs have dedicated neurons for certain features

• However, the space of fine-grained semantic concepts exceeds available neurons

• This poses a limitation in effectively representing all possible concepts

"Token-detecting neurons enable comprehensive coverage"


• Token-detecting neurons exhibit ensemble-like behavior

• They cover different tokens in different layers, allowing for wide coverage

• This behavior is observed in larger LLMs and supports effective token detection

"Unveiling dead neurons and positional information"


• Dead neurons in LLMs play a role in encoding token position

• The top suppressed concepts trigger these neurons

• Vector updates for these neurons point towards next token candidates

"Positional neurons encode absolute position accurately"


• Positional neurons can accurately encode absolute position without positional encoding

• Some positional neurons exhibit extreme activation values (0 or 1) based solely on position

• Oscillatory patterns may emerge with longer training time

"Neurons as fundamental units of analysis"


• Neurons have been extensively studied in various neural network models

• Initial focus was on convolutional networks for images and text classifiers

• Similar findings of n-gram detectors have been observed in small convolutional text classifiers

"References for further exploration"


• This document provides a list of references for related papers and datasets

• Key papers include "Adaptively Scaling Laws for Neural Language Models" and "Impact of Positional Encoding on Length Generalization in Transformers"

• These references offer deeper insights into the field of neural language models

"Uncovering the Secrets of Neurons in LLMs"


• The activation patterns of neurons in LLMs are sparse, with many "dead" neurons

• Positional neurons challenge traditional views and encode valuable information

• Further research is needed to fully understand the behavior and potential of neurons in LLMs
