About this episode
This episode introduces Natural Language Autoencoders, an unsupervised method for interpreting large language models developed by researchers at Anthropic.
Introducing Natural Language Autoencoders (NLAs), an unsupervised method developed by researchers at Anthropic to translate the complex internal activations of large language models into human-readable text. By utilizing an activation verbalizer to describe model states and an activation reconstructor to map those descriptions back to vectors, NLAs provide a legible interface for AI interpretability and auditing. The researchers demonstrate that these tools can surface unverbalized reaso...
