Neuron–astrocyte networks might perform the core computations performed by AI transformer blocks
Fascinating ideas from Kozachkov et al. Their text contains primers on Astrocyte biology and the transformers found in AI Generative Pre-trained Transformers such as ChatGPT.
Significance
Transformers have become the default choice of neural architecture for many machine learning applications. Their success across multiple domains such as language, vision, and speech raises the question: How can one build Transformers using biological computational units? At the same time, in the glial community, there is gradually accumulating evidence that astrocytes, formerly believed to be passive house-keeping cells in the brain, in fact play an important role in the brain’s information ...
