Interpretability nuance: >90% of neurons' strong activation bands carry clear meaning
builderjaydub · x · 2026-10-20
Responding to the viral "hitchhiker's guide" neuron (weakly fired by 1% of tokens, including unrelated numbers and generic text), the author argues the accurate claim is that the strong activation bands of >90% of neurons have clearly interpretable meaning. These concepts are often narrow — "birdwatcher's paradise," "Apollo 11's first step," "earworm songs" — and the "one job" framing only applies above p99.99 activation. The unexplained domain remains huge.
