'-ment' word endings split mid-word

What this neuron does

This neuron fires on the middle pieces of longer words that end in 'ment', such as 'assessment', 'allotment' and 'abandonment'. It is quiet, or goes the other way, on the word 'half' in phrases like 'at half past'. Turning it up made the model produce odd words ending in 'ment', so the pattern shows up in the output too.

Push this neuron up or down while the model writes, and watch what changes. The outputs were generated ahead of time, so nothing runs in your browser.

Which neurons in earlier layers feed this one, and which later ones it feeds. Amber links excite, blue links suppress; longer bars are stronger.

Activation histogram

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.

Logit lens

The words this neuron nudges the model toward (amber) or away from (blue) when it fires. A hint, not a label: many neurons work through later layers instead.
