'by' before a percentage or amount change

What this neuron does

This neuron fires on the word 'by' when it introduces how much something rose, fell or changed, such as 'fallen by 79 percent' or 'cut by a quarter'. Turning it down made the model repeat 'from', which is the opposite word for change, and turning it up made the model produce percentage word problems.

   developing breast cancer and with that understanding were able to offer their conclusion.⏎"Our results suggest that losing just 5 percent or more of one's weight could cut by a quarter to a half the risk for the most common, estrogen-sensitive breast cancers,"

Steering

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.

Most negative on

Where the activation went furthest below zero. Blue marks negative activation. Many neurons mean something different in each direction.

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.
