the last zero in large numbers

What this neuron does

This neuron reacts to a zero that finishes a big number, such as the last 0 in 4,000 or 8000. It is a number-shape detector rather than a topic detector. Turning it up gave text with no clear link to numbers.

Fires most on

The text windows where this neuron's activation was highest. Amber marks positive activation; the outlined token is the peak. Hover a token for its strength.

1. #1 peak

   number must be lower than the safe working load of the wheel you intend to use.⏎For example, a 4,000-lb cart with 4 wheels required to carry a 6,00

2. #2 peak

   tars and waxes that stifle the process.⏎However, it turns out that these tars and waxes are no match for an 8000K (7,727°C) plasma arc which, through a combination

3. #3 peak

   , Laundry, hostel and canteen effluent waste. The above waste is treated through Pond setup in the institute with a capacity of 24000 KLD (Kilo Liters per Day). The entire treated water is used

4. #4 peak

   5000 copies and never went out of print.⏎This PDF is a full-text searchable reproduction

5. #5 peak

   are 610 mg of Sodium in this food.⏎Vitamins - This food has both Vitamin A and Vitamin C. One serving contains 500 International Units of Vitamin A and 1.2 mg of Vitamin C.<|endoftext|>

6. #6 peak

   sugar and fatty snacks.⏎People’s energy needs vary depending on age and activity levels but usually men require more energy than women. Men need about 2500 kcals and women about 2000 kcals per day.⏎Break

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.

1. #1 peak

   the growth of two human embryonic stem cell lines that lack PIG-A, and therefore do not contain any proteins known as glycosylphosphatidylinositol (GPI) anchor proteins on the cell’s surface. GPI anchor

2. #2 peak

   We found that, across the western Palaearctic, urban blackbird populations contain less genetic diversity than rural ones, urban populations

3. #3 peak

   ⏎Semiarid and desert climates occur in regions with little precipitation. Desert climates are drier than semiarid climates. Semiarid climates, also called steppe climates, usually border

4. #4 peak

   whose electrochemistry makes carbon capture appear nearly effortless. Their invention is a kind of battery: conductive electrodes coated with a compound called polyanthraquinone, which has a natural chemical attraction<|endoftext|>From: Michael Bar

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.
