New Nine application domains — see what we are tracking

Understanding the systems we are building.

We study how machine learning systems represent the world, where those representations break down, and what it takes to make model behaviour predictable enough to rely on.

Research areas
4

Interpretability, measurement, robustness, efficiency

Application domains
9

From robotics and genomics to formal mathematics

Method

Read the representation,
not the output

A model’s answer tells you what it did. Its internal state tells you why. We decompose activations into a sparse basis and ask whether the features we recover are the ones the model is actually using — or the ones our method happens to be good at finding.

How we test that

A projection of layer-14 activations showing four labelled clusters and a handful of unresolved points.

How we work

Fewer results, held to a higher bar

01

Publish the negative results

Most of what a lab learns is which approaches do not work. We write those up too. A research programme that only reports its successes is not reporting its findings.

02

Release the artefacts

Code, evaluation suites and model probes ship with the paper under a permissive licence. A result that cannot be reproduced by a reader is a claim, not a finding.

03

Say what we do not know

Every write-up carries an explicit limitations section stating the conditions under which we expect the result to fail. We would rather be narrow and correct than broad and unfalsifiable.

Open tooling

Every figure here is
a reproducible artefact

We release the harness that produced a result alongside the result itself. If a reader cannot regenerate the plot on their own machine, we have published a claim rather than a finding — and we would rather not do that.

What we commit to

A causal attention heatmap for head 7, with three strongly attended key positions.

Bring us a
measurement problem

If you work in one of these domains and cannot get traction on knowing whether your system actually works, that is the collaboration we are looking for.
