Notes on investigation work, plus case files from real public datasets.
A plain-language explainer on duplicate matching. How two documents are compared value by value, what a weight is and how the score is worked out, what the two cutoffs decide, how to tune the noise away one change at a time, and what to do with a match that turns out to matter, shown on an invented firm's shared drive.
A short explainer on vectors. What an embedding is, how search by meaning works on an ordinary processor, where it stops (pictures, other languages, sounds no transcript holds), and what a model that reads pictures and sound changes, measured on an invented company's shared drive.
Free cash flow explained, then measured on every UK-listed company with a track record: 1,823 tagged annual reports from filings.xbrl.org, read year by year. Who turns profit into cash, who compounds, and what companies mean when they say free cash flow.
A decision model does not write. You give it a text and a list of questions, and it answers each with a probability. What that is, where the name System One comes from, why there are suddenly so many, and what five real models did with fifty messages to a bike shop that does not exist.
An API key in a screenshot, a .env file in an abandoned side project, a text note full of passwords. A step-by-step walkthrough of finding every leaked secret on your own laptop with one Docker command, read-only, without anything leaving the machine.
A delivery slips by two weeks and three orders hang on it. Four rescue ideas go on a case board as hypotheses, and one survives. A case file on Nova Manufacturing: an invented pump maker on a real workspace.
Every figure is correct, and the story is still wrong. We pulled real data from Destatis, the BKA and the EU into one system and went looking for the places where a true number says something false. We found six.
Three cases on Austria's company register that add and drop companies on their own as filings arrive. In their first seven hours live, they took in 123 answers without a person touching them. Here is how we built them, and what they will not claim.
See how Classifyre autonomously investigated 9,601 Hillary Clinton email files, tested 20 detectors, and opened eight evidence-backed cases.
