Working Notes
The running series
Status of This Document
The complete series, newest numbers last. Notes are numbered in the order they were written, not grouped by subject, so a research note and an engineering note may sit next to each other. Index pages, including this one, are not numbered; a number marks a document, not a list of them.
Building Reliable Intelligent Systems
The self-description: the standards I work to, the evidence for them, and the question underneath all of it.
Reconstruction Under Missing Data
An attention-gated U-Net that gave the largest uncertainty reduction of nine methods tested, and the measure on which it lost to something simpler.
A Model That Did Not Work
A time-aware neural ODE that reconstructed well, could not report its own uncertainty stably, and ended up in an appendix.
A Website With Rules
This site as an engineering problem: the constraints, the one that had to bend, and the four errors the rules caught before a reader could.
Short technical pieces, papers read and bugs that taught something, will accumulate here alongside the longer notes. Per §1.6 of WN-001, work not written down should be treated as lost.
