My background is in law and computer science,
with interests in intellectual property,
trade, international relations,
computer security, and philosophy.

A few things I like:
XKCD by Randall Munroe
Interactive Bayes Simulator by Nikita Skobelevs
Anki by Damien Elmes
Solarized by Ethan Schoonover
Old genre films


Experiments and drafts:
Training models at cipher identification for cryptanalysis (link)
- In order to study the impact of hyperparameters, I expanded the system to automatically train suites of LSTM models in bulk, hundreds or thousands at a time, each with slightly different configurations,
- That created a new problem, how do I compare all these models to understand what settings had the most impact on performance
- So I built a bespoke visualiztion tool to help quickly see and understand the exact impact of various changes to the training data and the hyperparameters
- Cipher identification is a great problem for learning about model performance and tuning because labeled training data is trivial to generate
- Early findings indicate LSTMs are often robust at distinguishing many classical ciphers with minimal training, though can struggle when learning to distinguish multiple categories all in one model
