Adversarial Prediction Models for Learning-Augmented Algorithms

A position paper arguing that predictions used by learning-augmented algorithms should be treated as untrusted algorithmic inputs, not neutral estimates. Maps adversarial machine learning threat models into algorithm design and proposes benchmark dimensions for robust, security-aware online decision-making.

Spacetime as a Neural Network

In 2021, physicist Lee Smolin, Jaron Lanier, and others published a paper with a bold claim: write Einstein's general relativity in a specific form, and the equations governing spacetime curvature correspond to the equations of a Restricted Boltzmann Machine.

One Agent Isn't Enough

Agentic coding has a problem - variance. What if single-agent runs are leaving performance on the table by design?

Intelligence Without Information Is Squandered

Claude confidently pointed me to a code path in MongoDB's massive infrastructure codebase. I spent an hour investigating it before realizing something was off. The path worked, technically. But there were better approaches - ones the agent had completely missed.

The New Math of Building with AI

The sixteenth draft of my Chinese dictionary lies abandoned in a folder deep within my repo. Two weeks of work, genuinely good code, completely functional. Pre-AI me would have shipped it just to justify the time spent. Post-AI me deleted it and started building something better.
