Don’t Just “Throw Adam at It”: Misunderstanding Adam Will Cost You
1+ mon, 2+ week ago (1737+ words) You "vibe-coded" the import. Understand Adam's optimization dynamics, why it fails spectacularly, and how to fix it. I spent weeks working on a particularly hard reinforcement learning problem. The research demonstrated similar agents learning comparable tasks. Yet our model was…...
Are Your ML Experiments a Mess? Here’s the Fix
1+ mon, 3+ week ago (843+ words) A hands-on guide to tracking experiments, logging models, and reproducing results with ML Flow. To ensure that the right models are in production, we need a way to manage various models and versions, track performance metrics, and reproduce results. This…...
Proteins: A Mosaic Pattern to Rule Them All?
2+ mon, 3+ week ago (429+ words) An introduction to the Mosaic Q model and to the tools you can use for its quantification and visualization. In the next images we see an overview of the analysis. Here is how the mosaic, its quantification via Q, and…...
I Pitted XGBoost Against Logistic Regression on 358 Matches. The Boring Model Won.
2+ mon, 2+ week ago (1244+ words) A concrete bias–variance lesson: why the smallest model had the best cross-validated fit, and how to know when to reach for the big hammer. So when I lined up five classifiers on the same task and the one-line linear…...
Structured Outputs with LLMs: JSON Mode, Function Calling, and When to Use Each
2+ mon, 3+ week ago (664+ words) Getting reliable, readable responses out of your LLM, and knowing which tool to reach for In my latest posts, we’ve talked a lot about popular techniques for optimizing the performance and cost of AI applications, like response streaming or prompt…...
RAG Was Always a Temporary Workaround. What is Next?
2+ mon, 2+ day ago (944+ words) Why the future of AI memory relies on persistent neural state, not vector databases. Look closely at your favourite RAG system. Very closely. We labelled this “memory.” A more honest name would be: a very elaborate, high-latency game of telephone…...
