Sometimes I like to put my thoughts into words. Here's a collection of my thoughts in some of the topics I care about.

Why the First Token Matters More Than the 10,000th

In autoregressive language models, not all tokens are created equal. The first tokens in a context window shape everything that follows — from attention patterns to generation trajectory. This is why short sessions beat long ones, and why compression exists.

Prima AI: When a Brain MRI Takes Seconds, Not Days

A University of Michigan foundation model called Prima can read a full brain MRI and diagnose across 52 neurologic conditions in seconds — reaching up to 97.5% accuracy. Here is why this matters for patients, radiologists, and the future of medical imaging.

WAPrFX: A protocol to derive simple signals from complex heart-rate data and its application to train an AI model to predict wether the signal contains anomalies or not.

Deep Learning has been the choosen tool to analyze complex data in many fields. Heart anomalies is no exception. There is a plethora of articles working on deep learning models capable of identifying anomalies in heart-rate data. This article present a different approach: instead of working with the raw data, we will process the signal to extract a simplified one that will contain enough information to train a simple model to identify anomalies. This approach will allow the simple signal to be recreated using other sensors and monitoring tools that won provide ECG data.
