NeuroFlow

I’m building NeuroFlow, an AI project that tries to predict how Alzheimer’s disease changes over time using real TADPOLE/ADNI patient data. The model looks at a patient’s past visits, including cognitive scores, diagnosis, and brain-imaging biomarkers like hippocampus and ventricle volume, and tries to predict what might happen at a future visit. Right now, I’m working on a model idea called GapFlow. Instead of making a deep model predict everything from scratch, I first use strong baseline models to predict the “expected” future, then train a time-aware Transformer to learn what the baseline missed. In my first small test, this helped improve some predictions, especially ADAS13, hippocampus, and ventricles. Eventually, I want to add actual brain scan representations so the model can predict possible future MRI changes too.

This week NeuroFlow finally went from just being an idea to something actually real. I got it set up with the TADPOLE Alzheimer’s data and made sure the model only sees past patient visits when predicting future ones, so there’s no accidental cheating by peeking at data it shouldn’t have. I also cleaned up the Git repo, locked down the raw medical data with .gitignore, and got a safe first commit in. My biggest realization this week was that the simple baseline models are honestly really strong for Alzheimer’s prediction, since a lot of the biomarkers change pretty slowly over time. So instead of forcing some fancy deep model to beat them head-on, I flipped the whole approach. Now the deep model just learns the gap between the baseline prediction and the real future outcome, which is way smarter than brute-forcing it.I wrapped up Phase 1 by creating the baseline predictions and residual targets, then built Phase 2: a residual time-aware Transformer that looks at past visits, time gaps, and baseline predictions all together. Even in a tiny 300-patient test run it already improved ADAS13, hippocampus, ventricles, and slightly whole-brain volume, which felt really good. Next up I want to push it on a bigger run and then compare it against a residual Neural CDE. Wish me luckk!
