The question

How can we speed up the research process?

[The gap:]

Approach

From raw signal to causal claim, in four stages.

[The pipeline: pre-processing biometric streams, K-Means clustering on behavioral features, regression to depression outcomes, LiNGAM to test directionality.]

Method diagram
What I found

Sleep and steps — not heart rate — drive the signal.

[Key finding: sleep duration and daily step count emerged as the strongest behavioral predictors. LiNGAM revealed direct (not just correlational) paths to depression risk.]

Result chart
What I learned

Causal claims need humility, and structure.

[Reflection: where the method held up, where it didn't, and what it would take to take this from research to a real product.]
