Observed that the accelerometer data (anglez) is noisy (visually and sometimes with std, <code>ruptures</code> package seems to catch that as well) outside the onset-awake window. Posting this to promote some discussion on using VAEs to model the noise, has someone already tried that? Wouldn't that be interesting..</p>\n<p><img src=\"https://www.googleapis.com/download/storage/v1/b/kaggle-forum-message-attachments/o/inbox%2F3599008%2F2ac29e1a134cd6bf87e0dc9e11f9de83%2FScreenshot%202023-10-01%20at%2015.30.56.png?generation=1696167078630565&amp;alt=media\" alt=\"\"></p>",
