Statistical Methods for In-session Hemodialysis Monitoring
… dialyzates at different time in one session. Baseline correction being a critical procedure in use of Raman Spectra, existing methods may not perform well on dialysis spectra due to nature of dialyzates, which contain numerous chemicals compounds. We first developed a new baseline correction …

From Intention to Action: Neural Dynamics of Voluntary Action
… classification did so by classifying against a baseline window which can lead to spurious early classification in autocorrelated event-locked data. In a second study, I explore how baseline correction in the neuroscience of volition can distort early signals, modulating both their apparent …
