Functional principal component analysis (FPCA) on remote sensing data and longitudinal studies

open access: gold, 2021
This dissertation consists of three main pieces of my Ph.D. dissertation, which shapes my research on multivariate functional data, change-point detection, asynchronous longitudinal data, and remote sensing data applications. The first project is motivated by NASA's first dedicated \ce{CO2} monitoring satellite, the Orbiting Carbon Observatory-2 (OCO-2)

Using functional principal component analysis (FPCA) to quantify sitting patterns derived from wearable sensors [PDF]

open access: goldInternational Journal of Behavioral Nutrition and Physical Activity
Abstract Background Sedentary behavior (SB) is a recognized risk factor for many chronic diseases. ActiGraph and activPAL are two commonly used wearable accelerometers in SB research. The former measures body movement and the latter measures body posture.

Functional principal components analysis via penalized rank one approximation [PDF]

open access: yes, 2008
Two existing approaches to functional principal components analysis (FPCA) are due to Rice and Silverman (1991) and Silverman (1996), both based on maximizing variance but introducing penalization in different ways.

Exploiting upper-limb functional principal components for human-like motion generation of anthropomorphic robots

open access: yesJournal of NeuroEngineering and Rehabilitation, 2020
Background Human-likeliness of robot movements is a key component to enable a safe and effective human-robot interaction, since it contributes to increase acceptance and motion predictability of robots that have to closely interact with people, e.g.
