Optical Coherence Tomography (OCT) is a powerful technique for non-invasive 3D imaging of biological tissues at high resolution that has revolutionized retinal imaging. A major challenge in OCT imaging is the motion artifacts introduced by involuntary eye movements. In this paper, we propose a convolutional neural network that learns to correct axial motion in OCT based on a single volumetric scan. The proposed method is able to correct large motion, while preserving the overall curvature of the retina.

Identifying uterine contractions with the aid of machine learning methods is necessary vis-á-vis their use in combination with fetal heart rates and other clinical data for the assessment of a fetus wellbeing. In this paper, we study contraction identification by processing noisy signals due to uterine activities. We propose a complete four-step method where we address the imbalanced classification problem with an ensemble Gaussian process classifier, where the Gaussian process latent variable model is used as a decision-maker.

We present CCACUSUM, a classifier for steady-state visual evoked potential (SSVEP)-based brain-computer interfaces (BCIs) that determines whether a user is attending to a flickering stimulus or is at rest. Correct classification of these two states establishes cause and effect between the BCI and its user, which is essential for helping individuals with complex communication disorders (CCDs) communicate.

With the recent advancement of the Brain-Computer Interface (BCI), Electroencephalogram (EEG) analytics gain a lot of research attention from various domains. Understanding the vulnerabilities of EEG analytics is important for safely applying this emerging technology in our daily life. Recent studies show that EEG analytics are vulnerable to adversarial attacks when adding small perturbations on the EEG data. However, fewer research efforts have been devoted to the robustness of EEG analytics under sparse perturbations that attack only small portions of the data.

Diet monitoring is an important component of interventions
in type 2 diabetes, but is time-intensive and often inaccurate. To address this issue, we describe an approach to monitor diet automatically, by analyzing fluctuations in glucose
after a meal is consumed. In particular, we evaluate three
standardization techniques (baseline correction, feature normalization, and model personalization) that can be used to
compensate for the large individual differences that exist in
food metabolism. Then, we build machine learning models

RTip is a tool to quantify plant root growth velocity using high-resolution microscopy image sequences at sub-pixel accuracy. The fully automated RTip tracker is designed for high-throughput analysis of plant phenotyping experiments with episodic perturbations. RTip is able to auto-skip past these manual intervention perturbation activity, i.e. when the root tip is not under the microscope, the image is distorted or blurred. RTip provides the most accurate root growth velocity results with the lowest variance (i.e.
