Speech Title: "Computational Dissection of Cell-Type Heterogeneity in Single-Cell and Bulk-Tissue Populations"
Abstract: In this talk, I will describe two computational methods we have developed to tackle challenges posed by cell-type heterogeneity, one at the bulk-tissue level and the other at single-cell resolution. Due to cost reasons, almost all biomedical DNA methylation data is generated at the bulk-tissue level. Thus, to draw inferences of DNA methylation changes at cell-type resolution requires cell-type deconvolution algorithms. I will describe our efforts to build a DNA methylation-atlas for arbitrary tissue-types, which, in conjunction with specific statistical algorithms, allows detection of cell-type specific DNA methylation signals in large-scale epigenome studies. I will highlight how we have used this DNA methylation atlas to reveal cell-of-origin and novel prognostic classes of various cancer-types. In the second part of the talk, I will describe a network-entropy based modelling approach for estimating stemness and differentiation potential from single-cell RNA-Seq data, and how it can be used to identify precancerous cells of high stemness and cancer-risk in the context of esophageal cancer development.

Speech Title: "Deep Learning Methodologies in Robot Intelligence for Natural Object Manipulation"
Abstract: In the era of artificial intelligence (AI), robot intelligence is an exciting interdisciplinary field that includes robotics, machine learning, pattern recognition, and visuomotor/sensorimotor controls. The aim of robot intelligence for grasping and manipulating objects is to achieve the dexterity of grasping and manipulation in humans. Recently, advancements in machine learning methods, particularly deep learning, have accelerated the growth of this new discipline, such that robots can learn to grasp and manipulate various objects autonomously, similarly to humans. In this talk, various deep learning and deep reinforcement learning methodologies for natural object manipulation with an anthropomorphic robot hand will be presented.

Speech Title: "Privacy-preserving Computation Empowered Medical Data Sharing and Collaboration"
Abstract: Healthcare big data is fostering a huge market, bringing technological advancement or value transformation. At the same time, there are new challenges that come with it: when individual’s healthcare data are brought together, it may become a "magic mirror", telling the master behind it, such as who are you, where are you, or even more secrets about you. Since you share a part of the common genomes with your immediate family member, the disclosure of your personal medical and genetic information may also have a negative impact on the privacy of them. Therefore, it is imperative to protect the privacy of biomedical big data. Sufficient protection is necessary to safeguard patient privacy and to increase public trust in healthcare research. In this presentation, we will first review the existing challenges of healthcare data privacy. Then, we will discuss both policies and technological solutions to regulate and safeguard healthcare data privacy, respectively. Regarding policy, we will cover the Health Insurance Portability and Accountability Act (HIPAA) in US, General Data Protection Regulation (GDPR) in EU, and Network Security Law of the People's Republic of China. Regarding technological solutions, we will discuss data de-identification method under HIPAA and the risk assessment strategies of the HIPAA safe harbor rule based on large-scale Chinese healthcare data. Then, we will introduce homomorphic encryption, federated learning and differential privacy technologies for healthcare data privacy protection. More specifically, we will focus on the studies of privacy-preserving federated learning technologies in both structure and non-structure data under horizontal and/or vertical partition paradigms. Through this presentation, audience are able to become familiar with both regulatory and technological progresses in healthcare data privacy protection.

Speech Title: "Neural Activity Decoupling and Modulation Observed in Brain-Machine Interface Learning"
Abstract: In typical brain-machine interface (BMI) studies, the activities of the neuron population serve as direct input to the BMI decoder. In this study, we first trained the monkey to control the cursor to perform the center-out task smoothly with two direct units randomly selected. At the same time, we investigated how the direct units changed during BMI learning to explain how monkey learns to control the cursor. During training, these two direct units displayed a new activity pattern. They slowly changed their preferred directions until the angle between their preferred directions approached 90 degrees, which suggested that the direct units became independent of each other after BMI learning. We further investigated the activities of the neural population after the BMI learning with different numbers of direct units. We found that the direct units tended to enhance their encoding stability and increase neural modulations when the number of direct units decreased. The changes and differences observed in the neural activities in this study suggested that BMI learning could be achieved through the plasticity of the neural population.

Speech Title: "Optical Flow-based Algorithm Analyses to Detect Human Emotion from Eye Movement-Image Data"
Abstract: One of the popular methods for the recognition of human emotions such as happiness, sadness, and surprise is based on the deformation of facial features. Motion vectors that show these deformations can be specified by the optical flow. In this method, for detecting emotions, the resulted set of motion vectors is compared with a standard deformation template caused by human emotional changes. In this paper, a new method is introduced to compute the quantity of likeness to make decisions based on the importance of obtained vectors from an optical flow approach. The current study uses a feature point tracking technique separately applied to the five facial image regions (eyebrows, eyes, and mouth) to capture basic emotions. Moreover, this research will be focusing on eye movement regions. For finding the vectors, one of the efficient optical flow methods is using the pre-experiment as explained further below.
