Speech Title: "Network Physics Approaches for Single-cell Omics and Personalized Medicine"
Abstract: Single-cell omic data continue to advance our understanding of fundamental molecular biology and to offer new strategies for personalized medicine. In this talk, I will describe a number of recent computational methods we have developed which have led to novel insights into cellular priming, aging and cancer development. One method called ELVAR addresses the challenge of testing for differential abundance of cell-types, by using cell-attribute aware clustering on the single-cell manifold which improves the sensitivity to detect differential abundance of cell-types. An application to single-nucleus RNA-Seq data reveals increased stem-cell fractions in colonic polyps, paving the way for single-cell based personalized cancer risk prediction. In the second part of the talk, I will describe methods for inferring differentiation activity of transcription factors (SCIRA) and for detecting priming events in multipotent cell populations (DICE). In the context of aging, SCIRA reveals cell-type specific patterns of age-associated changes of transcription factors that transcend tissue-type. In the context of priming, I demonstrate how primed cells and the transcription factors implicating in their priming to specific downstream cell-fates are detectable using only transcriptomic data without the need for single-cell epigenomics (scATAC-Seq data).

Speech Title: "Learning Uncertainty in Image Understanding"
Abstract: There are many questions to answer in image interpretation and understanding. Uncertainty in image analysis needs strong and powerful modelling tools to describe the objects in the images. Artificial intelligence (AI) plays a very important role in the design of a robust tool for image representation. Using some examples from his own work on uncertainty analysis, Prof. Zhou will explore how AI can stimulate new concepts or development of dealing with complicated problems and lead us to novel adventures through these applications.

Speech Title: "Scaling Multi-Instance Support Vector Machine for Cancer Detection Using Large-Scale Histopathological Images"
Abstract: Breast cancer is a type of cancer that develops in breast tissue, and, after skin cancer, it is the most commonly diagnosed cancer in women all over the world. Given that an early diagnosis is imperative to prevent breast cancer progression, many machine learning models have automated the histopathological classification of the different types of carcinomas. However, many of them are not scalable to the large dataset. In this study, we propose the novel Primal-Dual Multi-Instance Support Vector Machine (pdMISVM) to determine which tissue segments in an image exhibit an indication of an abnormality. We also derive the efficient optimization approach for the proposed method by bypassing the quadratic programming and least-squares problems, which are commonly employed to optimize Support Vector Machine (SVM) models in multi-instance learning. The proposed method is scalable to large datasets, and it is computationally efficient. We applied our method to the public BreaKHis dataset and achieved promising prediction performance and scalability for histopathological classification.

Speech Title: "Study on Noninvasive and High-Density Precision Heart Lesion Localization Method"
Abstract: Ectopic excitation of the heart can trigger arrhythmia. At present, catheter ablation has been widely used in the treatment of arrhythmias, but it has limited effect on some arrhythmias. The inaccurate and incomplete location of the ectopic excitation points that trigger arrhythmia during the operation leads to the high recurrence rate after catheter ablation. Preoperative noninvasive localization of cardiac lesions is very attractive and challenging for the clinical treatment of arrhythmia. In this paper, the method of non-invasive acquisition of high-density body surface signals, localization, and visualization of ectopic focal points in the heart is studied, and a set of ectopic excitation non-invasive localization system for the diagnosis and treatment of arrhythmia is developed. Through more than ten cases of clinical testing, the results show that the method proposed in this paper has high accuracy.
