Speech Title: "Data-driven Drug Discovery and Healthcare by Machine Learning"
Abstract: In recent years, drug discovery has become increasingly difficult. Computational approaches are expected to promote the efficiency of drug development processes. Recent developments in biotechnology have contributed to the increase in the amounts of high-throughput data in the genome, transcriptome, proteome, interactome, phenome and diseasome. These biomedical big data can be useful resources for drug development processes. Machine learning methods are expected to play key roles in the big data analysis. In this study, we developed novel machine learning methods to predict therapeutic targets of diseases, to search for drug candidate molecules, and to design new chemical structures of drug candidate molecules, by integrating various biomedical data on compounds (e.g., chemical structures, clinical phenotypes, gene expression patterns, target molecules) and diseases (e.g., disease-causing genes, environmental factors, and clinical information). A unique feature of our data-driven approach is that it clarifies all target proteins of each drug including off-targets, estimates the mechanisms of action at the pathway level, and generates molecular structures of drug candidates by deep learning. In my talk at the conference, we will show some of the applications to therapeutic target identification, large-scale compound screening, combination therapy, and drug molecular structure design for a variety of diseases.

Speech Title: "The Applications of Deep Learning in Separation of Heart and Lung Impedance Images in Electrical Impedance Tomography"
Abstract: Electrical impedance tomography
(EIT) is a noninvasive medical imaging technique that
measures the impedance of tissues by applying
low-amplitude electrical currents and measuring the
resulting voltages. The impedance distribution inside
the body can then be reconstructed by solving an inverse
problem, which provides useful information for
diagnosing and monitoring a variety of conditions, such
as respiratory and circulatory functions. One of the
challenges of EIT in chest applications is separating
the impedance signals from the heart and lungs. This is
difficult because the two organs are close together and
their impedance signals are mixed. However, deep
learning has emerged as a promising approach to solving
this problem. Deep learning models can be trained on EIT
data to learn the features that distinguish between
heart and lung impedance. Once trained, these models can
be used to separate the two signals and produce more
accurate EIT images. In our recent study, we proposed a
novel semi-Siamese U-Net architecture for heart and lung
impedance image separation. This architecture is based
on the state-of-the-art U-Net, with modifications and
extensions to improve performance on EIT image
