Abstract Gas pollutants have been increasing released since the industrial area has been expanded every years. Based on the World Health Organization (WHO) report, 9 out of 10 people breathe air containing high levels of pollutants and around 7 million people die every year from both outdoor and household air pollution. Therefore, the real-time detection of emitted toxic gases is still important for protection of short- and long-term effects on human health. Although, several toxic gas detector devices are available in markets yet, they are very expensive, big, offline, and no wearable device. Therefore, most of people cannot use them in daily life. In this work, I will present new smart gas sensor technologies combined with machine learning and Internet of Things (IoT). The talk will be carried out all aspects of internet of gas sensing things ranging from design of sensing materials to targeted gas molecules based on self-consistent charge density functional tight-binding (SCC-DFTB), synthesis of sensing nanocomposites, fabrication of gas sensors to integration with machine learning and IoT system into the smart devices to use in real-world applications.

Abstract. AI can be defined as H/W and S/W technology with data processing that imitates the human brain. Advanced AI (learning and reasoning) requires massive data storage and transmission. Conversely, it requires low data transmission energy for low power consumption and low cooling costs in a viewpoint of TCO (Total Cost Ownership). (Cooling cost example: Google Dallas data center accounts for 1/4 of Dallas city water use, The memory semiconductors in AI era can be developed on two track keywords. The first is integration, which is the combination of heterogeneous chips for learning and reasoning functions. For example, CXL-based next-generation memory and computational chip combined HBM. Second is interconnection. The interconnection in chip and between chips will be used for very fast and low-energy data transmission (example: Through Silicon Via, Through Hole Via, Cu-to-Cu Bonding etc.). Through this presentation, we would like to introduce innovatoin of future memory for various application: servers, datacenters, self-driving cars, and individual devices.

Abstract Deep learning techniques use multi-layer (“deep”) neural networks (DNNs) to learn representations of data with multiple levels of abstraction. These techniques can discover intricate structure in a dataset by using a back-propagation algorithm to set the internal parameters that are used to transform data as they flow between network layers. We have applied deep learning methods to accelerate various science applications including ones from light sources and climate science. In this talk, I will provide an overview of this work. We have also developed systems such as FairDMS (Findable, Accessible, Interoperable and Reusable Data and Model Service) and FreeTrain (A Framework to Utilize Unused Supercomputer Nodes for Training Neural Networks) to accelerate deep learning training. I will discuss these systems as well in my talk.
