Faced with the Winter of AI in early 1990's, Dr. Cha moved to the field of in-memory database management since he joined Seoul National University in 1992. To scale up his early university research, he founded a startup Transact In Memory, Inc., in Silicon Valley in 2002. The German software company SAP AG acquired this startup in late 2005. Since then, he led the conception and development of HANA, the world's first enterprise-scale in-memory database platform which finally became available in the global market in 2012.
Before HANA, disks and SSDs were used as the primary storage of large-scale enterprise database. Running big analytics and machine learning was very slow and real-time processing was impossible because the substantial volume of data must move from slow external storage to computer’s DRAM. Leveraging advances in DRAM and multi-core CPU, HANA changed the industry paradigm by using DRAM memory as the primary storage of database and providing innovative software mechanisms of fast database recovery and parallel real-time run of big analytics and machine learning inside the database platform.
Today, HANA is used by more than 17,000 companies in the world such as Apple, Walmart, Toyota, CVS Health Corporation, and Samsung Electronics. It is also available as a database service on Google, Amazon, and MS clouds. With the success of HANA, the era of in-memory computing has begun. This paradigm shift of using large memory in computing contributed to the growth of the Korean semiconductor industry.
Dr. Cha is a researcher, innovator, and entrepreneur who not only led the paradigm shift of an industry dominated by big companies but also created a new model of scaling academic research to market-disruptive innovation. With this experience, he founded a new Graduate School of Data Science at Seoul National University to educate future innovators with challenging spirit.

Controlling Knowledge in a Language Model (45분)
Large language models are known to be capable of storing a vast amount of the world knowledge. In this talk, I will discuss how we can add or update knowledge in a language model in a controlled manner without causing catastrophic forgetting. More specifically, I will present three recent projects on this topic (Continual Knowledge Learning, TemporalWiki, and Prompt Injection) and make an argument about what works and what is next.

Opportunities and Challenges in AI-Driven Drug Discovery and Development (45분)
The process of developing a new drug is long and difficult. In general, it takes more than 10 years of R&D period and 2.6 billion dollars of R&D costs before a single drug is approved. The bigger problem is that these costs are increasing every year. Some domain experts warn that if this trend continues, the pharmaceutical industry will become an industry with no ROI in a few years. In the pharmaceutical sector, there is a lot of interest in introducing AI to improve the chronic high cost and low efficiency structure of this industry. Can AI help solve this problem? AI has shown promise in many problems in the process of drug development, but I think there are still many areas lacking to show practical results. This talk outlines the drug development process from target identification, hit discovery, lead optimization, and clinical trial design, and discusses the contribution of AI at each stage and the challenges that current AI technology has to solve.

Recent advances in time-series analysis and anomaly detection (45분)
Unsupervised methods have been developed for anomaly detection because it is hard to obtain anomaly labels in practice. But, their performances are limited due to the absence of labels. This talk first introduces different approaches to overcome the limitation of anomaly detection using PU learning or weakly supervised learning. After that, this talk moves to the topic of time-series analysis. A critical challenge in time-series analysis is it is hard to get labels for segmentation or anomaly detection. I will present a technique for automatically segmenting time-series while maximizing classification performance. After that, I will present a time-series anomaly segmentation technique without segmentation labels. These works are published in AAAI2021 and ICCV2021.

A Deep Dive into 2d and 3d Human Pose Estimation (45분)
Humans are born to move; we move for physical activities in our daily life and also for communication to convey our thoughts, emotions, and intentions through a concert of subtlest movements. However, despite advances in machine perception, machines are still unable to discern the subtle and momentary nuances of human behaviors that carry tremendous amounts of information and context. In this talk, I will give an overview on 2D and 3D human pose estimation fields. I will first begin with classic and recent trends in estimating human poses in 2D. I will also delve into the various directions in 3D human pose estimation.

Towards Solving Complex Physical Tasks Via Learning Methods (45분)
Many robotics tasks, even seemingly simple procedural tasks like assembly and cleaning, require a continuous cycle of planning, learning, adapting and executing of diverse skills and sub-tasks. However, deep reinforcement learning algorithms developed for short-horizon tasks often fail on long-horizon tasks -- suffering from high-dimensionality of inputs and sample complexity. It is thus hard to scale and generalize learning agents to long-horizon complex tasks. To this end, my research centers on enabling autonomous agents to perform long-horizon, complex physical tasks. More specifically, I focus on how complex robotics tasks can be addressed by modularizing long-horizon tasks into multiple sub-tasks and skills; and address the following three main challenges: (1) how to generalize policies and reinforcement learning algorithms, (2) how to compose learned skills for a long-horizon task, and (3) how and what to learn from demonstrations. In this talk, I will describe some recents works from my lab and discuss future directions.

Deep Semi-Supervised Learning (45분)
Recently, deep semi-supervised learning attracts a lot of attentions because supervised learning approaches usually require huge amounts of labeled samples. Semi-supervised learning approaches try to utilize unlabeled samples together with labeled samples. In this talk, recent advances in deep semi-supervised learning will be overviewed, and some important issues, such as deep semi-supervised learning with extremely scarce labeled samples and how to overcome the confirmation bias in deep semi-supervised learning, are discussed.

Neural Bootstrapper and its Applications to Neural Processes (45분)
Bootstrapping 은 통계학과 머신러닝에서 uncertainty quantification 에 많이 사용되는 방법론입니다. 그러나 기존 bootstrap sampling 방식은 neural network 의 예측 분포를 학습할 때 지나치게 많은 연산량과 메모리를 요구하며, 데이터 사이즈가 커지는 경우 일부 데이터를 관찰하지 못하는 문제가 발생하게 만듭니다. 이러한 문제들을 해결하기 위해 제안된 Neural Bootstrapper (NeuBoots) 방법론과, Neural Process 를 bootstrapping 하는 응용 방법도 같이 소개합니다.
