AI/Data Track

13:40-14:20 The past and future of machine learning research

Machine learning (ML) technology has seen significant development in recent years, surpassing human performance in areas such as speech recognition, image analysis, and natural language translation. However, there has been less progress in application fields such as medicine and disaster prevention, where high quality labeled big data cannot be gathered easily, so there is still room for further improvement. This session will outline the history of ML research and the present state of the international ML research community. We will also introduce weakly supervised ML methods and robust ML methods developed by our group, and finally discuss where ML should go next with the audience.

14:20-15:00 Real or Fake? The Future of Media Security and Privacy

The dramatic spread of smartphones equipped with high performance sensors has enabled filming and recording of other people’s faces and voices, and even collection of large quantities of biometric data such as fingerprints and irises. These can also be shared in cyberspace, not only violating privacy but also illustrating the risk of breaches of biometric authentication. This high-quality biometric data can be used as learning data, making it easy to create high-quality fake media such as deepfakes, which may negatively impact people’s ability to make decisions. This session will outline these threats and introduce technology for users to control distribution of their own biometric data in cyberspace and technology for detecting fake media, as well as anonymization technology.

17:20-18:00 The Basics of AI Security: Attacking & Defending AI

With the rapid advancement of AI making use of machine learning, AI has become a mainstay in many fields in Japan, including facial recognition, crime prevention, and automated driving systems. Meanwhile, the methods of attacking AI have multiplied as well. Adversarial Examples cause AI to make false predictions by introducing small changes into the entered data, AI learning data can be manipulated to corrupt data and open a back door, and functions in frameworks used for AI development can be abused, thereby enabling systems to be hijacked for attacks. These have caused a rapid need for technology to defend AI, but because many of the principles governing attacks on AI differ fundamentally from those on existing systems, it is difficult to respond using old security technology, so we need defensive technologies specifically for AI. In this session, entitled “the basics of AI security”, I’ll explain the mechanisms of attacking AI, and an overview of the technologies for defending AI.

Infrastructure Track

15:40-16:20 Network Access Control using Workload Identity

Before the cloud era, network administrators assumed they could use IP address or port number as a workload identifier in network access control. Routers or firewalls were configured with rules called network ACLs containing IP addresses or port numbers for packet filtering. However, as seen in many large-scale data centers, it is becoming challenging to use IP addresses or port numbers to identify workloads in dynamic mixed environments consisting of varied workloads like virtual machines or containers on a flat IP Clos network. How can we implement efficient access control in these environments? This session introduces a packet-filtering-based access-control technology that uses workload identity, which we are proposing in association with the LINE Verda office.

17:20-18:00 Google Research on End-to-End Models for Speech Recognition

When neural networks re-gained popularity in speech recognition about 10 years ago they were mainly used for the acoustic model of the system (the model that relates the audio with phonetic units). To obtain a complete recognition system, those models would be combined with a language and pronunciation model. Due to ongoing research, recent years have shown that speech recognition systems can be built that is a singular neural network that encompasses the entire speech to text system, the so-called end-to-end systems. These models are of interest as they are compact, accurate due to their joint optimization and easy to build as there is very little need for manual design. On the other hand, in contrast to the previous systems, they have given rise to a number of research problems related to control and online operation of such models. This talk will describe some of the research Google has done to address such issues.

Day2 − Thursday, November 26

AI/Data Track

13:00-13:40 Fugaku: the First ‘Exascale’ Supercomputer for Society. 5.0

Fugaku is the first ‘exascale’ supercomputer due to its demonstrated performance in real applications, as well as reaching actual exaflops in new breed of benchmarks such as HPL-AI. But the importance of Fugaku is “applications first” philosophy under which it was developed, and its resulting mission to be the centerpiece for rapid realization of the so-called Japanese ‘Society 5.0’ as defined by the Japanese S&T national policy. As such, Fugaku’s immense power is directly applicable not only to traditional scientific simulation applications, but can be a target of Society 5.0 applications that encompasses conversion of HPC & AI & Big Data as well as Cyber (IDC & Network) vs. Physical (IoT) space, with immediate societal impact with its technologies utilized as Cloud resources. In fact, Fugaku is already in partial operation a year ahead of schedule, primarily to obtain early Society 5.0 results including combatting COVID-19 as well as resolving other important societal issues.

16:50-17:30 Open Source collaboration: from A to Z

The heart of open source is people working together for shared benefit. Sounds nice, but does that happen in real life? This session will answer resoundingly yes. We will cover different types of collaboration practice, including shared brainstorming, maintenance and stewardship. You’ll learn what communication tools are involved and what types of behaviors set up success. “Open Source collaboration: from A to Z” is a real story that continues today. We will use real events from two projects: Armeria and Zipkin, to exemplify practice that resulted in mutual gain. While these two projects are both open source, many of these practices work in any software practice. Throughout the session, consider what you work on and if there are overlaps with open source you consume. Perhaps when you leave, you will know how to not just give back, but improve your collaboration skills at the same time!

16:50-17:30 Get the Most Out of Your Product Manager

CEO of the Product. Product “owner”. “The Business”. With terms like these, it is no wonder that the relationship between Product Managers and Engineers can be contentious at times. Better products get built when teams are collaborating and working together across disciplines. Product managers and engineers provide needed balance to each other. But too often the balance gets shifted and an “us vs them” mentality emerges. The lack of trust erodes collaboration and keeps teams from operating at a high-performance level. This talk aims to address some common misconceptions about product managers, and discuss how product managers and engineers can work better together to reach a common goal – building products people love.
