Programme Outline

DAY 1 – 6 August 2018

Session

CS-1

Title

Hands-on Optimization of CPU and FPGA Designs with a Modern Computer Architecture Overview

Speaker

Trevor E.Carlson

Assistant Professor, Dept of Computer Science

Venue

Video Conference Room (COM1-02-13)

Abstract

While computers continue to advance in performance today, the near future will bring challenges for computing. We can no longer continue to add additional transistors to our processors as the costs have begun to rise (Moore’s Law is ending). We can no longer turn on more transistors at the same time because our processors are getting too hot (Dennard Scaling is ending). To address these problems, computer architects have turned their focus to efficiency, a departure from previous years' efforts of performance at all costs.

The goal of this course is to provide a preview of some of the state-of-the art techniques developed today to address energy and area efficiency challenges in computer architecture. We will focus on developments that apply to today’s devices, from watches to smartphones, as well as desktops and servers. More specifically, this class will begin from the transition to multi-core technologies, discuss energy-efficient techniques that allow these general-purpose architectures to improve, and finally, describe the latest techniques and architectures, like the focus on memory-level parallelism (MLP), load-slice processors and out-of-order commit processors as well as FPGA accelerators.

In the second half of this course, we will conduct a hands-on coding and optimization playground. We will take a deep-dive into the latest software computer architects use to design next generation processors and accelerators. In small groups, participants will choose from a number of platforms and tutorials to learn how to become the computer architects of the future. Students can focus on one or two platforms, and work in-depth to improve state-of-the-art designs, or take a broader view, and work through the basic tutorials for each platform to understand how each platform contributes in different ways. Example platforms include optimization of Machine Learning algorithms on personal Xilinx PYNQ FPGAs, and experimenting with the Sniper Multicore Simulator to evaluate next-generation IoT and server applications.

At the end of the second half, each student group will give a short presentation on one of the topics they found interesting during the hands-on session, and explain its connection to computer architecture and the future of computing.

Title

Gaussian Process Methods in Machine Learning

Speaker

Jonathan Scarlett

Assistant Professor, Dept of Computer Science

Venue

Seminar Room 3 (COM1-02-12)

Abstract

I will provide an introduction to a powerful tool in modern machine learning and statistics known as Gaussian Processes (GPs). This is a rich and versatile class of probabilistic models for modelling input-output relationships in data, with recent successful applications including tuning deep neural networks, optimising robot parameters, modelling environmental data, and more. In contrast with parametric methods that assume a very specific type of underlying relationship (e.g., a linear function), GP methods can directly model more complex relationships in a principled manner. I will introduce GPs in the context of regression, i.e., learning an entire input-output relationship of the form y = f(x) based on samples of (x,y) pairs. I will then move onto more recent developments in Bayesian optimisation, where one adaptively samples in order to search for an input maximising the underlying function f(x).  I will also discuss some of the main ongoing challenges in the field, including scaling to large data sets, and handling "high-dimensional" scenarios with a very large number of input variables.

Title

Biometrics Authentication

Speaker

Terence Sim
Associate Professor, Dept of Computer Science

Venue

Seminar Room 9 (COM1-02-09)

Abstract

Biometrics is increasingly being used for authentication, eg. fingerprint for phone payment, face recognition for door access. But how does biometrics work? What are the challenges? This one-day course will give an overview of the different types of biometrics, examine their pros and cons, and introduce the concepts of pattern recognition that underlie all biometrics authentications. A hands-on session will be conducted for you to experiment with pattern recognition.

Title

Understanding the Dynamics of a Digital Platform Ecosystem: Application of Network Analysis and Deep Learning

Speaker

Um Sungyong

Assistant Professor, Dept of Information Systems and Analytics

Venue

Seminar Room 10 (COM1-02-10)

Abstract

Digital platform ecosystems are dynamic: they grow and evolve as new firms join the ecosystems. However, the way digital platform ecosystems change is not clearly understood. Qualitatively, this course introduces the two basic conceptual approaches to understand the structure of a digital platform ecosystem. Quantitatively, this course draws on computational statistical methods to capture the structural change of a digital platform ecosystem. First, from the perspective of deep learning, this course introduces the way that deep learning techniques such as Word2Vec are used to sort out network information from various resources such as firm documents and application source codes. Second, from the perspective of network analysis, this course focuses on interactions of which form a complex bipartite network that drive the changes in the topological structure of a digital ecosystem over time. In particular, changing combinations of existing digital components such as APIs and software packages in applications are focused on to capture the dynamics of a digital platform ecosystem.

Title

Security Challenges and Solutions of the Internet and its Things 

Speaker

Kang Min Suk and Han Jun

Assistant Professors, Dept of Computer Science

Venue

Video Conference Room (COM1-02-13)

Abstract

The Internet has evolved at a fast pace in the past few years and embraced numerous emerging networks, including Internet of Things, 5G, and blockchain networks. At this exciting moment of rapid transformation, unfortunately, we have faced new security challenges in the newly expanded attack surface. In this lecture, we will discuss security challenges in (1) designing highly available next-generation Internet, (2) secure operation of large numbers of Internet of Things devices, (3) fixing vulnerabilities in 5G LTE systems, and (4) designing secure and private blockchains. Our work has addressed several fundamental questions of these security problems, often utilizing new security primitives. The lecture may have some hands-on sessions, and thus students are encouraged to bring their laptops to enjoy the demonstrations.

Title

Privacy in the Age of Machine Learning

Speaker

Reza Shokri

Assistant Professor, Dept of Computer Science

Venue

Seminar Room 3 (COM1-02-12)

Abstract

What does digital privacy mean? What is anonymity? How can a computer scientist reason about privacy in a quantitative manner? What can a curious entity learn about our sensitive information in a computing system? Is it possible to share our data without risking our privacy? What are the risks of releasing aggregate statistics or machine learning models? How can we protect data privacy? What is the role of encryption and randomization?

I will provide an algorithmic framework for answering these questions for real applications. I will talk about how to assess privacy risks and to guarantee privacy in various computing systems including machine learning. Basic probability and algorithms are the pre-requisites for this course.
