CUHK + UniMelb = Fable-based Learning + A Tale of Two Cities

Prof Jimmy Lee, Chinese University of Hong Kong

This talk reports on the pedagogical innovation and experience of a joint venture by The Chinese University of Hong Kong (CUHK) and the University of Melbourne (UniMelb) in the development of MOOCs on the computer science subject of “Modeling and Solving Discrete Optimization Problems”.  In a nutshell, the MOOCs feature the Fable-based Learning approach, which is a form of problem-based learning encapsulated in a coherent story plot.  Each video lecture begins with an animation that tells a story based on the Chinese classic “Romance of the Three Kingdoms”, in which the protagonists in the novel encounter a problem requiring technical assistance from the two professors from modern time via a magical tablet bestowed upon them by a fairy god.  The new pedagogy aims at increasing learners’ motivation as well as situating the learners in a coherent learning context.  In addition to scriptwriting, animation production and situating the teaching materials in the story plot, another challenge of the project is the remote distance and potential cultural gap between the two institutions as well as the need to produce all teaching materials in both (Mandarin) Chinese and English to cater for different geographical learning needs.  The MOOCs have been running recurrently on Coursera since 2017.  Some learner statistics and feedbacks will be presented.  The experience and preliminary observations of adopting the online materials in a Flipped Classroom setting at CUHK will also be detailed.

This video at Youtube shows the trailer for the Coursera Course:

Why Homotopy type Theory (HoTT) matters – Professor Thorsten Altenkirch

Event details

  • When: 25th May 2018 11:00 - 12:30
  • Where: Cole 1.33a
  • Format: Seminar

Abstract:
Dependent types are a wonderful way to construct correct functional programming and specify interfaces as Edwin has shown in his nice book on type driven development using a welsh dragon. But shall we go further in the esoteric world of homotopy type theory? I will try to motivate this and I am looking forward to some discussions with people who have a more pragmatic attitude to dependent types.

SACHI Seminar: Alessio Malizia – User Experience: a step towards Natural User Interfaces.

  • When: 7th June 2018 14:00 - 15:00
  • Where: Cole 1.33a
  • Format: Seminar

Title: User Experience: a step towards Natural User Interfaces.

Abstract: The road to natural interfaces is still long and we are now witnessing an artificial naturality. These interfaces are natural, in the sense they employ hand gestures, but they are also artificial, because the system designer imposes the set of gestures. In this lecture we will explore together the benefits and issues of Natural User Interfaces.

Speaker biography: Alessio Malizia is a Professor of UX Design at the University of Hertfordshire and a distinguished speaker of the ACM (the international Association for Computer Machinery); he lives in London but is a “global soul” and has been living in Italy, Spain and US. He is the son of a blacksmith, but thereafter all pretensions of manual skills end. Prof. Malizia began his career as a bearded computer scientist at Sapienza – University of Rome and then, after an industrial experience in IBM and Silicon Graphics, moved on with a career in research. He was visiting researcher at the Xerox PARC where he was appreciated for his skills in neural networks (Multilayer Perceptrons) and as peanut butter and chocolate biscuits eater. He worked as Senior Lecturer at Brunel University London and as Associate Professor (and Spanish tapas aficionado) at the University Carlos III of Madrid. Prof Malizia’s research and teaching interests focus on Human-Centred Systems.

He is interested in the design of Ubiquitous Interactive Systems with a special focus on the End-User Development community. He is particularly interested in systems where the physical and digital become seamlessly intertwined producing a new hybrid landscape and the study of problems arising from designing such complex hybrid environments involving collaboration of various disciplines and stakeholders. In his role at the School of Creative Arts at University of Hertfordshire, he is keen to develop novel approaches and attract funding for improving methods to design almost invisible interfaces embedded in a physical environment naturally exploited by users’ innate interaction modalities.

SRG Seminar: “Application of Bayesian Nonparametric in household human activity recognition” by Lei Fang

Event details

  • When: 12th April 2018 13:00 - 14:00
  • Where: Cole 1.33b
  • Series: Systems Seminars Series
  • Format: Seminar

Abstract

In this talk, I will talk about the possibility of using Bayesian nonparametric clustering, or Dirichlet Process Mixture model to solve human activity recognition problem. In particular, I will discuss how the technique can be useful when the activity labels are not annotated and/or the activity evolves over the time. This initial study is built on an existing work on using directional statistical models (von Mises-Fisher) distribution, called Hierarchical Mixture of Conditional Independent von Mises Fisher distribution (HMCIvMFs), for unknown events detection and learning. Markov chain Monte Carlo sampling based learning algorithm will be presented together with some initial experiment results.

Abstract
Data processing paradigms are undergoing a paradigm shift as we move more and more towards real time processing. Emerging software models such as the SMACK stack are at the forefront of this change, focused on a pipeline processing model, but are also introducing new levels of operational complexity in running multiple complex distributed systems such as Spark, Kafka and Cassandra. In this talk, I’ll introduce both Apache Mesos and DC/OS as a solution to this growing problem, and describe the benefits are of running these new kinds of systems for emerging cloud native workloads.

Diderot: A Parallel Domain-Specific Language for Image Analysis and Visualization

Abstract:
The analysis of structure in three-dimensional images is increasingly valuable for biomedical research and computational science. At the same time, the computational burden of processing images is increasing as devices produce images of higher resolution (e.g., typical CT scans have gone from 128^3 to roughly 512^3 resolutions). With the latest scanning technologies, it is also more common for the the values measured at each sample to be multi-dimensional rather than a single scalar, which further complicates implementing mathematically correct methods.

Diderot is a domain-specific language (DSL) for programming advanced 3D image visualization and analysis algorithms. These algorithms, such as volume rendering, fiber tractography, and particle systems, are naturally defined as computations over continuous tensor fields that are reconstructed from the discrete image data. Diderot combines a high-level mathematical programming notation based on tensor calculus with an abstract bulk-synchronous parallelism model. Diderot is designed to both enable rapid prototyping of new image analysis algorithms and high performance on a range of parallel platforms.

In this talk, I will give an overview of the design of Diderot and examples of its use. I will then describe aspects of its implementation with a focus on how we translate the notation of tensor calculus to efficient code. I will also briefly discuss the automated techniques we use to validate the correctness of the compilation process.

Diderot is joint work with Gordon Kindlmann, Charisee Chiw, Lamont Samuels, and Nick Seltzer.

SRG Seminar: “On Engineering Unikernels” by Ward Jaradat

Event details

  • When: 15th March 2018 13:00 - 14:00
  • Where: Cole 1.33b
  • Series: Systems Seminars Series
  • Format: Seminar

We have explored data coordination techniques that permit distributed systems to be constructed by interconnecting services. In such systems the network latency is often a problem. For example, large data volumes might have to be transmitted across the network if computation cannot be co-located close to data sources. One solution to this problem is the ability to deploy services in appropriate geographical locations and compose them together to create distributed ecosystems. Hence we seek to be able to deploy such services rapidly and dynamically enact and orchestrate them. However, this goal is hindered by the size of the deployments. Currently, virtual machine appliances that host such services on top of monolithic kernels are very large, thus are potentially slow to deploy as they may need to be transmitted across a network.

Our principles led us to take the route of re-engineering the standard software stack to create self-contained applications that are less-bloated and consequently much smaller based on Unikernels. Unikernels are compact library operating systems that enable a single application to be statically linked against a simple kernel that manages the underlying resources presented by a hypervisor. In this talk I will present Stardust – a specialised Unikernel that aims to support the deployment of application services based on the Java programming language.

SACHI Seminar – Large scale studies of habit changing interface design

Speaker: Matjaž Kljun

Abstract:

Various technologies can be used in persuading people to change their habits, behaviours or attitudes. Such technologies are defined as persuasive and they are used in a variety of fields such as marketing, public health and education.

We are daily exposed to persuasion through different visualizations and triggers on all our devices. For example, a social networking application tries to persuade us in opening the app with a push notification and once the app is opened other hooks are placed so we spend more time in it. However, such applications are usually installed by us and we are inclined in using them. But could we persuade highly busy professionals in completing a training course or just about everybody to read terms of service? We will discuss these issues through large-scale studies that have been in done in the wild.

Speaker biography:  Matjaž Kljun is an assistant professor at the Faculty of Mathematics, Natural Sciences and Information Technologies at University of Primorska and is co-directing the HICUP lab (Humans Interacting with Computers at University of Primorska) and a research associate at the Faculty of Information studies, Slovenia. He received his Ph.D. degree in computer science from Lancaster University, UK. His research interests span across various fields related to Human-Computer Interaction, Personal Information Management and the use of technologies in teaching and learning.
