The first talk on data privacy in machine learning was given by Assistant Professor Reza Shokri, who is NUS Presidential Young Professor.


Reza introduced his research on data privacy and trustworthy machine learning

The second talk on tests and metrics to evaluate machine learning model explanations was given by Naresh Rajendra Shah, who is Co-founder and CTO at Untangle AI.


Naresh on how we could evaluate explanation for a machine learning model

We thank both speakers as well as OpenMined for what turned out to be a mind-opening experience for all the attendees.

Unclouding Hybrid Multi-Cloud

On 29 May 2019, we featured Michael Tsang as a speaker in our KDD.SG Seminar series, this time hosted at WeWork 71 Robinson. In his talk, Michael discussed  industry trends on  hybrid multi-cloud as well as its business implications and technology impact.  Here are several moments captured in photos.

Rise of Hybrid Multi-cloud, irrelevant buzzword or important trend?

May 29, 2019 | 6pm to 8.30pm | WeWork 71 Robinson


Cloud Computing has become a mainstay of IT industry in recent years. Many variations and flavors had since developed, and they can be quite confusing to those who are unfamiliar. Many chose to follow suit simply because it is a growing trend, but they may not be making the most appropriate decisions for their businesses if the intricacies aren’t studied thoroughly.

Cloud Computing in general can be viewed as a 3 layer architecture where, IaaS (infrastructure as a service) sits at the bottom, PaaS (platform aaS) in the middle, and SaaS (software aaS) on top.

Being the foundation layer, IaaS is critical in dictating an efficient and effective infrastructure that powers today’s businesses. In order to provision, deploy, and manage IaaS appropriately, specific terminology was developed to illustrate some of the most common deployment models, including private cloud, public cloud, hybrid cloud, and multi-cloud.

While public cloud, private cloud, and even hybrid cloud have been popularized, business needs continue to evolve and technology continue to advance. Today, Hybrid multi-cloud is becoming a growing trend in cloud computing. Deploying a cloud infrastructure that combines private on-premise data centers and multiple public cloud providers (hybrid multi-cloud) is daunting, but businesses continue to flock to this model. In his talk, Michael will discuss current industry trends and consumptions surrounding hybrid multi-cloud, implications of business and technology impact, and illustrate through a use case the need to embrace what is to come.


Michael Tsang currently serves as Senior Director of Channel Management APAC at Equinix, the leading data center provider in the world.

Prior to joining Equinix, Michael led engineering and research efforts at Hulu for 1 year, in areas such as recommendation, prediction, and pattern recognition.

Before Hulu, Michael spent 3.5 years with Alibaba, responsible for driving market entry and business growth in North and South America regions. He also led and completed Alibaba Cloud’s European data center strategy and owned Hong Kong’s partner management.

Prior to that Michael was with Microsoft for 16 years in various engineering roles including development and testing; gaining experience in operating systems, business rule engines, video rendering and transcoding, online advertising, and big data stream computing. Prior to Microsoft, he served at Hewlett-Packard in LaserJet and network management products.

Twin Speakers Amplify Neural Networks

On 25 April 2019, we were honored to feature two speakers in our KDD.SG Seminar series and host them in SMU School of Information Systems.


Agenda of the Seminar

Prof Jie Tang from Tsinghua University summarized several works on using deep learning for deriving graph representations, distilled their fundamental concepts, and described several generalizations and extensions on such models.


Jie describing the process of learning embeddings of nodes from a graph, in this case via employing Skip-gram technique on random walk paths on the graph


Jie discussing how NSGCN, a graph convolutional network with partial nodes’ features, would be much more efficient than ordinary GCN, yet obtaining close performance

In turn, Prof Michalis Vazirgiannis from Ecole Polytechnique described his recent work on using deep learning to derive representations for sets.


Michalis introducing a recent work on using neural networks to learn set representations


Michalis providing an overview of several related works on deep learning for graphs emerging from his lab

The audience was engaged, and the ensuing questions-and-answers were lively with a number of relevant questions. Overall, it was a very informative and inspiring session that certainly amplified our understanding of deep learning and neural networks.

Talk#1: Graph Neural Networks and Applications

Graph Neural networks (GNNs) and their variants have generalized deep learning methods into non-Euclidean graph data, bringing a substantial improvement on many graph mining tasks. In this talk, I will revisit graph convolutional networks and investigate how to improve their representation capacity. We discover that the performance of GNNs can be significantly improved with several simple and elegant refinements on the neighborhood aggregation and network sampling steps. Importantly, we show that some of the most expressive GNNs, e.g., the graph attention network, can be reformulated as a particular instance of our models. Extensive experiments on different types of graph benchmarks show that our proposed framework can significantly and consistently improve the graph classification accuracy when compared to state-of-the-art baselines.

Talk#2: Rep the Set: Neural Networks for Learning Set Representations

In several domains, data objects can be decomposed into sets of simpler objects. It is then natural to represent each object as the set of its components or parts. Many conventional machine learning algorithms are unable to process this kind of representations, since sets may vary in cardinality and elements lack a meaningful ordering. In this paper, we present a new neural network architecture, called RepSet, that can handle examples that are represented as sets of vectors. The proposed model computes the correspondences between an input set and some hidden sets by solving a series of network flow problems. This representation is then fed to a standard neural network architecture to produce the output. The architecture allows end-to-end gradient-based learning. We demonstrate RepSet on classification tasks, including text categorization, and graph classification, and we show that the proposed neural network achieves performance better or comparable to state-of-the-art algorithms
