Using Machine Learning Techniques to Identify Top Stocks

April 1st 2019 | 6.00pm to 8.00pm | ING Bank, Spark #12; 1 Wallich Street, Guoco Tower, 078881

Abstract

Interested in what goes into building an automated stock investment system? Using machine learning techniques of both unsupervised and supervised varieties, one can mine troves of data to discover statistical patterns towards identifying top stocks to trade. Demonstrated on a case study, we will see how the learned models perform upon paper trading, comparing the stock portfolio performance to that of the stock market index.

What Should A Data Scientist Know?

That’s the question that a group of data scientists from industry and academia discussed over dinner on 14 December 2018 at the NUSS Suntec City Guild House.  We were fortunate to have Marianne Winslett, a professor emerita of computer science at the University of Illinois at Urbana–Champaign, to open the event with a keynote address. We see the role of SIGKDD as contributing to identifying and building the skills required for data science professionals.  Though simple and direct answers to such a complex question are elusive, the discussions were fruitful and pointed us in the right direction. It was also a chance for us to reflect and regroup as a community.

Marianne Winslett (UIUC) gave her take on the question, including the need for standards to ensure that professionals could build something that’d work, the need for a realistic mindset aware of the limitations of statistics, as well as the attention to ethical issues

In between dinner courses, we had breakout discussions on the topic, moderated by Giuseppe Manai (Chapter Secretary)

Though it was not by deliberate design, one table had primarily industry professionals, which brought forth issues on how to hire and select the right data scientists

The other table just happened to have many academicians, with discussions touching on the skills and competencies of data scientists

Hady Lauw (Chapter Chair) closed the event, summarizing the noted points for future follow-ups.

Networking over Networks

On 18 Sep, we had a chance to learn about the power of networks from Dr. Gábor Benedek (Lynx Analytics), while networking with data science enthusiasts over pizza and beer. We are also grateful to WeWork for hosting our event.  Here are a few pictures to remember by.

In addition to graph theory and techniques, Gábor covered several case studies relating to social and health sciences as well

Big Graph Data Intelligence – Analyzing Large Connected Data in Social and Health Science

September 18, 2018 | 6pm to 8.30pm | WeWork 71 Robinson

Abstract

The miracle behind Social Data is that we have information on the detailed structure of how people are connected to each other, who are the family members, who are the friends, and who are the influencers, who are the followers. We call this structure as graph topology. But beside the Social Data Topology (from diverse sources) we can also observe characteristics of and behavior mechanism among the individuals. Many researches have proved that inside micro-topologies (cliques or communities) people tend to think, decide, purchase or do similar things, have similar profiles in many cases. Thus, if we want to understand or change customers’ decision, we must use the micro-topology information, not just individual connections.

Today, multinational companies (banks, airlines, telecoms, insurance companies and many other domains) are closer than ever to analyze, understand and utilize Social Data. They usually have at least three different sources of Social Data, which is sufficient to build their own transactional Social Network. First, A-to-B transactions (calls, instant messages, money transfers, bookings). Second, (co-)locations and the (co-)movements (same address, sharing bills, traveling together). Third, digital behavior (browsing history, app usage) of customers, potentially complemented with external information. Just like Facebook helps not only to derive the Network, but add much diverse information on attributes and interests. This in turn enables further deep dive on the homogeneity of these communities, verify those cases when the network is similar in demography, when the network is giving an insight on commercial decisions, when the network enables the spread of word of mouth.

However, creating the transactional Network using these attributes is not easy, especially when there are dozens of millions of customers, and billions of possible and measurable interactions of and between them. The different sources of information can contain contradictions and confusions, when we observe that overlaid topologies are not matching. (E.g.: online friends and offline friends.) Lynx Analytics has experiences and solutions to build and use these networks efficiently.

1st Singapore ACM SIGKDD Symposium

On Friday afternoon 27 July 2018, a number of esteemed data science thought leaders gathered at Hotel Jen Orchardgateway in the first-ever, invitation-only Singapore ACM SIGKDD Symposium.

It was an insightful session, and the attendees got to know one another, shared their current focus, exchanged ideas, and began a discussion towards a common vision.  We were very fortunate to have a diverse representation from academia, government, and industry.  There is also a consensus to pursue further such activities in the future that forge a stronger connection among the data science community in Singapore.

Look out for coming events in this space!
