Research and Systems:

With the ubiquity of Big Data and fusion of applications and technologies, the projects are related in many aspects. Beng Chin approaches research problems and system design with the philosophy that all algorithms and structures should be simple, elegant and yet efficient so that they are implementable, maintainable and scalable in actual applications, and all systems must be efficient, scalable, extensible and easy to use. Beng Chin's ongoing/recent large system projects include:

  1. Hyperledger++(2015-): He works on benchmarking, and performance issues of blockchain systems, in particular, on consensus model, execution engine and storage engine. His group designed a comprehensive blockchain benchmarking framework and open source called BLOCKBENCH. Hyperledger++ is the blockchain backend of MediLOT, a healthcare blockchain system, which is patient centric and supports decentralized, personalized medicine and healthcare data analytics.
  2. ForkBase and ForkCloud (2015-): ForkBase is an efficient tamper-proof data storage system designed to provide efficient support and fast development of forking-enabled applications, such as "GIT-for-Data", tamper-evident Blockchain, collaborative analytics and OLTP with versioning. ForkBase is deployed as the storage engine of Hyperledger++. ForkCloud is a GIT-for-Data system that encapsulates data cleansing, crowdsourcing, ML design and testing, and versioning to facilitate AI development on sensitive data.
  3. SINGA(2014-): a distributed Deep Learning platform (indirectly funded by an ASTAR grant and NRF CRP). Apache SINGA is an Apache Incubator open source, distributed training platform for deep learning amd machine learning models, and is designed based on four principles, namely, usability, scalability, extensibility and elasticity. Apache SINGA v2.0.0 has AutoML features, a Healthcare model zoo which contains deep learning models that have been used for healthcare research, and facility for porting other models onto SINGA. In 2016, he highlighted the challenges and opportunities of exploiting AI/ML on improving database system usabability and performance in SIGMOD Record 2016.
  4. GEMINI (2011-): GEMINI is a healthcare AI stack. He works closely with a number of hospitals, understands their needs, and builds an end-to-end data processing and analytics stack. GEMINI end-to-end stack supports data cleansing (DICE), crowdsourcing (CDAS), ML-based predictive analytics (SINGA), cohort analysis (CohAna), and data versioning and management (ForkBase). He works with five hospitals on prediabetes prevention (eg. JurongHealth), and NUH and SGH on various disease specific predictive analytics (eg. DPM, AKI, readmission modelling).
  5. CIIDAA(2012-2018): a Comprehensive IT Infrastructure for Data-intensive Applications and Analysis is an CRP project funded by NRF (NRF-CRP8-2011-08) from 2013-2017. The main objective is to use cloud computing to address the Big Data problem. For specific applications, this approach has been shown to be effective, and systems such as Hadoop have become very popular. However, they have limitations (see ACM Computing survey paper on MapReduce based systems and IEEE TKDE Survey on in-memory systems), and are suitable only for a class of applications that have a structure amenable to fine-grain asynchronous parallelization. Furthermore, there remain many challenges in actually using cloud computing systems in practice, including issues of resource contention across multiple jobs being run concurrently. The aim of this project is to develop a platform for supporting real-time data integration and predictive real-time analytics in the area of web consumers (collaborating with Starhub) and healthcare (collaborating with NUH, National University Health System).
  6. epiC(2009-2013): an Elastic, Power-aware, data-Intensive Cloud platform, funded by an MOE grant (2010-2012). The objectives are to design and implement an efficient multi-tenancy cloud system for supporting high throughout low latency transactions and high performance reliable query processing, with online and interactive analytics capability. memepiC (2014-) is an extension of epiC project focusing on exploiting hardware features, multi-cores and large memory. Related earlier project: UTab.
  7. LogBase(2012-2016): a distributed log-structured data management system, funded by ASTAR (2013-2016). LogBase adopts log-only storage to handle high append and write load, such as Urban/Sensor information processing. Indexing, transaction management and query processing are the key issues that have been investigated and source codes have released. LogBase is related to an ongoing research on database support for Energy and Environmental Sustainability Solutions for Megacities.
  8. CDAS(2011-2015): a Crowdsourcing Data Analytics System that has been designed to improve the quality of query results and effectively reduce the processing cost at the same time. It is being built as a crowdsourcing system that provides primitive operators to facilitate composition of crowdsourcing tasks. Other key issues such as privacy and applicability, and various applications are being investigated.
