Motivation• “We have to do our own research” – effective
health care is ethnic, cultural and environmental dependent
• NUS has core technology

6
• Learning depends on data, and data is ethnic, cultural and environmental dependent
• Leverage on NUS strength in knowledge learning and discovery
8
Data and Cyber Security
• Medical Record• confidentiality• data integrity• holistic and timely
• Provide a secure and trusted environment for safe housekeeping of patients’ data – prevent hacking and malicious software
10
Nature of Data• Unstructured• in natural language• knowledge structuring for meaningful exploitation
• non-textual• visualization
12
• uncertain & inconsistent
• doctors, nurses, care givers, patients may give conflicting data or interpretation of data over the years due to changes in context (eg. situation changes, knowledge enhances)
• Need to do analytics to form a logical picture out of these unstructured, inconsistent data
13
• Need clever means of structuring knowledge and reasoning from uncertain/inconsistent data• thru natural language processing• thru crowd sourcing
• make the unstructured and uncertain/inconsistent data exploitable
15
• Predictive Analytics (Clinical)• hospital bed• prediction to reduce re-admission• medical, social conditions
• prediction of which patient needs more urgent attention (eg. ICU, Emergency Deparment)
Predictive Analytics
16
• Predictive Analytics (Resources)• ambulance• prediction and optimization of ambulance
placement• stream data from ambulance to hospital for
timely action upon arrival at hospital
17
• Predictive Analytics (Wellness)
• wellness/mobile device
• behavioral
• drug and supplements
• food
18
• Diagnosis and treatment• prognosis prediction• develop hypotheses• eg. for uncommon diseases
• develop better diagnostic plan• also reduce unnecessary dosage (imaging and
drugs)• knowledge management
Prescriptive Analytics
20
• Food Safety• Pesticide Screening• mass screening of peticide using advanced imaging
• Genetically modified food• Organic food• develop technology to certify organic food
• Meat safety
22
• Wellness: Sensors & Devices• Mobile Phones as sensing device
• Other wearable gadgets• transmitting health data including
vital signs
• Predictive and Prescriptive Analytics
23
• Wellness: Music • Music Enhanced Preventive Exercise• Music Therapy
• Wellness: Evidence-based design computing & human-centered computing
24
Pioneering a Computational Healthcare Industry• Inspired by our success in water technology
• Pioneer a computational healthcare industry, put Singapore on global map of health care with Asian context
25
Implementation Plan
• Medical is about Human
• Need to build confidence before adoption• practice on archival data• training of doctors• do a pilot study
• Leverage on crowd sourcing for general public health
