What is Big Data?

CS535 Big Data | Computer Science Department | Colorado State University

Big Data• Things one can do at a large scale that cannot be done at a smaller one

• To extract new insights• Create new forms of values

• Big Data is about analytics of huge quantities of data in order to infer probabilities• Big Data is NOT about trying to “teach” a computer to “think” like humans

• Providing a quantitative dimension it never had before


The three(or four) Vs in Big Data• Volume

• Voluminous• It does not have to be certain number of petabytes or quantity.

• Velocity• How fast the data is coming in?• How fast you need to be able to analyze and utilize it

• Variety • Number of sources or incoming vectors

• Veracity• Can you trust the data itself, source of the data, or the process?• User entry errors, redundancy, corruption of the values• Data cleaning


Who is using Big Data?

Connected cars• Single hybrid plug-in car generates up to 25 gigabytes per hour

• Connected cars• $130 billion • Traffic problem, re-routing based on the volume of traffic• Alerts driver when a road conditions are hazardous by automatically activating anti-lock break

• This information is shared by the vehicles that are nearby


The Artemis project: Saving “preemies” using Big Data• The Artemis project

• Dr. Carolyn McGregor

• Toronto’s Hospital for Sick Children, University of Ontario Institute of Technology and IBM• Captures and process the patients’ data in real time

• 16 different data streams

• Heart rate, respiration rate, temperature, blood pressure and blood oxygen level• Around 1,260 data points per second

• System detects subtle changes that may signal the onset of infection 24 hours before overt symptoms appear




Look Who’s Peeking at Your Paycheck• Experian’s Income Insight

• Estimates people’s income level• Based on their credit history • Trains the estimation model using selected credit history and tax information from IRS

Related research areas• Storage systems

• How can we efficiently resolve queries on massive amounts of input data?• The input dataset may be presented in the form of a distributed data stream

• Machine learning• How can we efficiently solve large-scale machine learning problems?• The input data may be massive; stored in a distributed cluster of machines

• Distributed computing• How can we efficiently solve large-scale optimization problems in distributed computing environments?• For example, how can we efficiently solve large-scale combinatorial problems, e.g. processing of large

scale graphs?
