High Performance Analytics (HPA)

  • Meeting Challenges
  • The What?
  • Understanding the Analytic paradigm Shift
  • High Performance Analytics – the SAS way
  • What is the business value add

What is HPA delivering

What is HPA about?

  • Evolving business needs

Why does business need it?

  • Leveraging information to compete in the market
  • Raise revenue/ profits
  • Reduce costs and inefficiencies
high performance analytics grew from the need for big data analytics

Data measurement is the modern equivalent of the microscope*

At the World Economic Forum last month in Davos, Switzerland, Big Data was a marquee topic. A report by the forum, “Big Data, Big Impact,” declared data a new class of economic asset, like currency or gold.

28 year Asst. professor at Stanford combined math with political science in his undergraduate and graduate studies, seeing “an opportunity because the discipline is becoming increasingly data-intensive.” His research involves the computer-automated analysis of blog postings, Congressional speeches and press releases, and news articles, looking for insights into how political ideas spread.

It’s not just more streams of data, but entirely new ones- countless digital sensors worldwide in industrial equipment, automobiles, electrical meters and shipping crates- measure and communicate location, movement, vibration, temperature, humidity, even chemical changes in the air..

* Quote from Professor Brynjolfsson

The Age of Big Data, By STEVE LOHR, NYT

The new Normal – what is HPA doing to Analytics?

Analyze 100% of data

More/New variables

More model iterations

Manage complex models

More models (per domain area)

More questions/ideas/scenarios to evaluate

Multiple deployment options: batch, real-time

Continuously monitor model effectiveness and retrain

The Things you can Think!

HPA combines the three pillars to deliver results

Data: Leveraging technology to collect, access and manage data

Analytics: Adapting to new technology, In-memory, Grid, In-database

Platform: Positioning analytics within industry leaders technology solutions

High Performance Analytics

advanced analytics and fast computing capabilities are brought together with SAS HPA

In a recent National Postinterview with Jim Goodnight, the SAS CEO explains it like this:

There's a lot of business processes that will be changing because of the speed at which we can do analytics; using a thousand processes in parallel to do these computations can make it possible to do huge problems that we would never have been able to do before because it would take too long on a single processor.

A big part of how HPA gets its speed: it breaks larger problems down into smaller pieces.

From Sampling to Populations analysis

50 Attributes to 500+ Attributes

Reduce run times 18 Hrs - 30 minutes

Build more complex models

3 month Lagged modeling to Real time updates

Structured data to combining unstructured data

Shortening model lifecycle

More frequent updates, model iterations

  • 70% of the effort in analytics is typically on the information management side of the model.
  • Analytical teams in the middle are small but crucial for translating the data assets into actionable insights.
  • The organization change side highlights the attributes of behavior changes needed by business users.

Key differentiators

Only in-memory offering in the market delivering high-end analytics, including text mining and optimization

Addresses the entire model development and deployment lifecycle

36 years of proven technology...faster. Opens up vast array of possibilities to get value from big data

Top five ways high-performance analytics will transform marketing

Faster, more sophisticated, effective segmentation

  • segmentation tests can be run against the entire populations in order to determine the best campaign interaction methods

Real-time, relevant next-best customer actions or offers

  • This results in a more relevant offer or customer interaction surfacing at the “point of need” in real-time

Instant deployment and management of marketing models that give you a sustainable advantage

  • companies to quickly and efficiently update their numerous models without submitting a slow overnight batch update process.

1:1 real-time experiences to bolster brand connections

  • The outcome is more precise, real-time interactions with consumers at the “point of need.”

Optimized marketing for broader business impact

  • Now businesses can not only determine the customer and financial impacts of their campaigns faster but also adapt instantaneously to market, competitive and customer changes.

Reduce model processing time from four hours to 10 seconds.

Reduce misclassification rates from 30% to 10%

Historical models improved with more than 10% lift

I can now tell that a prescription will harm a patient before you write it…

I can tell that a customer is dissatisfied before you lose him or her...

I can now determine that a claim is fraudulent before you pay it…

“ SAS is helping make our member services the best in the industry, In less than one hour, we can load a huge table (169 million row dataset), find the best variables, compare different models and pick the best model. I would not attempt to model a dataset this large without SAS HPA Server.”
