The Webinar
named “The Age of Analytics: Data Driven Insights in the Services Industry” was
organized by Minitab on 3rd Jun 2020. In the beginning, Ms. Iza Ng
(Business Development Manager, TechMax) introduced today’s speaker Dr. Scott
Kowalski.
Dr.
Scott Kowalski (Advisory Technical Training Specialist, Minitab) was key
speaker today and he is major in Statistics.
He said 87% of global businesses though data is the key to new business
growth, delivering better results for customer, and the foundation for making
important business decisions.
He
briefed the Data Driven Insights from operational environment to data to
information and then to intelligence.
Data alone is not intelligence. It needed to be employed for modeling
and enable people made smart decision.
Then
Dr. Scott Kowalski briefed what is Data Analytics that included four stages. They
are Descriptive, Diagnostic, Predictive and Prescriptive Analytics.
After
that Dr. Scott shared Healthcare research employed Predictive Analytics using
Minitab. He would like to reduce the number of resident falls and collected a
series of data sets.
Simply,
Pareto Chart was employed and found that the high frequency of resident falls
on 4:00am and 2:00am.
And
then he introduced data about Service that data-driven decision could reduce
cost and enhance efficiency, as well as, quality of business.
Dr. Scott
used predictive equation (based on regression) for Banking Example.
Finally,
Dr. Scott briefed the Machine Learning that separated into Unsupervised Learning
(Clustering) and Supervised Learning (Classification & Regression).
The
key of Machine Learning is used 70% of data as training set and 30% of data as
test set. If 100% of data use for
training set that model will be over-fit.
Lastly,
Tree-based machine learning new menu was introduced for predictive analytics
(e.g. CART® Classification; CART® Regression).
At
the end, Ms. Iza Ng invited us to join the coming Webinar Wednesday for Machine
