4. AGENDA
• What is AI and analytics
• Natural language Query
• Simple prediction algorithm in existing visuals
• The ML model
• AI builder and image recognition
• Summary

6. Algorithms
Artificial Intelligence
Machine Learning
Human Input & Interpretation is Always Required
What is Predictive Analytics?

7. WHAT IS AN ALGORITHM?
An algorithm is a set of rules to be followed in
problem solving operations
Initial Input Computation
Instructions
Produce
Output

8. SORTING ALGORITHM EXAMPLE
Sorting algorithm takes an unsorted list, applies pre-
determined instructions and produces a sorted list
Unsorted
List
Sorting
Instructions
Sorted List

9. WHAT IS ARTIFICIAL
INTELLIGENCE?
Artificial Intelligence is “intelligence”
demonstrated by machines and is often
associated with cognitive function

10. WHAT IS ARTIFICIAL INTELLIGENCE?
Artificial Intelligence is “intelligence”
demonstrated by machines

11. TYPES OF ARTIFICIAL INTELLIGENCE
Artificial intelligence
applied to a specific task
Applied
AI
General
AI
Ability to accomplish a
variety of cognitive tasks

12. DIFFERENT TYPES OF ANALYTICS
• AI is in the Predictive
analytics space, we
are predicting based
on the past the
future observations

13. WHAT IS MACHINE LEARNING?
Machine Learning is an application of Artificial
Intelligence that learns to construct Algorithms
from experience

16. LET’S GO TO POWERBI
• Quick Insights

17. THE FIRST STEP – EXPLORING AND VISUALIZING YOUR DATA –
QUICK INSIGHTS
Quick insights mode
Quick insights mode

18. ADDING INFORMATION TO OUR DATA
VISUALIZATION
PowerBI
Min value line
Max value line
Trend line – we can see that the AVG delay time
increases?
Expediential Smooth
Seasonality – 7 points (week in a month)
Ignore last 10 points – to check our prediction
Forecast length- to see what the other 7 days will
look like

19. STATISTICS…(YES WE KINDA HAVE TO)
WHICH PREDICTION MODEL ARE WE USING?
Average
Single Exponential Smoothing
Exponential smoothing is a rule of thumb
technique for smoothing time series data using
the exponentialwindow function. Whereas in the
simple moving average the past observations
weighted equally,exponential functions are used
to assignexponentially decreasing weights over
time.
( Wikipedia to the rescue… )
Moving Average
The last month might be a better prediction for
flights than the last 20 months
Weighted Moving Average
Some observations are more significant than
others, flights of a domastic flight company have
different performance and cannot be compared to
others or big vs small planes
Can be chosen, for the single smoothing, between 0.1
and 0.9, is chosen through a local optimal minimum
value
We choose the best value for α so the value which
results in the smallest MSE. (Mean of Square Errors)

20. ADDING INFORMATION TO OUR DATA
VISUALIZATION
PowerBI – How can we explain the predicted results?
Trend line – we can see that the AVG delay time
increases?
Possible explanations for this prediction and what can we do about it – Prescriptive Analytics
• End of October - Thanksgiving?
• Weather changes at the airports for the worse
• The trend line doesn’t continue for the predicted data
• How can we control the Alpha? Well in Power View for O365, not in PowerBI yet

21. POWERBI AI

22. IN AZURE ML

23. POWER PLATFORM

24. THE AI BUILDER - POWERAPPS
PowerBI is no longer a “single in the mingle” it has a family – the power platform
So How do we do AI with the PowerPlatform?
Meet the AI builder

25. THE AI BUILDER HOW TO BUILD YOUR ON AI?
Create the
terms in CDM
Create new
model
Select type -
image
Add picturesAdd TagsTrain
Save Test
Add to an
application

26. CDM COMMON DATA MODEL – ADDING
ENTITIES TO TAG

27. WHY DOES AN AI MODEL NEEDS TO TRAIN?
Search results of my
pictures in google
for the word:
“BIRD”

28. THE GOOSE DETECTOR

29. TEST - WHAT IS THE PREDICTION
ACCURACY?

30. SHARING YOUR
APPLICATION –
SHARE THE BIRD

31. AND THE RESULT?
With Ken’s help, 1 Goose was successfully
detected in the picture!

32. BUT WAIT…GOOGLE CAN DETECT MY MOM IN
EVERY PICTURE SO WHAT’S SO EXCITING
ABOUT THIS GOOSE CHASE?
• You can add the AI feature right into your own
application
• Building inspection object detection in the
application
• Business Data and Business Pictures
• One Drive for Business or Azure repository and files
management
• CDM – the tagging is an object in your Common
Data Model not stand alone object
