Data Science

What Data Science do not do

• Built and validate the models

• Deploy the performance

• Emerge low complexity of analysis

• Collect and explore the data

(1) Frame the problem

(2) Perform Depth analysis

(3) Process the data

(4) Collect the raw data

(5) Communicate the result

(6) Explore the data

What is the correct sequence of Data Science Stages

• 1 - 2 - 3 - 4 - 5 - 6

• 1 - 4 - 3 - 2 - 6 - 5

• 1 - 4 - 3 - 6 - 2 - 5

• 1 - 6 - 3 - 4 - 2 - 5

When we apply Math & Science into domain Business knowledge, what do you get

• Machine Learning

• Software Development

• Traditional Research

• Data Science

Three correct types of Machine Learning are ?

• Supervised Learning (Data Driven) ; Unsupervised Learning (Task Driven) ; Reinforcement Learning (Learn from Errors)

• Supervised Learning (Error Driven) ; Unsupervised Learning (Task Driven) ; Reinforcement Learning (Data Driven)

• Supervised Learning (Task Driven) ; Unsupervised Learning (Error Driven) ; Reinforcement Learning (Data Driven)

• Supervised Learning (Task Driven) ; Unsupervised Learning (Data Driven) ; Reinforcement Learning (Learn from Errors)

Supervised Learning is/do ,,,,, EXCEPT

• Make future prediction

• Require labeled data

• Relies much more on human interpretation

• Show us how variables affect each other

Type of machine learning that has zero predictive power ?

• Supervised Learning

• Unsupervised Learning

• Reinforcement Learning

• None of them

If we want to show relationship between people learn online and linguistic skill, what is the best graph to visualize ?

• Cumulative Histogram

• Bar Chart

• Mosaic display

• Scatter plot
