Features can come in many types
(numbers, categories, text etc.)
Common real life examples take 100s
to 1000s of features!
Each dataset has
only one Label

The basics
of AI

Example: Use AI to Guess a Person’s Mood
Training: Use text data
describing feelings for happy or

Examples of
happy and sad

Training: Use text data
describing feelings for happy or
sad. Develop a model.
Examples of

Question ‘sentence’ This is called a feature
Answers ‘feeling’ This is called a label

AI Basics
Training : Use data to develop a ML model.
Model : A formula learned from the data
that can be used to predict new outcomes.
Inference/Prediction : Using the model
to answer new questions.

Training : Use data on feelings for happy or
sad. Develop a model
Model : Learn how to map feelings to
“Happy” or “Sad”
Inference/Prediction : Provide a new
feeling “example – I am feeling great!”.
Predict that this is “Happy”

What is an AI Service?
• An AI Service is a program that
takes questions (new data) and
uses a model to create answers
(predictions)

What is an AI Service?
• An AI Service is a program that
takes questions (new data) and
uses a model to create answers
(predictions)
• An AI service connects with your
application
• Application sends questions
• AI service sends back
predictions/answers
Application uses the answers
