Introduction to Machine Learning

What is Machine Learning?

• A method for computers to recognize patterns and make decisions without being explicitly programmed

• A way to manually program computers to perform tasks

• A type of hardware used in computers

• A programming language

What are features in the context of machine learning?

• The outputs a model predicts

• The inputs that a model uses to make decisions

• The errors a model makes

• The hardware components of a computer

What is a label in machine learning?

• The name of a dataset

• The output you are trying to decide or predict with a model

• The process of training a model

• The input data for a model

What is a model in machine learning?

• A physical representation of data

• A computer program designed to make a decision

• A type of data storage

• A mathematical equation

What is supervised learning?

• When a model learns without any examples

• When a human trains a model to learn with examples

• When a model is used to supervise other models

• When a model is used to predict numerical data

What is unsupervised learning?

• Finding patterns in data that doesn't have any labels

• Training a model with labeled data

• Using a model to predict future events

• A type of supervised learning

What is categorical data?

• Data that can be counted or measured

• Data that can be separated into groups

• Data that is always numerical

• Data that is always continuous

What is classification in machine learning?

• Predicting a numerical value based on other features

• Predicting a category based on other features

• Sorting data in ascending order

• Calculating the mean of a dataset

What is bias in the context of machine learning?

• When a decision is completely random

• When a decision favors some things and de-prioritizes or excludes others

• When a model is perfectly accurate

• When a model has no errors

What are ethics in the context of machine learning?

• Guidelines for good behavior

• The process of training a model

• The mathematical equations used in models

• The hardware used to run models
