• Deep Belief Network (DBN)

Which machine learning technique is best suited for identifying unusual patterns or outliers in a dataset?

• Regression

• Clustering

• Classification

• Dimensionality reduction

Which algorithm is commonly used for unsupervised learning?

• Decision Trees

• K-Nearest Neighbors

• Random Forest

You are part of a data science team that is working for a national real estate company. You create a report that shows a relationship between the square footage of houses and their sale prices. Specifically, the report demonstrates that as the square footage of a house increases, the sale price tends to increase as well. What is the most likely diagram that your team created?

• Multiclass classification diagram

• Linear regression and scatter plots

• Pivot table

• K-means cluster diagram

Your university wants to use machine learning algorithms to help sort through incoming student applications. An administrator asks if the admissions decisions might be biased against any particular group, such as women. What would be the best answer?

• Machine learning algorithms are based on math and statistics, and so by definition will be unbiased.

• There is no way to identify bias in the data.

• Machine learning algorithms are powerful enough to eliminate bias from the data.

• All human-created data is biased, and data scientists need to account for that.

You want to create a supervised machine learning system that identifies pictures of kittens on social media. To do this, you have collected more than 100,000 images of kittens. What is this collection of images called?

• training data

• linear regression

• big data

• test data

Self-organizing maps are specialized neural network for which type of machine learning?

• Semi-supervised learning

• Supervised learning

• Reinforcement learning

• Unsupervised learning

With traditional programming, the programmer typically inputs commands. With machine learning, the programmer inputs

• commands

• data

• programs

• algorithms

The famous data scientist Andrew Ng has been quoted as saying, "Applied machine learning is basically feature engineering." What is feature engineering?

• Scraping new features from web data

• Creating new variables by combining and modifying the original variables

• Deleting original variables by combining and modifying the new variables

• Using deep learning to find features in the data
