2、What do you call the commonly used AI technology for learning input (A) to output (B) mappings?1 分

A、Unsupervised learning

B、Artificial General Intelligence

C、Reinforcement learning

D、Supervised learning  

3、

You want to use supervised learning to build a speech recognition system. The figure above suggests that in order for a neural network (deep learning) to achieve the best performance, you would ideally use: (Select all that apply)1 分

A、A large dataset (of audio files and the corresponding text transcript)

B、A small dataset (of audio files and the corresponding text transcript)

C、A large neural network

D、A small neural network

 

4、The only way to acquire data for a supervised learning algorithm is to manually label it. I.e., given the input A, to ask a human to provide B.1 分

A、True

B、False

5、Which of these statements regarding data acquisition do you agree with?1 分

A、It doesn’t help to give data to an AI team, because they can always produce whatever they need by themselves.

B、Some types of data are more valuable than others; working with an AI team can help you figure out what data to acquire.

C、Only structured data is valuable; AI cannot process unstructured data.

D、It doesn’t matter how data is acquired. The more data, the better.

 

6、You run a company that manufactures scooters. Which of the following are examples of unstructured data? (Select all that apply.)1 分

A、Insights into how to market cat food more effectively, depending on the breed of cat.

B、A slide deck presenting a plan on how to modify pricing in order to improve sales.

C、A neural network that closely mimics how cats’ brains work.

D、A large dataset of images labeled as “Cat” and “Not Cat”

 

8、Based on the terminology defined in Video 4, which of the following statements do you agree with? (Select all that apply.)1 分

A、Deep learning is a type of machine learning.  (I.e., all deep learning algorithms are machine learning algorithms.)

B、Invest in unified data warehouses

C、Spot automation opportunities

D、All of the above

 

10、Say you want to input a picture of a person’s face (A), and output whether or not they are smiling (B). Because this is a task that most humans can do in less than 1 second, supervised learning can probably learn this A-to-B mapping.1 分

A、True

B、False
