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.
