Question 3

Which of the following statements are true about the differences between using convolutional neural networks (CNNs) in text tasks and image tasks?

A. When the CNN is used for text tasks, the kernel size must be the same as the number of word vector dimensions. This constraint, however, does not apply to image tasks. B. For CNN, there is no difference in handling text or image tasks. C. Color image input is multi-channel, whereas text input is single-channel. D. CNNs are suitable for image tasks, but they perform poorly in text tasks.

Question 6

When the chi-square test is used for feature selection, SelectKBest and _____ function or class must be imported from the sklearn.feature_selection module. (Enter the function interface name.) chi2 Explanation:
In feature selection for classification tasks, thechi-square (#²)statistical test can be applied to evaluate the independence between features and target labels.
In Python's scikit-learn library, this is implemented using:

Correct Answer:

python
CopyEdit
from sklearn.feature_selection import SelectKBest, chi2
SelectKBest selects the top K features based on scores returned by the chi2 function.
Exact Extract from HCIP-AI EI Developer V2.5:
"In scikit-learn, SelectKBest with chi2 can be used for feature selection by scoring features according to the chi-square statistic." Reference:HCIP-AI EI Developer V2.5 Official Study Guide - Chapter: Feature Selection Methods

Question 7

Which of the following statements about the functions of the encoder and decoder is true?

A. The output lengths of the encoder and decoder are the same. B. The decoder converts variable-length input sequences into fixed-length context vectors, encoding the information of the input sequences in the context vectors. C. The encoder converts variable-length input sequences into fixed-length context vectors, encoding the information of the input sequences in the context vectors. D. The encoder converts context vectors into variable-length output sequences.
