Question

While researching a topic, a student has taken the following notes:

The Million Song Dataset (MSD) includes main audio features and descriptive tags for popular songs.
Audio features include acoustic traits such as loudness and pitch intervals.
Many algorithms use these audio features to predict a new song’s popularity.
These algorithms may fail to accurately identify main audio features of a song with varying acoustic traits.
Algorithms based on descriptive tags that describe fixed traits such as genre are more reliable predictors of song popularity.
The student wants to explain a disadvantage of relying on audio features to predict a song’s popularity. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Choose 1 answer:
Choose 1 answer:
(Choice A) Algorithms based on audio features may misidentify the main features of a song with varying acoustic traits, making such algorithms less reliable predictors of popularity than those based on fixed traits.
A
Algorithms based on audio features may misidentify the main features of a song with varying acoustic traits, making such algorithms less reliable predictors of popularity than those based on fixed traits.
(Choice B) The MSD’s descriptive tags are reliable predictors of a song’s popularity, as the traits they describe are fixed.
B
The MSD’s descriptive tags are reliable predictors of a song’s popularity, as the traits they describe are fixed.
(Choice C) Audio features describe acoustic traits such as pitch intervals, which may vary within a song, whereas descriptive tags describe fixed traits such as genre, which are reliable predictors of popularity.
C
Audio features describe acoustic traits such as pitch intervals, which may vary within a song, whereas descriptive tags describe fixed traits such as genre, which are reliable predictors of popularity.
(Choice D) Many popularity-predicting algorithms are based on a song’s audio features, such as loudness and pitch intervals.
D
Many popularity-predicting algorithms are based on a song’s audio features, such as loudness and pitch intervals.

[AI-generated answer — Bot GPT 3.5]

(Choice A) Algorithms based on audio features may misidentify the main features of a song with varying acoustic traits, making such algorithms less reliable predictors of popularity than those based on fixed traits.

This choice effectively uses information from the notes to explain the disadvantage of relying on audio features to predict a song's popularity. It highlights the potential for misidentification of main features in songs with varying acoustic traits, which can make algorithms based on audio features less reliable compared to those based on fixed traits like genre.
