- Is this movie a comedy, a documentary, or a thriller
- Will it be a Rainy day or Sunny Day tomorrow
- Will Indian Cricket team win the next World Cup
- Should we gift a book or a gift card
Answer – Option (A) Is this movie a comedy, a documentary, or a thriller
For the question “Which of the following are multi class classification problem” option (A) “Is this movie a comedy, a documentary, or a thriller” is the correct choice. This is because, in multi class classification, you need a situation where there are more than three distinct possible classes or categories.
In option (A) you have to find that in which genre the movie falls into and you have been given these choices “comedy”, “documentary”, and “thriller”. As you can see there are three possible outcomes for the following scenario, and thus by the definition you can easily say that it is a “multi class classification”.
To better understand the answer let’s look at the other three options in the given question.
Option (B)
“Will it be a Rainy day or Sunny Day tomorrow?” In this situation, you are able to find only two possible outcomes and that is whether the next day will be a rainy day or a sunny day. Hence, when there are only two possible classes then it is referred to as a “binary classification problem”. Therefore, this is not the correct answer.
Option (C)
“Will Indian Cricket team win the next World Cup”. In this scenario, we are trying to predict whether the Indian Cricket Team will be able to win their next World Cup or not. Here also, the only possible results are either a win or a loss. Since there are only two possible categories which mean it is also a “binary classification problem”, the same as option (B).
Option (D)
“Should we gift a book or a gift card”. In this case, you have to decide whether you should either gift a book or a gift card therefore, there are only two possible results and they differ. Therefore, this option as well falls under the same as the other two options which is a “binary classification problem”.
Summary
In short, by looking at the choices given in the question you can clearly see that only option (A) fulfills the requirements of a “multi class classification” by having three distinct classes or categories (comedy, documentary, thriller). The other three options do not meet the requirements and fall into the “binary classification problem” by having only two distinct classes or categories.
