|
|
Predicting the temperature (in Celsius) of a room from other environmental features (such as atmospheric pressure, humidity etc)
|
|
|
Finding the shorter route between two existing routes between two points
|
|
|
Predicting if a particular route between two points has trac jam or not based on the travel time of vehicles
|
|
|
None of the above

Detailed explanation-1: -Similarly, Option 4 predicting if the route would have traffic or not, would observe the time of travel and may be past records, so it is a classification problem.
Detailed explanation-2: -The answer to the question is option a, ” Predicting whether it will rain or not on a particular day". It is not a classification task because, here the machine is making predictions instead of classifying into categories.
Detailed explanation-3: -Answer: 1. Predicting the temperature (in Celsius) of a room from other environmental features (such as atmospheric pressure, humidity etc).
Detailed explanation-4: -A classification problem in machine learning is one in which a class label is anticipated for a specific example of input data. Problems with categorization include the following: Give an example and indicate whether it is spam or not. Identify a handwritten character as one of the recognized characters.
Detailed explanation-5: -Machine learning (ML) classification problems are those which require the given data set to be classified in two or more categories. For example, whether a person is suffering from a disease X (answer in Yes or No) can be termed as a classification problem.
