Which of the following is a regression task? (multiple options may be correct)<\/p>\n\n\n\n

(a) Predicting the monthly sales of a cloth store in rupees.<\/p>\n\n\n\n

(b) Predicting if a user would like to listen to a newly released song or not based on historicaldata.<\/p>\n\n\n\n

(c) Predicting the confirmation probability (in fraction) of your train ticket whose currentstatus is waiting list based on historical data.<\/p>\n\n\n\n

(d) Predicting if a patient has diabetes or not based on historical medical records<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct options for regression tasks are:<\/p>\n\n\n\n

(a) Predicting the monthly sales of a cloth store in rupees.<\/strong>
(c) Predicting the confirmation probability (in fraction) of your train ticket whose current status is waiting list based on historical data.<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Regression tasks<\/strong> involve predicting a continuous value. In other words, the output variable (target variable) is a real number, often representing quantities or probabilities.<\/p>\n\n\n\n

    \n
  • Option (a) Predicting the monthly sales of a cloth store in rupees:<\/strong> This is a regression task because the sales amount is a continuous value (measured in rupees). The task involves predicting a real-valued number based on historical data, such as previous sales, seasonality, or marketing efforts. Sales data is inherently continuous, so this task is a classic example of a regression problem.<\/li>\n\n\n\n
  • Option (c) Predicting the confirmation probability (in fraction) of your train ticket whose current status is waiting list based on historical data:<\/strong> This is also a regression task. The output here is a probability, which is a continuous value between 0 and 1, representing the likelihood that the waiting-list ticket will get confirmed. Probabilities are continuous values and are typically predicted using regression models, especially when dealing with historical data.<\/li>\n<\/ul>\n\n\n\n

    Why the other options are not regression tasks:<\/h3>\n\n\n\n
      \n
    • Option (b) Predicting if a user would like to listen to a newly released song or not based on historical data:<\/strong> This is a classification task<\/strong>, not regression. The output is categorical, either “Yes” or “No,” meaning it’s a binary classification problem, where the goal is to classify the user\u2019s preference, not predict a continuous value.<\/li>\n\n\n\n
    • Option (d) Predicting if a patient has diabetes or not based on historical medical records:<\/strong> This is also a classification task<\/strong>. The output is categorical, with two classes\u2014diabetic or not\u2014so it involves assigning the patient to one of these two categories, not predicting a continuous value.<\/li>\n<\/ul>\n\n\n\n

      In summary, regression tasks predict continuous values, whereas classification tasks predict discrete categories. Therefore, (a) and (c) are regression tasks, while (b) and (d) are classification tasks.<\/p>\n","protected":false},"excerpt":{"rendered":"
