Which of the following sentences is true about training and test datasets?
Answers
Answer:
Algorithms are used in machine learning to extract knowledge from datasets.
Explanation:
Step 1: The information underpinning the knowledge is retrieved from the data itself through machine learning-based algorithms. The data are investigated and evaluated in search of recurrent patterns or to find hidden causal links or linkages.
Step 2: One of the most widely used machine learning algorithms nowadays is the decision tree algorithm; it is a supervised learning method used to categorise situations. Both categorical and continuous dependent variables may be classified well with it.
Step 3: They learn from the knowledge provided to them and apply it to improve their performance in a particular activity. For instance, a computer system designed to locate cats in a photograph is initially trained on images of cats.
