Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Identify the correct statement(s) in context of machine learning approaches:Statement I:In supervised approaches, the target that the model is predicting is unknown or unavailable. This means that you have unlabeled data.Statement II:In unsupervised approaches the target, which is what the model is predicting, is provided. This is referred to as having labeled data because the target is labeled for every sample that you have in your data set.
A
Only Statement I is true
B
Only Statement 2 is true
C
Both Statements are false
D
Both Statements are true
Explanation: 

Detailed explanation-1: -Expert-Verified Answer Machine Learning technique that helps in answering the question and the group to which the data belongs to is Classification. * Classification in machine learning is a process of identifying to which of the set a group of experimental observations belongs.

Detailed explanation-2: -Underfitting refers to a model that can neither model the training data nor generalize to new data. An underfit machine learning model is not a suitable model and will be obvious as it will have poor performance on the training data.

Detailed explanation-3: -The validation set is used to evaluate a given model, but this is for frequent evaluation. We, as machine learning engineers, use this data to fine-tune the model hyperparameters.

Detailed explanation-4: -Answer-B) SVG Is not a machine learning algorithm.
