Question 6Which of the following statements about datasets used in Machine Learning is NOT true?1 pointTesting data is data the model has never seen before and is used to evaluate how good the model isTraining subset is the data used to train the algorithm Training data is used to fine-tune algorithm’s parameters and evaluate how good the model isValidation data subset is used to validate results and fine-tune the algorithm's parameters

The _________ is a subset of the larger dataset, and it serves to provide the algorithm with a rudimentary understanding of the problem, solution, and data points to be handled.a)validation datasetb)accuracy scorec)test datasetd)interpretation datasete)training dataset

Regarding splitting datasets into training, validation, and test partitions, which ofthe following statements is true, if any?(i) The validation set is used multiple times to choose the best value forhyperparameters.(ii) The test set is used only once to determine the performance on unseen data.(iii) Improving performance on the validation set always improves performance onthe test set.

Question:  28of  4000:17Select the correct statement related to Validation and Test setAA validation set is used to tune the hyperparameters of a model, while a test set is used to evaluate its performanceBA validation set is used to evaluate the performance of a model in deployment, while a test set is used to evaluate its performance after trainingCA validation set and a test set are the same thingDA validation set is not necessary in machine learning
