What is validation set in machine learning?
A validation set is a set of data used to train artificial intelligence (AI) with the goal of finding and optimizing the best model to solve a given problem. Validation sets are also known as dev sets. Validation sets are used to select and tune the final AI model.
Can validation and test set be the same?
Generally, the term “validation set” is used interchangeably with the term “test set” and refers to a sample of the dataset held back from training the model. The evaluation of a model skill on the training dataset would result in a biased score.
What is the difference between test and Validation datasets?
From this perspective, your questions can be answered as follows: Validation set is used for determining the parameters of the model, and test set is used for evaluate the performance of the model in an unseen (real world) dataset Validation set is optional, and it is aimed to avoid over-fitting problem. Again, the validation set is for tuning the parameters, and the test set is used for the evaluation purposes.

A validation set is a set of data used to train artificial intelligence (AI) with the goal of finding and optimizing the best model to solve a given problem.
What is evaluation in machine learning?
While on the other hand, evaluation in machine learning refers to assessment or test of entire machine learning model and its performance in various circumstances. It involves assessment of machine learning model training process, deep learning algorithms performance and how accurate is the predictions given in different situations.
What is machine learning testing?
The test for a machine learning model is a validation error on new data, not a theoretical test that proves a null hypothesis. Because machine learning often uses an iterative approach to learn from data, the learning can be easily automated. Passes are run through the data until a robust pattern is found.
