A percentage (usually around the 70%) that can be used for the training of the model, called training set. The rest of the data will play as the validation set and it will be used to evaluate the performance of the model when it receives data that has never seen. A percentage (usually around the 70%) that can be used for the training of the model, called training set. The rest of the data will play as the validation set and it will be used to evaluate the performance of the model when it receives data that has never seen. For more complex types of model, often a small percentage (usually 5% to 10% of all the datasets) is reserved for an additional evaluation of the performance, after that the model shows good results also on the validation set.
