*** Python Neural Networks with TensorFlow 7 : Text Classification P3 - Validation Data - Training the Model - Testing the Model ***  Text-Based Tutorial: https://techwithtim.net/tutorials/pyt... *** About Train, Validation and Test Sets in Machine Learning ● Training Dataset - The sample of data used to fit the model. - The actual dataset that we use to train the model (weights and biases in the case of Neural Network). The model sees and learns from this data ● Validation Dataset - The sample of data used to provide an unbiased evaluation of a model fie on the training dataset while tuning model hyperparameters. The evaluation becomes more biased as skill on the validation dataset is incorporated into the model configuration. - 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. Hence the model occasionally sees this dat...
