5 Hyperparameter Optimization Methods Every Data Scientist Should Use

Before starting our quest for our best model, we want to find a dataset and a model first. We chose to use Amazon Us Reviews. The goal is to predict its target feature (the number of stars attributed) using customer reviews. Below, we're defining the model whose hyperparameters we will try to optimize: If you're not familiar with pipelines, don't hesitate to check out our previous article! Before we get to the optimization part, we first need to know what are our model's hyperparameters, right?
