A study of model and hyper-parameter selection strategies ...

2020-10-30  It is well known that machine learning (ML) techniques have been playing an important role in several real world applications. However, one of the main challenges is the selection of the most accurate technique to be used in a specific application. In the classification context, for instance, two main approaches can be applied, model selection and hyper-parameter selection. In the first ...

Model Parameters and Hyperparameters in Machine

2019-10-30  In a machine learning model, there are 2 types of parameters: Model Parameters: These are the parameters in the model that must be determined using the training data set. These are the fitted parameters. Hyperparameters: These are adjustable parameters that must be tuned in order to obtain a model with optimal performance. For example, suppose you want to build a simple linear regression model ...
