Model tuning

Model tuning

Hyperparameters can be thought of as the external controls that influence how the model operates, just as flight instruments control how an aeroplane flies. These values are external to the model and are controlled by the user. They can influence how an algorithm is trained and the structure of the final model. The optimized settings…

How to select a model for a given machine learning problem

How to select a model for a given machine learning problem

To select a model for a given Machine Learning problem we use the information and conclusions from Framing the Problem. A Machine Learning problem can be described with four aspects: The first aspect concerns the format and structure of the data, which could be numeric, images or text. Numeric data is often tabular. The second…
