Nettetlinear and Generalized linear models can be regularized to decrease their variance at the cost of increasing their bias. [10] In artificial neural networks , the variance increases and the bias decreases as the number of hidden units increase, [11] although this classical assumption has been the subject of recent debate. [4] Nettet18. mai 2024 · Introduction. Linear Models are considered the Swiss Army Knife of models. There are many adaptations we can make to adapt the model to perform well on a variety of conditions and data types. Generalised Additive Models (GAMs) are an adaptation that allows us to model non-linear data while maintaining explainability.
