Non-Linear Models

Towards AI

When the formula looks nice but is hurting the analysis This is not my first blog concerning non-linear models. In fact, if you sift through my lists of blogs, you can see I applied quite a couple of...

PyTorch Introduction — Enter NonLinear Functions

Towards Data Science

Pytorch Introduction — Enter NonLinear Functions Continuing the Pytorch series, in this post we’ll learn about how non-linearities help solve complex problems in the context of neural networks Neural...

Simulating data from a non-linear function by specifying a handful of points

R-bloggers

Trying to simulate data with non-linear relationships can be frustrating, since there is not always an obvious mathematical expression that will give you the shape you are looking for. I’ve come up wi...

Explicit feature maps for non-linear kernel functions

Towards Data Science

How to generate and compact feature representation for non-linear kernels with applications to supervised and unsupervised machine learning problems.

Nonlinear Regression Tutorial with Radial Basis Functions

Analytics Vidhya

Let's take a look at basis function regression which allows us to model non-linear relationships. If you are familiar with regular linear regression, then you know the goal is to find parameters…

Non-linear SVM

Scikit-learn Examples

Non-linear SVM Perform binary classification using non-linear SVC with RBF kernel. The target to predict is a XOR of the inputs. The color map illustrates the decision function learned by the SVC.

ACTIVATION FUNCTIONS

Analytics Vidhya

Activation functions are the equations that determine the output of a neural network. The main purpose of an activation function is to introduce non-linearity to the neural network.

Activation Functions in Neural Networks

Towards Data Science

As you can see the function is a line or linear. Therefore, the output of the functions will not be confined between any range. It doesn’t help with the complexity or various parameters of usual data…...

Non-linear regression: basis expansion, polynomials & splines

Towards Data Science

Non-linear modelling with piecewise polynomials, cubic splines, natural splines and smoothing splines.

Classical Neural Net: Why/Which Activations Functions ?

Towards Data Science

Activation functions are a family of functions that holds the purpose of introducing non-linearity after a layer computation. Indeed without an activation function no matter how much augmentation or…

Modeling Non-Linear Dynamic Systems with Neural Networks

Towards Data Science

In mathematics and science, a nonlinear system is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems are of interest to engineers…
