Questions tagged [non-linear-regression]
In statistics, nonlinear regression is a form of regression analysis in which observational data are modeled by a function which is a nonlinear combination of the model parameters and depends on one or more independent variables. The data are fitted by a method of successive approximations. It is used in place when the data shows a curvy trend, and linear regression would not produce very accurate results when compared to non-linear regression.

Expected Revenue Using Gradient Boost for Regression
I have trained a ML algorithm (gradient boost) to do regression on banana prices, such that I can guess the selling price of any given banana. Using scikit's regression boost algorithm, I am able to ...

Does a second-order fully-connected layer have any uses?
I was thinking about implementing second-order regression via a fully-connected layer, and I came up with this:
$X$ is the input data, shaped $(features, batch\_number)$.
$w0$ is the bias, shaped $(...

What is the difference between neural networks and other ways of curve fitting?
For simplicity, let's assume we want to solve a regression problem, where we have one independent variable and one dependent variable, which we want to predict. Let's also assume that there is a ...

If features are always positives, why do we use RELU activation functions?
When does it happen that a layer (either first or hidden) outputs negative values in order to justify the use of RELU?
As far as I know, features are never negative or converted to negative in any ...

Regularization of non-linear parameters?
I was wondering whether it is possible to regularize (L1 or L2) non-linear parameters in a general regression model. Say, I have the following non-linear least squares cost function, where $p$ is a $...

What is the difference between linear and non-linear regression?
In machine learning, I understand that linear regression assumes that parameters or weights in equation should be linear. For Example:
$$y = w_1x_1 + w_2x_2$$
is a linear equation where $x_1$ and $...
