Nonlinear regression with python - Stack Overflow
Nonlinear regression adjusts parameters in a single equation; Interpolation such as linear or cubic-spline; Empirical regression such as deep learning; I created a script with Python gekko to demonstrate each of these.
math - Non-linear regression in C# - Stack Overflow
Jul 22, 2015 · Wikipedia says "This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable." so I don't think multivariate regression is the correct term here because the OP is using a single dependent variable. –
statsmodels: specifying non-linear regression models using patsy
May 21, 2013 · Patsy isn't really useful for fitting general non-linear models, but the models on the page you link to are a special sort of non-linear model -- they're using a linear model fitting method (OLS), and applying it to non-linear transformations of the basic variables.

How to get scikit learn to find simple non-linear relationship
You should easily be able to get a decent fit using random forest regression, without any preprocessing, since it is a nonlinear method: model = RandomForestRegressor(n_estimators=10, max_features=2) model.fit(features, labels) You can play with the parameters to get better performance.

How do I do multivariate non-linear regression in Python?
Apr 29, 2019 · Please refer to the user guide for code examples of how this method can be used on regression problems. Please also note that the documentation states that. scikit-learn 0.21 introduces two new experimental implementations of gradient boosting trees, namely HistGradientBoostingClassifier and HistGradientBoostingRegressor, inspired by LightGBM.
Calculation of R^2 value for a non-linear regression
I would first like to say, that I understand that calculating an R^2 value for a non-linear regression isn't exactly correct or a valid thing to do. However, I'm in a transition period of performing most of our work in SigmaPlot over to R and for our non-linear (concentration-response) models, colleagues are used to seeing an R^2 value ...
python - non-linear regression by Pytorch - Stack Overflow
Jul 1, 2019 · I am trying to implement a non-linear regression task using PyTorch framework. The inputs are sample sentences and the targets are their scores (these scores are some float numbers). In order for the computer to understand the sentences, I convert each sentence to a 50 dimensional real vector (embedding vectors) using a torch.nn.RNN (Recurrent ...
Non-linear regression in Seaborn Python - Stack Overflow
Sep 30, 2017 · I have the following dataframe that I wish to perform some regression on. I am using Seaborn but can't quite seem to find a non-linear function that fits. Below is my code and it's output, and below that is the dataframe I am using, df. Note I have truncated the axis in this plot.
