Small datasets and few features are a domain where traditional statistical models tend to do very well, because they offer the ability to actually interpret the importance of your features. I'm assuming by "simple regression" you mean predicting a real-valued, continuous variable y from your input variables.

NettetSuggestion - Use the "swish" function in the hidden layer and the "linear" function in output layer, if you are dealing with negative output regression. Cite 2 Recommendations NettetIn linear regression, the model specification is that the dependent variable, is a linear combination of the parameters (but need not be linear in the independent variables). For example, in simple linear regression for modeling n {\displaystyle n} data points there is one independent variable: x i {\displaystyle x_{i}} , and two parameters, β 0 …
