What is the difference between linear regression and logistic regression?
Linear regression | Logistic regression |
---|---|
It is a regression model, which means it will give a non-discrete/continuous output of a function. This approach provides the value. For example: given x what is f(x) | It is a binary classification algorithm, which means that here there will be discrete-valued output for the function. For instance: for a given x if f(x)>threshold arrange it to be 1 else group it to be 0. |
It uses an ordinary method of least squares method to minimize the errors | It uses maximum likelihood methods to reach the answer. |
It gives an equation that is of the shape Y = mX + C, which means equation with degree 1. | gives an equation which is of the shape Y = eX + e-X |
