This classification algorithm has the identical instinct as linear regression simply that now we’ll use it to unravel a classification downside.
For higher understanding let’s first construct the instinct utilizing simply 2 characteristic datasets (known as Easy Linear Classification) in order that we are able to visualize ideas after which we’ll later extrapolate issues to N characteristic dataset (known as Multi Linear Classification).
Formulating Optimisation Drawback / Value Operate Derivation
Now primarily based on the above logic we should devise a value perform..
Inference
Overfitting
If the issue is totally linearly separable i.e. you may calculate a line such that it separates each the lessons with none misclassification then the coaching error will at all times be zero in a very linear classification mannequin. Therefore the issue of overfitting. We are able to use the identical strategies as mentioned in linear regression to unravel the overfitting downside.
