How do you deal with multicollinearity in categorical variables?

Conclusion: In this article, we have discussed how to avoid multicollinearity in categorical data. Lasso regularization can also be used to avoid the effect of multicollinearity. By choosing the correct value of alpha for lasso regularization the weight of the extra features will be equated to zero.
