This course will increase your skills to crack the data science or machine learning interview. You will cover all the most common data science and ML concepts coupled with relevant interview questions.
You will start by covering Python basics as well as the most widely used algorithms and data structures. From there, you will move on to more advanced topics like feature engineering, unsupervised learning, as well as neural networks and deep learning.
This course takes a non-traditional approach to interview prep, in that it focuses on data science fundamentals instead of open-ended questions.

In all, this course will get you ready for data science interviews. By the time you finish this course, you will have reviewed all the major concepts in data science and will have a good idea of what interview questions you can expect.

Data Science Interview Handbook

Overfitting is when the model gives low error on training data but a  high error on testing data. You learned about overfitting in the previous lesson. A highly complex model leads to overfitting. In regression, overfitting refers to large values of coefficients. When the value of coefficients is very high, that coefficient dominates, leading to overfitting.


Learn about the two techniques for handling overfitting in regression: Ridge and Lasso regression.
