Video description

New to machine learning? This is the place to start: Linear regression, Logistic regression, and Cluster Analysis

About This Video

  • Learn machine learning with StatsModels and sklearn
  • Apply machine learning skills to solve real-world business cases
  • Get started with linear regression, logistic regression, and cluster analysis

In Detail

Machine Learning is one of the fundamental skills you need to become a data scientist. It's the steppingstone that will help you understand deep learning and modern data analysis techniques.

In this course, you'll explore the three fundamental machine learning topics - linear regression, logistic regression, and cluster analysis. Even neural networks geeks (like us) can't help but admit that it's these three simple methods that data science revolves around. So, in this course, we will make the otherwise complex subject matter easy to understand and apply in practice. This course supports statistics theory with practical application of these quantitative methods in Python to help you develop skills in the context of data science.

We've developed this course with not one but two machine learning libraries: StatsModels and sklearn. You'll be eager to complete this course and get ready to become a successful data scientist!
