Learn how to simulate and visualize data for data science, statistics, and machine learning in MATLAB and Python

Data science is quickly becoming one of the most important skills in industry, academia, marketing, and science. Most data-science courses teach analysis methods, but there are many methods; which method do you use for which data? The answer to that question comes from understanding data. That is the focus of this course.

What you will learn in this course:

You will learn how to generate data from the most commonly used data categories for statistics, machine learning, classification, and clustering, using models, equations, and parameters. This includes distributions, time series, images, clusters, and more. You will also learn how to visualize data in 1D, 2D, and 3D.

All videos come with MATLAB and Python code for you to learn from and adapt!

This course is for you if you are an aspiring or established:

  • Data scientist
  • Statistician
  • Computer scientist (MATLAB and/or Python)
  • Signal processor or image processor
  • Biologist
  • Engineer
  • Student
  • Curious independent learner!

What you’ll learn

  • Understand different categories of data
  • Generate various datasets and modify them with parameters
  • Visualize data using a multitude of techniques
  • Generate data from distributions, trigonometric functions, and images
