Description

Learn Python for Data Science & Machine Learning from A-Z

In this practical, hands-on course you’ll learn how to program using Python for Data Science and Machine Learning. This includes data analysis, visualization, and how to make use of that data in a practical manner.

Our main objective is to give you the education not just to understand the ins and outs of the Python programming language for Data Science and Machine Learning, but also to learn exactly how to become a professional Data Scientist with Python and land your first job.

We'll go over some of the best and most important Python libraries for data science such as NumPy, Pandas, and Matplotlib +

  • NumPy —  A library that makes a variety of mathematical and statistical operations easier; it is also the basis for many features of the pandas library.

  • Pandas — A Python library created specifically to facilitate working with data, this is the bread and butter of a lot of Python data science work.

NumPy and Pandas are great for exploring and playing with data. Matplotlib is a data visualization library that makes graphs as you’d find in Excel or Google Sheets. Blending practical work with solid theoretical training, we take you from the basics of Python Programming for Data Science to mastery.

This Machine Learning with Python course dives into the basics of machine learning using Python. You'll learn about supervised vs. unsupervised learning, look into how statistical modeling relates to machine learning, and do a comparison of each.

We understand that theory is important to build a solid foundation, we understand that theory alone isn’t going to get the job done so that’s why this course is packed with practical hands-on examples that you can follow step by step. Even if you already have some coding experience, or want to learn about the advanced features of the Python programming language, this course is for you!

Python coding experience is either required or recommended in job postings for data scientists, machine learning engineers, big data engineers, IT specialists, database developers, and much more. Adding Python coding language skills to your resume will help you in any one of these data specializations requiring mastery of statistical techniques.

Together we’re going to give you the foundational education that you need to know not just on how to write code in Python, analyze and visualize data and utilize machine learning algorithms but also how to get paid for your newly developed programming skills.

I would like to include more libraries like Tensorflow and Cloud tools like Google Cloud Platform and integration with big data like SQL for data science with IBM db2 engine for example. I took EDX SQL for Data Science sincerely I would like to see a course seems like this here.

Buen curso en una vista general. Abarca muchos temas lo cual ayuda a tener un buen panorama del tema central en cuestión. Pero las clases están algo desordenadas y faltan varios proyectos mencionados. Pero en definitiva fue una gran experiencia y me servirá mucho

The information in the course very useful for beginners, but here is no functionality to control students knowledge

This course is perhaps best for it's introduction to supervised machine learning methods, and that it performs phenomenally well. There is a little discussion about practical applications of each method, details about the mathematical underpinnings, and implementation in Python from scratch. However, unsupervised learning just focused on defining jargon and it's relation to techniques. The rest of the course is adequate to get started with practicing machine learning, but perhaps lacks a bit as far as subjects like data cleaning. I still highly recommend the course because the supervised machine learning portion is superb.

I'm getting a deeper understanding of what machine learning means, beyond the concept. You'll leave this course with a pretty good grasp of the steps, pros and cons, and techniques used in machine learning, and even you'd be able to choose the best model for your project. But I think you wont be able to implement it from scratch by only taking this course. Its a good kickstart to further learning. You dont get the notebooks used during the course, the good part is that you have to code everithing yourself and its part of the learning process. The bad part is that if you get some bug and you dont know how to fix it, you dont have anywhere to look up for the right code. I couldnt run the decision trees models from scratch for example, because I've got stuck with bugs. Thats the only thing I dindt like.

Section 4 till Section 13, all were explained in a hurry. Very less content. And more of a slide reading.

I think the course is very well explained, the presenter does good emphasis on important points. And having as an introduction to the course how someone needs to approach a job interview is a fantastic idea, as it makes your brain more focused and aimed oriented. Good job
