Course Description
Welcome to the course on Data Science & Deep Learning for Business™ 20 Case Studies!
This course teaches you how Data Science & Deep Learning can be used to solve real-world business problems and how you can apply these techniques to 20 real-world case studies.
Traditional Businesses are hiring Data Scientists in droves, and knowledge of how to apply these techniques in solving their problems will prove to be one of the most valuable skills in the next decade!
What student reviews of this course are saying,
"I'm only half way through this course, but i have to say WOW. It's so far, a lot better than my Business Analytics MSc I took at UCL. The content is explained better, it's broken down so simply. Some of the Statistical Theory and ML theory lessons are perhaps the best on the internet! 6 stars out of 5!"
"It is pretty different in format, from others. The appraoch taken here is an end-to-end hands-on project execution, while introducing the concepts. A learner with some prior knowledge will definitely feel at home and get to witness the thought process that happens, while executing a real-time project. The case studies cover most of the domains, that are frequently asked by companies. So it's pretty good and unique, from what i have seen so far. Overall Great learning and great content."

"Data Scientist has become the top job in the US for the last 4 years running!" according to Harvard Business Review & Glassdoor.
However, Data Science has a difficult learning curve - How does one even get started in this industry awash with mystique, confusion, impossible-looking mathematics, and code? Even if you get your feet wet, applying your newfound Data Science knowledge to a real-world problem is even more confusing.
This course seeks to fill all those gaps in knowledge that scare off beginners and simultaneously apply your knowledge of Data Science and Deep Learning to real-world business problems.
This course has a comprehensive syllabus that tackles all the major components of Data Science knowledge.

News Headline Classification
“Big data is at the foundation of all the megatrends that are happening.”
Businesses NEED Data Scientists more than ever. Those who ignore this trend will be left behind by their competition. In fact, the majority of new Data Science jobs won't be created by traditional tech companies (Google, Facebook, Microsoft, Amazon, etc.) they're being created by your traditional non-tech businesses. The big retailers, banks, marketing companies, government institutions, insurances, real estate and more.
"Consumer data will be the biggest differentiator in the next two to three years. Whoever unlocks the reams of data and uses it strategically will win.”
With Data Scientist salaries creeping up higher and higher, this course seeks to take you from a beginner and turn you into a Data Scientist capable of solving challenging real-world problems.

Hi I'm Rajeev, a Data Scientist, and Computer Vision Engineer.
I have a BSc in Computer & Electrical Engineering and an MSc in Artificial Intelligence from the University of Edinburgh where I gained extensive knowledge of machine learning, computer vision, and intelligent robotics.
I have published research on using data-driven methods for Probabilistic Stochastic Modeling for Public Transport and even was part of a group that won a robotics competition at the University of Edinburgh.
I launched my own computer vision startup that was based on using deep learning in education since then I've been contributing to 2 more startups in computer vision domains and one multinational company in Data Science.
Previously, I worked for 8 years at two of the Caribbean’s largest telecommunication operators where he gained experience in managing technical staff and deploying complex telecommunications projects.

I am new to AI, and this course was absolutely amazing in explaining what everything is, and how it actually works. This course literally combined 15+ years of education and experience into 21+ hours. Now I just need to spend the next 6 months going back over everything and working through all of the code myself to truly even begin to understand. Thank you!
By Deepika Sampangi on 3/6/2022
The Course covers good number of use cases, but they are not very detailed drilled into, like understanding the outcome of models and which features are impacting the result, over all it is a good course for a beginner to get an idea of what all possible use cases can be handled using DS and DL
By Monica Alicea on 10/19/2021
I have never before understood probability and statistics with such clarity before. I went into this course thinking it would give me cool projects to practice machine learning with but I've come out understanding everything I never understood in my many years of prob and stat courses!

In the middle of the course we stopped getting videos. Although the notebooks are quite comprehensive, I feel like I needed the accompanying videos to walk me through the lessons. Especially because the latter lessons with the more interesting (in my opinion) case studies are the ones missing the commentary. The slides are good, but I would prefer if you were explaining things further when showcasing slides, instead of just reading what's there. Overall is a course with good material, but the presentation of the material could be improved.
By Carlos Andrés Campo González on 5/29/2021
Excellent. I didn't want yet another course teaching me the basics, I needed a portfolio of tools to use in my daily work and this is the closest I've found. Although broad and superficial at times (every single chapter can have it's own course with different case studies), this is exactly the kind of course one needs more of - less of a tutorial than a real hands-on exercise. Hopefully the author makes many more, diving in on particular subjects (although that would seem hard for him to do alone, to pass from the basics to the complex in a subject one needs true industry expertise...hopefully a colab can help?). Great job.
By Eric Esajian on 4/17/2020
The instructor has a lot of data science knowledge and explains the concepts very clearly. This is a loaded course with a lot of really good information. He's got a good voice for teaching so it was easy to pay attention to the course concepts. I hope he continues making python courses!
By Anonymized User on 12/23/2019
For the kind of study I am most interested in, I would say that the teacher glosses over key math concepts and focuses on the intuition behind it. I respect this approach since the class is more oriented towards the 20 Case Studies. Overall, I very much appreciate the fluidity of the lessons and the wide range of topics covered. I would recommend this course for those who wish to just have a very rapid overview of ML techniques and to start applying the Python code - it takes way more time to digest and learn the maths of ML.
By Anonymized User on 12/18/2019
Excellent overview of the key topic areas of ML. Course is supported by plenty of practical examples that provide hands-on experience and reinforce learning with the types of problems one is likely to encounter in the world. Some of the lessons are jerky due to jumping quickly in and out of different slides. Slower transitions or a more calculated approach would soften these sometimes hard edges.

It is pretty different in format, from others. The appraoch taken here is an end-to-end hands-on project execution, while introducing the concepts. A learner with some prior knowledge will definitely feel at home and get to witness the thought process that happens, while executing a real-time project. The case studies cover most of the domains, that are frequently asked by companies. So it's pretty good and unique, from what i have seen so far. After finishing the course: There are some case studies, without the video explaining what's going on with the code. Some of these case studies are difficult for a beginner, to wrap their head around and understand what's going on, with the code provided. Adding explanatory videos, for these just like other case studies in the beginning, will improve the learning experience by a great extent. Hope Rajeev manages to add these videos to the course. Overall Great learning and great content.
By Asheesh Mathur on 11/27/2019
Wonderful coverage of topics. Presents realistic industry picture of the roles played by different roles. Covers all relevant topics required for successful implementation of projects. Collection of case studies goes a long way in hammering usage.
