Artificial intelligence is a hot topic now. With the growth of accumulated information, the demand for specialists with skills to handle this amount of data is growing. And the question is not limited to the selection of the right tools. The specialist must be well oriented both in technical terms and in the business whose data he processes. In turn, the technical aspect is not limited to the knowledge of only one language. Often this implies knowledge of several languages, the ability to build a system in a heterogeneous environment, as well as knowledge of advanced mathematics and applied statistics.

The entrance threshold to the specialty is quite high. It’s required not only to accumulate knowledge, but also to learn to understand the data and correctly apply the tools. There is a growing number of Massive Open Online Course (MOOC) which can help with the start and further in this article you’ll find a list of them which you can use to get started. In order to make this list relevant. I took reviews and feedback of participants from several Data Science communities. But before diving deeper with courses let’s recap what is Data Science and which skills you will need.

Data Science Specialist Profile

Data Science is a very broad topic. When I first met with this discipline, I remember my confusion because of the number of necessary skills that I had to learn. But if you move with small steps everything is possible. The entire discipline can be divided into two major specializations: Data Scientist and Data Engineer. There are many articles about their differences and skills. For example, this one O’Reilly Data engineers vs. data scientists. In my article, I will only summarize the final view. Most likely you’re questioning yourself which language you have to learn Python or R.

My personal opinion is that if you want to move towards the Date Scientist specialty you should learn R, and if vice versa, then Python. Since I have a background of backend developer I tend to choose Python and the further recommendations will be focused more on Data Engineer specialization. Bear in mind that this discipline is a cross-road of different practices and brings everything together. It means that if we’re talking about database development it may include not only relational databases, but also NoSQL, and also different vendors. Or it maybe cloud storage or some files stored on the disk. The person should have enough experience to understand which tool and in when to use.

Common for both specializations is Data Science concepts could be as follows:

  1. Learning types: supervised, unsupervised, reinforce
  2. Basics of Neural Networks
  3. Basics of Application Statistic and Advanced Mathematics
  4. Understanding tasks which could be solved:
    1. classification
    2. forecasting
    3. clustering

Data Engineer should dig into the following topics:

  1. Programming languages such as Python, R
    1. basics and concepts
    2. ML/DL APIs: Pandas, Scikit-learn, Tensorflow, etc.
  2. The building of ETL pipelines: Hadoop, Spark, Map-Reduce, etc.
  3. Cloud services and Data warehouse architecture
  4. Distributed and service-oriented architecture
  5. Deeper knowledge of Neural Networks

Data Scientist should dig into the following topics:

  1. Flawless understanding of Application Statistic and Advanced Mathematics
  2. Flawless understanding of Regression, Classification, Clusterization
  3. Understanding of DL models development (RNN, Dense, Convolutional)
  4. Fluent in DL/ML (Statistics, Fraud/Anomaly detection, user segmentation, recommendation systems, A/B testing) and Data Analytics

Distinguish Two Roles

And last but not least. Don’t be mislead with this picture which is used often all over the internet. You as a future specialist should teach your managers to distinguish these two roles and do not expect from one person to know all aspects of the discipline. The right skill set and smart application of it is the key factor to get benefits from this practice.

MOOC Courses

Keeping everything above in mind, I and my colleagues from Data Science Society created this list for those of you how is just starting with this discipline. We’ll try to update the list from time to time adding more relevant courses for both specializations. We will appreciate your feedback in the comments section about the courses which you participated in.

If you’re keen on learning Data Science and want to learn together with other enthusiasts you can subscribe to Data Science Society Data.Chat and enroll to the FB group to stay in tune.

All courses are divided into several areas:

  1. Programming Languages
  2. Mathematics and Statistics
  3. Machine Learning
  4. Deep Learning and Neural Networks
  5. Data Engineer Concepts

I chose only a few courses in each of the areas which have good feedback from communities.

Machine Learning supervised, unsupervised learning, bias/variance theory, neural networks 3 80 The course is conducted by Andrew Ng, who is a well-known person in Data Science. The course covers such aspects as supervised learning (parametric/non-parametric algorithms, support vector machines, kernels, neural networks). (ii) unsupervised learning (clustering, dimensionality reduction, recommender systems, deep learning), bias/variance theory. This just a very good course to get started with Data Science.

Length & Price

Length and prices are approximate. Some of the mentioned courses are available for free and only certification requires investments. Free access can vary from platform to platform and from course to course. For example, Coursera may hide assessments behind the paywall, when materials are available. On edX the only certificate is paid.
