There are plenty of links for simple, practical, and efficient coding solutions, hand-picked books, and videos organized within modules below to cover; Data Structures, Computer Science Algorithms, Data Analysis Examples, and Machine Learning Applications.

Note: Starting from Module2, make sure to have a working Ipython (jupyter) notebook to be able to view, use, and edit the .ipynb files. It is recommended to install Miniconda and then work on the environments you need. With the conda package management system, install: 'numpy', 'scipy', 'matplotlib', 'sklearn', 'torch', and 'pandas' libraries to be able to run the code in the jupyter notebooks.

Wait! I want to learn data science & machine learning step by step

Module1: Start Here! Learn Coding with Python & Javascript

Fix your typing first. Start learning Python right away. Study and practice coding a few hours a day, every day. Cover every single topic in this document thoroughly and create your .py notebooks.If you want to go deep in coding, also study Javascript in parallel.

Done? Now you know how to code! Click here to quit the data science track and become a web developer instead!

Module3: Data Structures, CS Algorithms & Intro to ML

Study these DS & CS Algorithms:

BST, Decision Trees, Random Forest, Linked Lists, Graph SPT & Heap, Graph MST, DFT & FFT, Sorting Algorithms, Bipartite Matching & Max Flow, Dynamic Programming, Stacks, Queues & Heaps, BFS & DFS, Greedy Algorithms, ML: Intro to NLP, ML: KNN, ML: Kmeans++, ML: 2LayerNN

together with: CS231 Then study: R, Big Data with Scala & Spark

+Learn: NoSQL/SQL, data warehousing, hadoop, Java, and cloud computing to become a data or software engineer.

Good job!
Hope you enjoyed the machine learning engineering ride with empirical, easy, and simplified solutions built with commonly used algorithms. This is just the beginning. The real-world problems will be harder and more complex but now you are ready to tackle them.
If you made it all the way here by carefully following all the 5 steps above, or passed a coding interview with the help of these solutions, maybe it is your time to contribute! If you want to donate, it is just one click away.
Please pass your knowledge and experience to others who need help.
