Dive into Machine Learning
Hi there! You might find this guide helpful if:
- You know Python or you’re learning it :snake:
- You’re new to Machine Learning
- You care about the ethics of ML
- You learn by doing
For some great alternatives, jump to the end or check out Nam Vu’s guide, Machine Learning for Software Engineers.
Of course, there is no easy path to expertise. Also, I’m not an expert! I just want to connect you with some great resources from experts. Applications of ML are all around us. I think it’s in the public interest for more people to learn more about ML, especially hands-on, because there are many different ways to learn.
Whatever motivates you to dive into machine learning, if you know a bit of Python, these days you can get hands-on with a machine learning “Hello World!” in minutes.
Let’s get started
Tools you’ll need
If you prefer local installation
- Python. Python 3 is the best option.
- Jupyter Notebook. (Formerly known as IPython Notebook.)
- Some scientific computing packages:
You can install Python 3 and all of these packages in a few clicks with the Anaconda Python distribution. Anaconda is popular in Data Science and Machine Learning communities. (Use whichever tool you want.)
Some options you can use from your browser:
- Binder is Jupyter Notebook’s official choice to try JupyterLab
- Deepnote allows for real-time collaboration
- Google Colab provides “free” GPUs
For other options, see:
- markusschanta/awesome-jupyter, “Hosted Notebook Solutions”
- ml-tooling/best-of-jupyter, “Notebook Environments”
Learn how to use Jupyter Notebook (5-10 minutes). (You can learn by screencast instead.)
Now, follow along with this brief exercise: An introduction to machine learning with scikit-learn. Do it in
ipython or a Jupyter Notebook, coding along and executing the code in a notebook.
What just happened?
You just classified some hand-written digits using scikit-learn. Neat huh?
A Visual Introduction to Machine Learning
Let’s learn a bit more about Machine Learning, and a couple of common ideas and concerns. Read “A Visual Introduction to Machine Learning, Part 1” by Stephanie Yee and Tony Chu.
It won’t take long. It’s a beautiful introduction … Try not to drool too much!
A Few Useful Things to Know about Machine Learning
OK. Let’s dive deeper.
Read “A Few Useful Things to Know about Machine Learning” by Prof. Pedro Domingos. It’s densely packed with valuable information, but not opaque.
Take a little time with this one. Take notes. Don’t worry if you don’t understand it all yet.
The whole paper is packed with value, but I want to call out two points:
- Data alone is not enough. This is where science meets art in machine-learning. Quoting Domingos: “… the need for knowledge in learning should not be surprising. Machine learning is not magic; it can’t get something from nothing. What it does is get more from less. Programming, like all engineering, is a lot of work: we have to build everything from scratch. Learning is more like farming, which lets nature do most of the work. Farmers combine seeds with nutrients to grow crops. Learners combine knowledge with data to grow programs.”
- More data can beat a cleverer algorithm. Listen up, programmers. We like cool tools. Resist the temptation to reinvent the wheel, or to over-engineer solutions. Your starting point is to Do the Simplest Thing that Could Possibly Work. Quoting Domingos: “Suppose you’ve constructed the best set of features you can, but the classifiers you’re getting are still not accurate enough. What can you do now? There are two main choices: design a better learning algorithm, or gather more data. […] As a rule of thumb, a dumb algorithm with lots and lots of data beats a clever one with modest amounts of it. (After all, machine learning is all about letting data do the heavy lifting.)”
When you work on a real Machine Learning problem, you should focus your efforts on your domain knowledge and data before optimizing your choice of algorithms. Prefer to do simple things until you have to increase complexity. You should not rush into neural networks because you think they’re cool. To improve your model, get more data. Then use your knowledge of the problem to explore and process the data. You should only optimize the choice of algorithms after you have gathered enough data, and you’ve processed it well.

- Another handy term: “Data Engineering.”
Just about time for a break…
Totally optional: some podcast episodes of noteFirst, download [an interview with Prof. Domingos on the _Data Skeptic_podcast](https://dataskeptic.com/blog/episodes/2018/the-master-algorithm) (2018). Prof. Domingos wrote [the paper we read earlier](http://homes.cs.washington.edu/~pedrod/papers/cacm12.pdf). You might also start reading his book, [_The Master Algorithm_ by Prof. Pedro Domingos](https://www.goodreads.com/book/show/24612233-the-master-algorithm), a clear and accessible overview of machine learning. (It's available as an audiobook too.) Next, subscribe to more machine learning and data science podcasts! These are great, low-effort resources that you can casually learn more from. To [learn effectively](https://www.coursera.org/learn/learning-how-to-learn), listen over time, with plenty of headspace. [By the way, don't speed up technical podcasts, that can hinder your comprehension.](https://www.theringer.com/2017/8/2/16095364/inefficiency-week-podcasts-speed-comprehension-f0ea43949e42) Subscribe to _**[Talking Machines](http://www.thetalkingmachines.com/)**_. I suggest this listening order: * **Download the ["Starting Simple"](http://www.thetalkingmachines.com/episodes/starting-simple-and-machine-learning-meds) episode, and listen to that soon.** It supports what we read from Domingos. [Ryan Adams](http://people.seas.harvard.edu/~rpa/) talks about starting simple, as we discussed above. Adams also stresses the importance of feature engineering. Feature engineering is an exercise of the "knowledge" Domingos writes about. In a later episode, [they share many concrete tips for feature engineering](https://www.thetalkingmachines.com/episodes/software-and-statistics-machine-learning). * Then, over time, you can listen to the entire podcast series (start from the beginning). Want to subscribe to more podcasts? Here's [a good listicle](https://towardsdatascience.com/5-data-science-ai-and-machine-learning-podcasts-to-listen-to-now-e5078b18d184) of suggestions, [and another](https://mty.ai/blog/the-best-ai-podcasts/).
OK! Take a break, come back refreshed.
Play to learn
Next, play along from one or more of notebooks.
- Dr. Randal Olson’s Example Machine Learning notebook: “let’s pretend we’re working for a startup that just got funded to create a smartphone app that automatically identifies species of flowers from pictures taken on the smartphone. We’ve been tasked by our head of data science to create a demo machine learning model that takes four measurements from the flowers (sepal length, sepal width, petal length, and petal width) and identifies the species based on those measurements alone.”
- Various notebooks by topic:
- Notebooks in a series:
- ageron/handson-ml2 - “Jupyter notebooks that walk you through the fundamentals of Machine Learning and Deep Learning in Python.” Scikit-Learn, Keras, TensorFlow 2.

Pick one of the courses below and start on your way.
Recommended course: Prof. Andrew Ng’s Machine Learning on Coursera
Prof. Andrew Ng’s Machine Learning is a popular and esteemed free online course. I’ve seen it recommended often. And emphatically.
You might like to have a pet project to play with, on the side. When you are ready for that, you could explore one of these Awesome Public Datasets, paperswithcode.com/datasets, or datasetlist.com.
Also, it’s recommended to grab a textbook to use as an in-depth reference. The two I saw recommended most often were Understanding Machine Learning and Elements of Statistical Learning. You only need to use one of the two options as your main reference; here’s some context/comparison to help you pick which one is right for you. You can download each book free as PDFs at those links - so grab them!
Tips for this course

Tips for studying on a busy schedule
It’s hard to make time available every week. So, you can try to study more effectively within the time you have available. Here are some ways to do that:
- “Learning How to Learn” by Barbara Oakley by Barbara Oakley, a free video course on Coursera.
- Prefer book/audiobook? These are great options:
- Barbara Oakley’s book A Mind for Numbers: How to Excel at Math and Science (reviews) — “We all have what it takes to excel in areas that don’t seem to come naturally to us at first”
- Make It Stick: the Science of Successful Learning (reviews)
Take my tips with a grain of salt
I am not a machine learning expert. I’m just a software developer and these resources/tips were useful to me as I learned some ML on the side.
- Data science courses as Jupyter Notebooks:
microsoft/Data-Science-For-Beginners— added in 2021 — “10-week, 20-lesson curriculum all about Data Science. Each lesson includes pre-lesson and post-lesson quizzes, written instructions to complete the lesson, a solution, and an assignment. Our project-based pedagogy allows you to learn while building, a proven way for new skills to ‘stick’.”

Assorted Tips and Resources
“Machine learning systems automatically learn programs from data.” Pedro Domingos, in “A Few Useful Things to Know about Machine Learning.” The programs you generate will require maintenance. Like any way of creating programs faster, you can rack up technical debt.
Here is the abstract of Machine Learning: The High-Interest Credit Card of Technical Debt:
Machine learning offers a fantastically powerful toolkit for building complex systems quickly. This paper argues that it is dangerous to think of these quick wins as coming for free. Using the framework of technical debt, we note that it is remarkably easy to incur massive ongoing maintenance costs at the system level when applying machine learning. The goal of this paper is highlight several machine learning specific risk factors and design patterns to be avoided or refactored where possible. These include boundary erosion, entanglement, hidden feedback loops, undeclared consumers, data dependencies, changes in the external world, and a variety of system-level anti-patterns.
If you’re following this guide, you should read that paper. You can also listen to a podcast episode interviewing one of the authors of this paper.

What are some ways to practice?
One way: competitions and challengesYou need **practice.** [On Hacker News, user olympus commented to say you could use competitions to practice and evaluate yourself](https://news.ycombinator.com/item?id=10508565). [Kaggle](https://www.kaggle.com/competitions) and [ChaLearn](http://www.chalearn.org/) are hubs for Machine Learning competitions. (You can find more competitions [here](https://github.com/paperswithcode/releasing-research-code#results-leaderboards) or [here](https://towardsdatascience.com/12-data-science-ai-competitions-to-advance-your-skills-in-2021-32e3fcb95d8c).) You also need **understanding.** You should review what Kaggle competition winners say about their solutions, [for example, the "No Free Hunch" blog](http://blog.kaggle.com/). These might be over your head at first but once you're starting to understand and appreciate these, you know you're getting somewhere. Competitions and challenges are just one way to practice! [Machine Learning isn't just about Kaggle competitions](https://jvns.ca/blog/2014/06/19/machine-learning-isnt-kaggle-competitions).
Another way: try doing some practice studiesHere's a complementary way to practice: **do practice studies.** 1. **Ask a question. Start exploring some data.** The ["most important thing in data science is the question"](https://github.com/DataScienceSpecialization/courses/blob/master/01_DataScientistToolbox/03_02_whatIsData/index.Rmd#the-data-is-the-second-most-important-thing) ([Dr. Jeff T. Leek](https://github.com/jtleek)). So start with a question. Then, find [real data](https://github.com/caesar0301/awesome-public-datasets). Analyze it. Then ... 2. **Communicate results.** When you think you have a novel finding, ask for review. When you're still learning, ask in informal communities (some are [linked below](#some-communities-to-know-about)). 3. **Learn from feedback.** Consider [learning in public](https://www.swyx.io/learn-in-public/), it works great for some folks. (Don't pressure yourself though! Do what works for you.) How can you come up with interesting questions? Here's one way. Pick a day each week to [look for public datasets](https://github.com/caesar0301/awesome-public-datasets) and write down some questions that come to mind. Also, sign up for [Data is Plural](https://tinyletter.com/data-is-plural), a newsletter of interesting datasets. When a question inspires you, try exploring it with the skills you're learning. This advice, to do practice studies and learn from review, is based on [a conversation](https://github.com/hangtwenty/dive-into-machine-learning/issues/11#issuecomment-153934120) with [Dr. Randal S. Olson](http://www.randalolson.com/). Here's more advice from Olson, [quoted with permission:](https://github.com/hangtwenty/dive-into-machine-learning/issues/11#issuecomment-154135498) > I think the best advice is to tell people to always present their methods clearly and to avoid over-interpreting their results. Part of being an expert is knowing that there's rarely a clear answer, especially when you're working with real data. As you repeat this process, your practice studies will become more scientific, interesting, and focused. Also, [here's a video about the scientific method in data science.](https://101.datascience.community/2012/06/27/the-data-scientific-method/))

- Lessons on ML Platforms from Netflix, DoorDash, Spotify, and more by Ernest Chan in Towards Data Science
- MLOps Stack Canvas at ml-ops.org
Recommended awesomelists to save/star/watch:
Take note: some experts warn us not to get too far ahead of ourselves, and encourage learning ML fundamentals before moving onto deep learning. That’s paraphrasing from some of the linked coursework in this guide — for example, Prof. Andrew Ng encourages building foundations in ML before studying DL. Perhaps you’re ready for that now, or perhaps you’d like to get started soon and learn some DL in parallel to your other ML learnings.
When you’re ready to dive into Deep Learning, here are some helpful resources.
- Dive into Deep Learning - An interactive book about deep learning (view on GitHub)
- “Implemented with NumPy/MXNet, PyTorch, and TensorFlow”
- “Adopted at 200 universities from 50 countries”
- “The entire book is drafted in Jupyter notebooks, seamlessly integrating exposition figures, math, and interactive examples with self-contained code.”
- “You can modify the code and tune hyperparameters to get instant feedback to accumulate practical experiences in deep learning.”
explosion/thincis an interesting library that wraps PyTorch, TensorFlow and MXNet models.
- “Concise functional-programming approach to model definition, using composition rather than inheritance.”
- “Integrated config system to describe trees of objects and hyperparameters.”
fastai/fastbookby Jeremy Howard and Sylvain Gugger — “an introduction to deep learning, fastai and PyTorch.”
- Prof. Andrew Ng’s courses on Deep Learning! There five courses, as part of the Deep Learning Specialization on Coursera. These courses are part of his new venture, deeplearning.ai
- Some course notes about it: ashishpatel26/Andrew-NG-Notes
- Deep Learning, a free book published MIT Press. By Ian Goodfellow, Yoshua Bengio and Aaron Courville.
- A notable testimonial for it is here: “What are the best ways to pick up Deep Learning skills as an engineer?”
- paperswithcode.com — “The mission of Papers with Code is to create a free and open resource with Machine Learning papers, code, datasets, methods and evaluation tables.”
labmlai/annotated_deep_learning_paper_implementations— “Implementations/tutorials of deep learning papers with side-by-side notes.” 50+ of them! Really nicely annotated and explained.
- JAX - official quickstart Colab Notebooks to get to know JAX
- Distill.pub publishes explorable explanations that are really great.
Easier sharing of deep learning models and demos
- Replicate “makes it easy to share a running machine learning model”
- Easily try out deep learning models from your browser
- The demos link to papers/code on GitHub, if you want to dig in and see how something works
- The models run in containers built by
cog, “containers for machine learning.” It’s an open-source tool for putting models into reproducible Docker containers.
Collaborate with Domain Experts
Machine Learning can be powerful, but it is not magic.
Whenever you apply Machine Learning to solve a problem, you are going to be working in some specific problem domain. To get good results, you or your team will need “substantive expertise” (to re-use a phrase from earlier), which is related to “domain knowledge.” Learn what you can, for yourself… But you should also collaborate with experts. You’ll have better results if you collaborate with subject-matter experts and domain experts.
Machine Learning and User Experience (UX)
I couldn’t say it better:
Machine learning won’t figure out what problems to solve. If you aren’t aligned with a human need, you’re just going to build a very powerful system to address a very small—or perhaps nonexistent—problem.
That quote is from “The UX of AI” by Josh Lovejoy. In other words, You Are Not The User. Suggested reading: Martin Zinkevich’s “Rules of ML Engineering”, Rule #23: “You are not a typical end user”
Here are some useful links regarding Big Data and ML.* [10 things statistics taught us about big data analysis](https://www.kdnuggets.com/2015/02/10-things-statistics-big-data-analysis.html) (and some more food for thought: ["What Statisticians think about Data Scientists"](https://www.datasciencecentral.com/profiles/blogs/what-statisticians-think-about-data-scientists)) * ["Talking Machines" #12](https://www.thetalkingmachines.com/episodes/economic-impact-machine-learning-and-using-kernel-trick-big-data): Interviews Prof. Andrew Ng (from [his course, which has its own module on big data](https://www.coursera.org/learn/machine-learning)); this episode covers some problems relevant to _high-dimensional_ data * ["Talking Machines" #15: "Really Really Big Data and Machine Learning in Business"](https://www.thetalkingmachines.com/episodes/really-really-big-data-and-machine-learning-business) * [0xnr/awesome-bigdata](https://github.com/0xnr/awesome-bigdata) See also: [the MLOps section!](#production-deployment-mlops)
If you are working with data-intensive applications at all, I’ll recommend this book:
- Designing Data-Intensive Applications by Martin Kleppman. (You can start reading it online, free, via Safari Books.) It’s not specific to Machine Learning, but you can bridge that gap yourself.
More Data Science materials
Here are some additional Data Science resources:
- Python Data Science Handbook, as Jupyter Notebooks
- Accessible data science book, no coding experience required: Data Smart by John Foreman
- Data Science Workflow: Overview and Challenges (read the article and also the comment by Joseph McCarthy)
Aside: Bayesian Statistics and Machine Learning
From the “Bayesian Machine Learning” overview on Metacademy:
… Bayesian ideas have had a big impact in machine learning in the past 20 years or so because of the flexibility they provide in building structured models of real world phenomena. Algorithmic advances and increasing computational resources have made it possible to fit rich, highly structured models which were previously considered intractable.
Here are some awesome resources for learning Bayesian methods.* The **free book** _[Probabilistic Programming and Bayesian Methods for Hackers](http://camdavidsonpilon.github.io/Probabilistic-Programming-and-Bayesian-Methods-for-Hackers/)_. Made with a "computation/understanding-first, mathematics-second point of view." Uses [PyMC](https://github.com/pymc-devs/pymc). It's available in print too! * Like learning by playing? Me too. Try [19 Questions](https://github.com/fulldecent/19-questions), "a machine learning game which asks you questions and guesses an object you are thinking about," and **explains which Bayesian statistics techniques it's using!** * [_Time Series Forecasting with Bayesian Modeling by Michael Grogan_](https://www.manning.com/liveprojectseries/time-series-forecasting-with-bayesian-modeling), a 5-project series - paid but the first project is free. * [Bayesian Modelling in Python](https://github.com/markdregan/Bayesian-Modelling-in-Python). Uses [PyMC](https://github.com/pymc-devs/pymc) as well.

Finding Open-Source Libraries
- Bookmark awesome-machine-learning, a curated list of awesome Machine Learning libraries and software.
- Bookmark Pythonidae, a curated list of awesome libraries and software in the Python language - with a section on Machine Learning.
- For Machine-Learning libraries that might not be on PyPI, GitHub, etc., there’s MLOSS (Machine Learning Open Source Software). Seems to feature many academic libraries.
- Julia: Julia.jl, a curated list of awesome libraries and software in the Julia language - with a section on Machine Learning.
Natural Language Processing (NLP)
This is just a small
- spaCy: Industrial-strength NLP - “spaCy is a library for advanced Natural Language Processing in Python and Cython.”
- There are lots of NLP-related links in awesome-machine-learning
These next two links are not related to ML. But since you’re here, I have a hunch you might find them interesting too:
- Maggie Appleton’s “A Brief History & Ethos of the Digital Garden”
- Shawn Wang’s “Digital Garden Terms of Service”
More ways to “Dive into Machine Learning”
Here are some other guides to learning Machine Learning. They can be alternatives or supplements to this guide.
- Example Machine Learning notebook, exercise, and guide by Dr. Randal S. Olson. Mentioned in Notebooks section as well, but it has a similar goal to this guide (introduce you, and show you where to go next). Rich “Further Reading” section.
- Courses by cloud vendors. These are usually high quality content but steer you heavily to use vendor-specific tools/services. I encourage you to “make the most” of the resources that they make freely available. To avoid getting locked into vendor specifics, just make sure you’re learning from other resources as well.
- Machine Learning for Developers is good for people who are more familiar with Java or Scala than Python.
- ageron/handson-ml2 aka Hands-On Machine Learning with Scikit-Learn, Keras and TensorFlow by Aurélien Geron
- rasbt/python-machine-learning-book-3rd-edition aka Python Machine Learning: Machine Learning and Deep Learning with Python, scikit-learn, and TensorFlow 2 by Sebastian Raschka and Vahid Mirjalili
- Machine Learning for Software Engineers, by Nam Vu. In their words, it’s a “top-down and results-first approach designed for software engineers.” Definitely bookmark and use it, as well - it can answer lots of questions and connect you with great resources.
