16 Options to Get Started and Make Progress in Machine Learning

Last Updated on September 29, 2016

You want to learn machine learning or data science.

You might want a job or the opportunity to get a job in machine learning or data science. Alternatively, you might be a student or in a data role and looking to accelerate your learning in the area.

If you think your only options are to get a PhD or to read an academic textbook, think again. This post is for you.

You have a lot of options when it comes to training and educational material. So many that you should take your time, make a short list of some options and even try a few before settling in.

In this post you will discover the vast number of options available to you and have enough information to choose a direction (or two) and take that next step in your journey.

Where You Fit, Getting Ready

You are looking for educational training in machine learning or data science.

You may have specific subject areas you want to get better at or know more about. What are they? Right them down.

You may have a preference for a specific learning style, like in-person, audio, video, textual tutorials books. What are your preferences? Write them down.

You have specific reason you want to learn machine learning or data science. It may be as described above, a desire or opportunity for a job, desire to learn more or faster for an existing role, or for general interest and opportunity. What is your one reason? Write it down.

Note all three points in a comment if you like. You’re not alone.

Short-List of Machine Learning Training Options

Let’s not dance around, here is a short list of your options to get started and make progress in machine learning.

  • University Degree
    • PhD Degree (research)
    • Masters Degree (by research)
    • Masters Degree (by coursework)
    • Undergraduate Degree
  • In-Person Course
    • Training Courses and Workshops
    • Bootcamp
  • Online Course
    • MOOC
    • Paid Courses
    • Self-Study University Course Material
  • Books
    • Academic (textbooks)
    • Professional (O’Reilly)
    • Practical Books (Packt)
  • Free Content Online
    • Academic (papers, blogs)
    • Industrial (blogs, youtube, communities)
  • Tools and Libraries
  • Competitions

You can see that the top of the list is heavy in supervised and structured academic options and that bottom of the list is focused on less-structured self-study options. Another axis that you could consider options that is less stratified is that of academic versus industrial focus in the materials.

I thought about these axes for a while, I think they are a useful aid. I assigned scores to each option along these axis of Supervised to Unsupervised (self-study) and Academic to Industrial and created a little scatter plot. It is not a perfect breakdown, material can be self-study, unsupervised but still highly structured. A PhD is highly academic, but generally a lot less supervised than most other degrees (at least under the Australian/British system that I studied under). The supervised/unsupervised dichotomy does not capture enough, but it’s a starting point.

Let me know in the comments if this helped.

Options Available to You In Machine Learning

We’ll spend the rest of the post diving into each of these in turn, what they offer, who they’re suited to and specific examples you can follow-up with.

University Degree

A university degree provides a highly structured, mostly academic, mostly theoretical introduction to a topic. You probably know what a degree is.

Undergraduate degrees and some masters programs are by course work, and U.S. PhD’s also have a course work element. Some honors, masters and PhD programs have a research component, more so as you step deeper into the system.

Great coursework subjects are highly structured, designed by an expert in the field to give you the best introduction in the subject matter. Great research programs give you an apprenticeship into the scientific method and research methods.

Degrees are also expensive, take a long time, designed for the average student and teach older even out-dated information.

A degree can be the right move if you have a lot of time, money and don’t want to design your own study programs at all.

I’m not an expert in the degree programs offered around the country or around the world, but there is a lot of information available. For example, take a look at this healthy list of masters programs in machine learning and data science.

The degree is the starting point, not the end point. It’s a slow burn on a subject that gets you to a place where you are ready to begin practicing. It’s also the one time when you have the time to go deep into a subject with little other responsibilities.

Some people that ask for advice believe (deeply) that they cannot get into machine learning without going back to university for a handful of years and study a formal degree.

You do not need a degree to learn and practice machine learning. In fact, you don’t need a degree if you want to explore research in machine learning.

In-Person Courses

There are options that are not nearly as long and expensive as degree programs, but offer highly structured in-person training, and they are highly industry focused rather than academic.

Options include short training courses and bootcamps.

Training Courses and Workshops

You can take a short training course on a specific machine learning topic. The course will be highly targeted on a specific technique or a specific tool.

IT training companies have been around forever and have stared offering training around specific data science and machine learning topics.

There are also new companies that only target this type of training. For example, Persontyle is an example company that offers a vast array of short (1, 2, 3 and 5-day) courses on specific courses like Hadoop for Data Scientists and Introduction to Data Science Using R.

Finally, universities may offer short training courses for industry, local meet-up groups often offer training, and academic conference often have workshops in modern methods deigned for industry and graduate students.

Bootcamps

A popular approach are data science and machine learning boot camps. These are 6-12 week programs that professionals attend in person and learn applied skills. Often there is a hiring day at the end of the program to match employers with course participants.

Zipfian Academy is a popular example that offers a 12-week full time program in dat science with modules, capstone project and hiring day. Prices are in the range of $16,000.

This is a popular area and there are a raft of competitors:

For a good round-up on machine learning and data science bootcamp programs, check out the post “Data Science Bootcamp Programs – Full Time, Part Time and Online” by Ikechukwu Okonkwo.

Online Courses

Education throughout the rest of your life will be rooted in self-study and mentorship.

There are a lot of self-study programs available and some like MOOCs are also highly structured. Most, like MOOC’s are spun out of university subject material and therefore are generally more academic focused.

Massive Open Online Course (MOOC)

This are still a very popular method for getting started in machine learning, given the success of the Stanford Machine Learning MOOC that launched Coursera.

Courses are often 10-12 weeks in length, requiring many hours per week. Many are free or offered at a small cost. The are less industry focused and more academic than bootcamps, but offer training that was only ever accessible within a university graduate program. They often include lecture videos, homework, assignments and a community form to discuss the material with fellow students.

Courses operate in batch, to ensure a cohort have support in the form of classmates on their path through the program.

Popular examples from Coursera include:

A popular MOOC from edX is Learning From Data.

Some MOOC courses are paid (like the John Hopkins Data Science MOOC). There are also shorter length paid courses availabe. Some are spun out of university subjects (like these MIT courses) and workshops and others are completely standalone.

Udacity offers a number of paid courses, such as:

Udemy is another company that offers paid course, I’ve covered their offerings before in a post “Machine Learning Courses on Udemy“. Two highlights are:

Linda also offers lots of short videos on machine learning and data science, for example checkout their playlist titled “Data Science Basics” if you have a linda account.

Variations on MOOCs

There are also variations on MOOCs.

For example, you can get free access to the course materials for undergraduate and graduate machine learning university courses and study the course yourself. Some have lecture videos available as well.

Some great examples include:

There are also open data science and machine learning curriculum that you can study.

Books

There are many amazing books on machine learning and data science, but you are probably reading the wrong books. This can throw you off track and crush your motivation.

I like to break the books down into three categories: academic, professional, practical.

Academic Books

These are the textbooks used in graduate and undergraduate programs.

You do not want to read these books until you are ready. Until you have been practicing for a while, have some confidence with some algorithms and tools and are ready to dig deeper into why the algorithms work rather than how.

Springer books come to mind readily, but there are many other publishers like The MIT Press, Cambridge University Press and more.

Examples of good textbooks are:

Textbooks are academic and require a discipline to read, to take notes, to do the exercises to dive into the references. The work is all on you. Textbooks are best used as a reference on select topics when needed.

Professional Books

These are the books you read if you are a software engineer or practicing data scientist and are looking to add more structure to your work or improve in a specific area.

I think of O’Reilly as a publisher in this area, who have been very bullish on “data” books on data science and machine learning.

Some popular professional O’Reilly books include:

Not to mention the technology specific books on Hadoop, R, Python, and friends.

O’Reilly also have white papers and reports that seem to be expanded versions of blog posts. I’ve read a few and they are so-so. Some examples include:

O’Reilly also have a conference on all things data called Strata. You see what I mean when I say bullish. Data is the intel inside and Tim O’Reilly has made “data” an agenda item.

Springer are also edging into this area with two great books:

I love these two books because they are a slightly more academic than the O’Reilly books, but a hell of a lot more accessible than Springer’s textbooks in the area.

I also put Data Mining: Practical Machine Learning Tools and Techniques and Machine Learning in Action in this camp.

Practical Books

These are books that are tutorials and recipes. Some of O’Reilly books fall into this area, such as their cookbooks and nutshell books.

I think of Packt Publishing in this area. The books are generally not as complete as the books listed above, but they are focused on how to do specific things.

Some popular examples include:

Very actionable, industry focused and generally cheaper.

I love books and I read a lot, take a look at some of my posts on practical books:

Free Online Content

There is a lot of free content. Some of it is amazing, and a lot of it is dross.

The content is generally unstructured, or structured within the content, but no cohesive grand plan that links the content together. No study plan. You must construct your own study plan.

You can use this content to learn what you want, when you want. Blog posts are typically too short to dive deeply into a topic, you often need to jump into a book or course to get depth.

I think of free content in two classes: academic material such as papers and professional materials such as blog posts and youtube.

Academic Materials

Academic materials include papers, articles, technical reports and theses. The onus is on you to extract what you are looking for, such as the details of an obscure algorithm or ideas on feature engineering for a specific data type.

Google Scholar is your friend when searching for papers.

There are some academic blogs and these too fall into this category.

The Google research blog fits into this area, Alexander Smola’s blog, Mark Reid’s blog and academics making things happen in industry such as John Langford’s blog and many many others

Professional Materials

Professional materials are created by those learning or practicing machine learning. They may be students, programmers or data scientists. They may be creating materials to teach, to share or to better understand the material.

YouTube channels also fit into this and there are some excellent ones (and we’re not limited to university lectures)

The Mathematical Monk has a great channel on machine learning. You can get a lot out of recorded talks from industry conferences and meetups such as Pycon 2014 (search for machine learning related videos). Google tech talks are great (again, search for topics on machine learning). You can get a lot of industry news from O’Reilly Strata videos, such as those from the 2014 meeting.

Tools and Libraries

I separate out tools and libraries because they are important area of machine learning education. They are the means by which you do and practice.

There are books, blogs and videos on the tools, and if you’re lucky, there are tutorials and documentation.

An important area is to study both the landscape of tools and libraries available to you and go deep into specific examples.

Generally, this is a wholly on the industrial side rather than academic and wholly self-study. There are very few courses that teach you how to get the most out of tools and libraries.

Tools I often recommend learning a lot about, depending on where you are on your journey are:

There are suits of big data infrastructure to learn about as well as niche tools for specific domains and techniques.

There are a lot of tools and libraries available and a lot of room to go wide and deep.

Machine Learning Competitions

Out on the edge you have machine learning competitions.

These require a certain level of skill in a tool, data handling and algorithm usage before you can get started, and world class expertise to do well.

You are on your own in terms of guidance, but there is community and great opportunity for learning state-of-the art algorithms and practices in a competitive environment.

The skills are you learn are applicable in industry, but real-world problems do require more from you. This area of learning is not for everyone, but does offer a lot for those it does suit.

Competitions are often held in conjunction with academic conferences, and more often are now hosted by companies such as Kaggle and TunedIt. Recent popularity has meant more companies are opening up their data to competitions so that access to varied and interesting industrial datasets is now common place.

Summary

We have covered a lot of ground in this post and you have discovered that there are a lot more options available to you than you probably first think.

I want to see comments like “I need a degree” and “there are no good resources” go away. There have never been more options and more resources available to start and practice machine learning, both on the academic side and the industrial side, both in a highly structured and supervised environment and self-study.
