machine studying engineers are presently the highest-paid tech professionals within the UK?
In keeping with Levels.fyi, the common wage is sort of £100k — larger than software program engineers, AI engineers, and knowledge scientists.
Nevertheless it’s not simply in regards to the paycheque.
As a machine studying engineer, you get to deal with fascinating issues, experiment with cutting-edge instruments, and really positively have an effect on the world.
I can inform you from first hand expertise — it’s one of the crucial thrilling and fulfilling jobs.
So on this article, I’ll provide you with a transparent and easy studying roadmap to turning into a machine studying engineer, together with the most effective assets.
Let’s get into it!
Maths and Statistics
I’ve stated it time and time once more, however maths and statistics are by far a very powerful issues you need to be taught if you need a profession in machine studying or in knowledge as a complete.
Applied sciences come and go, assume blockchain and AI, however maths stays a elementary staple all through the centuries.
Luckily, you don’t should be some maths genius to work in machine studying, I can wholeheartedly verify this from first-hand expertise.
The extent of maths required is equal is a lot of the stuff you get taught in your last years of highschool and first 12 months or two of an undergraduate STEM diploma.
Typically, there are three areas of maths you want to research:
- Linear Algebra — To find out about matrices, eigenvalues and vectors. These are used in all places in areas like principal element evaluation (PCA), TensorFlow, I imply, even a dataframe is a matrix!
- Calculus — To find out about differentiation, which is how algorithms like gradient descent and backpropagation work underneath the hood. These are actually used inside each machine studying algorithm for coaching and studying.
- Statistics — To grasp chance, distributions, Bayesian statistics, the central restrict theorem and most chance estimation. Statistics is probably the most useful one out of the three, and I’d focus most of my consideration right here.

How to Learn the Math Needed for Machine Learning
Python
Python is the lingua franca in relation to machine studying; neglect about R, be taught Python. (Sorry to my R lovers on the market!)
A standard theme I’ve noticed amongst my teaching shoppers and novices I’ve spoken to is that they’re looking for the “greatest” course to be taught Python.
I’ll reiterate this level once more, the “greatest” doesn’t exist, so cease searching for it; it’s merely a type of procrastination. Any fashionable introduction to Python course will work, as they’ll train you the very same issues.
Anyway, the primary stuff you wish to be taught are:
- Native knowledge constructions (dicts, tuples, checklist)
- For and whereas loops
- If-else conditional statements
- Features and courses
- Frequent libraries
- Design patterns
You additionally wish to be taught fashionable machine studying packages, reminiscent of:
- NumPy — Numerical computing for arrays.

SQL
As a machine studying engineer, you’ll be spending an inexpensive period of time working in SQL when attempting to create datasets or do some function engineering.
I most likely work in SQL round 30-40% of my time as a machine studying engineer. That’s quite a bit, so that you positively should be properly versed in it, greater than you assume.
The issues to be taught are:
- SELECT * FROM, AS
- ALTER, INSERT, CREATE, UPDATE, DELETE
- GROUP BY, ORDER BY
- WHERE, AND, OR, BETWEEN, IN, HAVING
- AVG, COUNT, MIN, MAX, SUM
- FULL JOIN, LEFT JOIN, RIGHT JOIN, INNER JOIN, UNION
- CASE, IFF
- DATEADD, DATEDIFF, DATEPART
- PARTITION BY, QUALIFY, ROW()
Assets:
There are lots of free assets for SQL, so I don’t advocate you hassle spending cash on a course, until you actually wish to. You can even at all times use ChatGPT as properly!
Machine Studying
To everybody’s shock, we have to be taught machine studying to be a machine studying engineer!
That is arguably probably the most enjoyable a part of the roadmap and what most individuals get into this area for. I get it, as a result of it was the rationale I made a decision to work in machine studying!
I’d be mendacity if I stated studying these algorithms was at all times enjoyable. It does require a little bit of psychological time and effort to completely grasp all of the ideas, however finally, issues will click on, and will probably be properly value it.
The important thing algorithms and ideas you want are:
- Linear, logistic and polynomial regression.
- Generalised linear fashions and generalised additive fashions.
- Resolution timber, random forests and gradient-boosted timber.
- Assist vector machines.
- Ok-means and Ok-nearest neighbour clustering.
- Function engineering, notably how you can cope with categorical options.
- Analysis metrics for various kinds of issues.
- Regularisation, bias vs variance tradeoff and cross-validation.
- Gradient descent and backpropagation.
Assets:
- Machine Learning Specialisation by Andrew Ng — This the primary ML course I took, and I believe it’s most likely the most effective one on the market. Andrew is actually the most effective trainer, this course is one everybody ought to take in my view.
- The Hundred-Page ML Book — Concise with sensible insights into constructing ML fashions and the core idea behind them. Beautiful nighttime studying.
- Hands-On ML with Scikit-Learn, Keras, and TensorFlow — If I needed to give just one ebook to be taught machine studying, this is able to be it! This ebook is the GOAT and covers actually each subject you would want as an entry/mid-level machine studying engineer.
Deep Studying
Being trustworthy, the elemental machine studying algorithms will cowl the vast majority of fashions you’ll construct in your profession.
I nonetheless use common regression fashions more often than not!
Deep studying is useful in situations reminiscent of pure language processing and laptop imaginative and prescient, however its use in my each day work is minimal past these areas.
Nonetheless, take this with a pinch of salt, provided that I specialize in time sequence forecasting and optimisation issues, that are notoriously tough for deep studying to carry out properly in.
With all that stated, deep studying is an space all machine studying engineers ought to be considerably conscious of as it’s a core a part of the sphere.
The areas you wish to research are:
- Neural Networks — The algorithm that put machine studying on the map. I’m certain a lot of you will have heard of this algorithm.
- Convolutional Neural Networks — These are used for laptop imaginative and prescient and picture detection. The important thing distinction is that they use the convolution operation to “pre-select” data earlier than passing it into an everyday neural community.
- Recurrent Neural Networks — A little bit bit out of date now, however have been the unique deep studying algorithm for sequence fashions like time sequence and pure language. The preferred one you will have heard of is sequence to sequence modelling.
- Transformers — The present state-of-the-art mannequin that’s behind all of the AI hype and development. This comes from the well-known paper “Attention Is All You Need”, that I extremely advocate you learn!

MLOps
A mannequin in a Jupyter Pocket book has actually no enterprise worth.
It’s a lot better to have one thing in manufacturing, making subpar selections that profit the enterprise, as a substitute of a flashy neural community in a pocket book doing nothing however has unreal accuracy.
Subsequently, should you truly wish to be a sound machine studying engineer, you want to have the ability to deploy your fashions so that you truly profit the corporate from a monetary perspective.
To do that, you want to be taught the next:
- Cloud — Be taught cloud applied sciences like AWS, GCP or Azure. All of the machine studying fashions I’ve labored on have been deployed on the cloud, and that is solely going to extend sooner or later. AWS is the preferred, so I like to recommend that’s the one you be taught.
- Containerisation — Be taught Docker and Kubernetes; that is crucial for operating your fashions within the cloud.
- Model Management — Be taught Git and Github, there isn’t any method round it. That is how all software program is constructed.
