Right, let’s now get into the roadmap!
Maths
I’d argue that solid mathematics skills are probably the most essential for any tech professional, especially if you are working with AI/ML.
You need a good grounding to understand how AI and ML models work under the hood. This will help you better debug them and develop intuition about how to work with them.
Don’t get me wrong; you don’t need a PhD in quantum physics, but you should be knowledgeable in the following three areas.
- Linear Algebra — to understand how matrices, eigenvalues and vectors work, which are used everywhere in AI and machine learning.
- Calculus — to understand how AI actually learns using algorithms like gradient descent and backpropagation that utilise differentiation and integration.
- Statistics — to understand the probabilistic nature of machine learning models through learning probability distributions, statistical inference and Bayesian statistics.
Resources:
This is pretty much all you need; if anything, it’s slightly overkill in some aspects!
Timeline: Depending on background, this should take you a couple/few months to get up to speed.
I have in-depth breakdowns of the maths you need for Data Science, which is equally relevant right here for AI/ML.
Python

Machine studying
That is the place the enjoyable begins!
The earlier 4 steps concerned getting your basis able to sort out machine studying.
Usually, machine studying falls into two classes:
- Supervised studying — the place we now have goal labels to coach the mannequin.
- Unsupervised studying — when there are not any goal labels.
The diagram under illustrates this cut up and a few algorithms in every class.
The important thing algorithms and ideas it’s best to be taught are:
- Linear, logistic and polynomial regression.
