About this course
Supervised learning is the part of machine learning where the answer is already known for your training rows, and the whole job is generalising past them. Every algorithm here is a different bet about what structure the data has — a straight line, a nearest neighbour, a set of splits, a maximum-margin boundary — and interviews test whether you know which bet fits which situation, and what each one costs you.
What it covers
Ten topics: supervised learning foundations and the generalisation goal, linear regression with its assumptions and regularised variants, logistic regression and interpretation, k-nearest neighbours, Naive Bayes, decision trees and overfitting control, support vector machines and the kernel trick, multi-class and multi-label strategies, probability calibration, and a closing mastery topic on algorithm comparisons and when to use what.
Who this is for
Anyone preparing for data-science or ML interviews who can fit a model but would hesitate if asked why logistic regression beats a tree on a small, linearly separable dataset — or what calibration is for. It assumes basic probability and comfort reading a formula. Deep learning is out of scope.
Where this sits in the Machine Learning series
Machine Learning: Foundations covers framing, data preparation and evaluation discipline. Supervised Mastery goes deep on the labelled-data algorithms. Unsupervised Mastery covers clustering, dimensionality reduction and anomaly detection. Ensemble Methods & Mastery covers bagging, boosting and stacking. Foundations first, then any of the other three in whatever order your work or interviews demand.
How MCQ practice works on Abekus
The course is organised as topics, subtopics, and individual lessons. Each lesson pairs a short set of explanation cards with practice questions written for that lesson, so the questions test the idea you just read rather than a general survey. Wrong answers come with a worked explanation, and the AI guide surfaces the mistakes you keep repeating.
Machine Learning
The core Machine Learning track on Abekus — four MCQ-driven courses, ~5,800+ practice questions, ~65 hours total. Covers ML Foundations (supervised, unsupervised, evaluation, feature engineering, and optimization in one survey), Supervised Learning Mastery (deep dive into regression, classification, trees, and SVMs), Unsupervised Learning and Clustering (clustering, dimensionality reduction, and anomaly detection at depth), and Ensembles and Boosting (Random Forests, AdaBoost, XGBoost, LightGBM, and CatBoost). Built for placement candidates, developers switching into ML or data science roles, and engineers who want systematic conceptual mastery before moving to deep learning. Modules can be taken standalone, but the intended order is Foundations → Supervised → Unsupervised → Ensembles. Finishing all four unlocks the series certificate. Basic algebra and probability helps. No prior ML knowledge required to start Module 1.
