Overview
Data science is data, math, statistics and machine learning, working as one.
A three-hour survey of data science in six modules. It defines the field and its applications in healthcare, retail, finance and energy, then builds the mathematics: calculus, optimization algorithms and linear algebra.
Statistics, from probability and hypothesis tests to the Central Limit Theorem, comes next, then the core machine learning methods and their metrics, A/B testing, and an introduction to NLP and language models.

What you’ll learn
Learn all the way down.
Learn all the way down.
Perform when it matters.
The math behind the models
Refresh algebra and calculus, study gradients and optimizers such as SGD and RMSprop, and work through the linear algebra that ML uses.
Statistics for decisions
Move from probability and Bayes’ rule to distributions, hypothesis tests, p-values and the Central Limit Theorem.
Models, experiments and language
Survey supervised and ensemble methods, design and analyze A/B tests in Python, and meet NLP from TF-IDF to BERT and GPT.
Course outline
Six modules, from what the field is
Six modules, from what the field is
to A/B tests and language models.
Define data science as data, math, statistics and machine learning, see how it creates value, and look at applications and case studies across industries.
Look at what to expect from the work, the common entry roles and career trajectories, and how data science leads on to AI and machine learning.
Refresh algebra, trigonometry and geometry, then cover derivatives, gradients, optimization algorithms and linear algebra from vectors to QR decomposition.
Cover probability and Bayes’ rule, descriptive statistics and key distributions, then regression, hypothesis tests, p-values and the Central Limit Theorem.
Compare supervised and unsupervised learning, then work through regression, KNN, LDA, trees and ensembles, resampling, and the metrics that score them.
Design and analyze A/B tests, with power analysis and sample sizes, then meet NLP: tokenization, TF-IDF, word embeddings and an overview of LLMs.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
