Here's a look at the different courses provided by Harvard.
Data science: Building machine learning Models
This course explains basic machine learning concepts and methods. It covers common algorithms, principal component analysis, and regularisation.
Students will reportedly learn how to use training data to find patterns and make predictions. It also explains how to train models and test them on new data.
The course also includes building a movie recommendation system and introduces issues like overfitting, along with methods such as cross-validation to handle it.
Machine learning and AI with Python
Starting with decision trees as the basic algorithm, this course introduces machine learning using Python.
Methods like bagging, random forests, and gradient boosting, are covered in this course. Students will also reportedly work with sample datasets to understand how models are built, tested, and evaluated, as per reports.
The course also explains how to improve predictions, avoid overfitting, reduce bias, and analyse results while updating models with new data and conditions.
CS 50’s introduction to programming with Python
This course introduces programming using Python.
This course reportedly covers reading, writing, testing, and debugging a code. Students will ralso learn about variables, data types, functions, arguments, and return values.

It also explains conditions, Boolean expressions, loops, objects, and methods. Additional topics include exceptions, file handling, and libraries. The course includes practical exercises based on real-world problems to help you practice and understand programming concepts.
Introduction to data science with Python
This course covers regression models such as linear, multilinear, and polynomial, along with classification methods like kNN and logistic regression using Python.
It uses libraries including sklearn, pandas, matplotlib, and numpy. Students are said to learn concepts like model complexity, overfitting, regularization, and evaluation. The course also explains trade-offs and uncertainty.
CS 50: Introduction to computer science
Computer science and programming basics for beginners and non-beginners is said to be introduced by this course.
languages such as C, Python, SQL, JavaScript, HTML, and CSS, will be taught to the students, and the course includes problem sets and a final project.
It is self-paced, and a certificate is awarded after completing assignments and meeting required scores.
