A 2022 student post on Cornell's Networks course blog explaining Bayes' theorem and how it is used to update probabilities in AI systems such as spam filters and classifiers. Written by a student, not course staff.
Personal site of A. Feder Cooper, a researcher working on the intersection of machine learning and law, including work on copyright and generative AI, data privacy and ML systems. Lists publications, talks and writing.
A step-by-step tutorial on building a simple AI "world model" that predicts what happens next in an environment.
Why I recommend it: Hands-on and free; assumes some Python. Written by a single contributor, so check the code as you go.
Hands-on tutorial (Sept. 2026) showing how to spot when the text data a live AI system sees starts to shift, using a domain classifier and centroid distance.
Why I recommend it: Free tutorial. Assumes you know Python and basic machine learning.
Jason Brownlee's long-running tutorial site: hundreds of free, step-by-step machine learning walkthroughs in Python, organised into 'start here' guides by topic — getting set up, understanding algorithms, your first complete project, your first neural network, time series forecasting. Each tutorial is written to get you to a working result rather than a theory exam.
Why I recommend it: The tutorials and the 'start here' guides are free to read with no account. The site's business is paid ebooks, and the free ebook offer costs you an email address and an ongoing email course, so expect the marketing. A fair criticism to know going in: the tutorials are recipe-shaped, which gets you running code fast but can leave the why thin — pair them with something that explains the ideas.
The free research library and blog of Snorkel AI, the company spun out of Stanford's Snorkel project on programmatic labelling. The papers and posts explain how training data for AI models is actually built — labelling, evaluation sets, and the 'environments' used to train agents. Useful if you want to understand the unglamorous data work behind model quality, which is where a lot of the real jobs are.
Why I recommend it: Research and blog posts are free to read with no signup. Read it for the how, not the verdict: Snorkel sells data services to frontier AI labs, so posts arguing that better data beats bigger models are also a sales case. Everything else on the site is a paid enterprise product — 'request dataset samples' means a sales call.
Long-running free publication on data science, machine learning and AI, mixing daily tutorials with roundups of tools and techniques. Free to read, supported by ads and affiliate links.
Why I recommend it: Strongest on hands-on tutorials, weakest on product roundups — several posts carry affiliate links to courses, so treat recommendations as suggestions rather than independent verdicts.
Free programs for undergraduate students pursuing tech careers, with a current focus on AI, data science and machine learning pathways. Includes fellowships and work-based learning run with university and industry partners.
Why I recommend it: No cost to students, but programs are application-based and tied to specific universities and cohort dates. Check the programs page for who is eligible before you plan around it.
A platform for data science competitions, public datasets, and collaborative notebooks to practice machine learning.
Why I recommend it: Competitions, public datasets, and notebooks are free; heavy compute or private datasets need a paid plan.
