There are many online courses on machine learning. I would suggest the following:

1- MIT Introduction to Deep Learning

6.S191 Link 10 videos, each around 50mins.

2- Stanford CS229: Machine Learning by Andrew Ng

Autumn 2018 Link. A similiar one is avaiable on Coursera.

3- Hugging Face Course link 80 videos and material. A more practical aspect of LLM.

Depending on your goal, the following courses are useful:

• Machine Learning Undergraduate Course by Kasper Green Larsen (Aarhus University) link, 59 Videos. A more mathematical course.

• Stanford CS224W: Machine Learning with Graphs by Jure Leskovec Link 60 videos.
