Thank you for the comment.

My target audience is people who would like to understand concepts in machine learning but want the concepts to be individually packaged as one concept per video, compared to other ML youtubers or lectures which may cover many topics in one video and can feel overwhelming. Additionally, my focus is to be as clear as possible, provide an example in certain cases, but be more math oriented as I previously mentioned. I do wish to build an audience in the future, but the quality of my videos and the Youtube channel being important to my learning process is primary. One reason for wanting to build an audience is to ensure that the videos I make are actually useful for others as well. That's why I asked for feedback.

I further agree that I need a better introduction, maybe an example of where and how this concept can be used, and why we need it. I will keep this in mind for future videos. Thanks for your feedback!
