wait are you telling me there is an arbitrary hexagonal grid of points in my room where specific cells light up the most?
-
I'm a postdoc in the intersection of neuroscience and AI, specifically about the generalization subject, and I just want to say that you are doing an amazing job communicating scientific discoveries, which is specially hard for things that happen in the brain. Huge congrats.
-
Amazing video! Neuroscience for those of us without a PhD -- explained as simply as possible but no simpler. It's so fascinating to me how complicated the brain is, and yet it has these basic building block structures that we can actually make sense of.
-
This videos, apart from having concise and beautiful animation, really get to the core idea of explaining the subject. Keep going, you are doing an amazing job at neuroscience divulgation
-
Somehow it's all drastically obvious, since you're explaining the simplest way to learn, yet simultaneously it's very fascinating to learn these basic methods.
-
AI/HPC researcher here. I just love how you integrate neuroscience, math, physics and computing in your stubs ❤ Greetings from Brazil
-
I've been teaching this subject matter for three years, and you've done a great job of simplifying the subject.
-
thank you for taking your viewer's suggestions into account! I especially appreciated the explanation of factorization
-
Excellent editing skills, second only to your depth and exactitude. I am inspired to delve deeper into these topics and find the commonality between this and contemporary QM
-
Thank you so much for all the effort to make these videos, I found your channel yesterday and is amazing, it's one of the best I've seen on YouTube, especially this video. I loved the way you explain all these abstract mathematical concepts in such a clear way. Greetings from Chile!
-
This video is amazingly clean and beautifully put together/choerent. I am appalled this video (and the rest of your videos) don't have millions of views (yet). Even if I have barely any hope of understanding most of what was said in this video, you came as close as possible to making me I think I do. And either way, if this entire video was in a completely foreign language with no subtitles, I would still have watched the whole thing for the visuals alone. Fantastic
-
This content is so good I draw mind maps and summarise on a massive whiteboard while I listen to you. It’s great content, thank you.
-
Artem, mate, your videos are just amazing. You are the future of education. Keep up the stunning work!
-
The production quality on this video is incredible. Amazing work
-
This is really interesting when applying it to sport. It may explain "home ground advantage", and certain training strategies that could aid with spatial awareness despite sporting locations.
-
3:14 -- Amazing transition: visuals + voice + story flow work perfectly!
-
Your visual and verbal explanatory ability are absolutely masterful.
-
Yet another outstanding video. Thank you for making such high quality content. I look forward to the second part discussing the Tolman Eichenbaum Machine. It is especially interesting, considering they were able to replicate the results by modifying a transformer, the backbone architecture to popular LLMs such as ChatGPT. Again thanks for providing the highest quality computational neuroscience content on youtube

Artem, you absolutely set the bar for sci-comm on YouTube. I truly haven't seen anyone better. Thank you ❤
