Softmax - What is the Temperature of an AI??

One of the most important parameters of AI models like the one behind ChatGPT is temperature, but how can AI have a temperature and what is it good for? While we pursue this question we uncover a beautiful connection between machine learning and statistical thermodynamics.

When I first heard about thermodynamics and statistical mechanics I thought that this had to be the most boring part of physics. I mean.... statistics!? Not clear cut facts about the fundamentals of reality? Thermodynamics also seemed to be only about the thing that made steam engines possible and perhaps make chemists happy when they saw a liquid transforming into a solid.

But as I learned more about both topics I became amazed by the kind of worldview it gets you into. I now see these as the most philosophically stimulating parts of physics. You get to understand the nature of information, energy and entropy so deeply. You see thermodynamics playing a role in each and every aspect of reality, in each process, from darwinian natural selection to the stock market, from AI to card games, from crystal formation to the emergence of design in ant colonies. You start to see the Milky Way as a gas made of stars instead of atoms, with a specific temperature and processes kicking the gas out of equilibrium. You see crowds in metal concerts as making phase transitions in moshpits, and you start to see the relevance in patterns like flocks of birds or magnetization in a solid. It's crazy how little expectations we all have around these topics before we get to learn about them.

Very nice video. I hope this chanel gets bigger and bigger, and in the end makes people aware of the profund consequences of Democritus and Lucretius ideas that everything and every process is explainable by simple mindless interacting atoms (marbles) in the void.

5:20 3 years in a data science degree mindlessly using softmax and I finally understand the intuition behind it today

This channel is seriously underrated!

Keep up the great work :)

This was a VERY GOOD explanation of temperature and the visuals helped clarify the concept even more. Bringing in concepts from other domains and creating those analogies was the cherry on top!

[AtPrEd]

What a great showcase, understood it in the first watch, great work and thanks for the video 👍

[brunabuffara]

Ohh, that was GREAT! And very ... straightforward lol

[mateuszpiechowiak]

This is an amazing explanation. Great value. Thank you so much!

Your comparision of the Boltzmann distribution and the Softmax was like flipping a switch in my brain! It was so satisfying to finally understand what the Boltzmann distribution really is saying, now that I already have a strong grasp on what Softmax does.

Super clean video and explanation! Clear, satisfying to watch, just good. Looking forward to more

Glad to see you posting again! :) Great video

With my temperature set to 0 it is inevitable to praise you for this W O N D E R F U L explanation!

[Geogeorgefrommelbourne]

One of the best AI related videos out there

[LF]

Wow! Amazing video making surprising connections and explaining them brilliantly! Again!
Love it!

[voidzircon]

Thanks for an easy to understand explanation. Very helpful!

Keep producing such awesome content... Your channel is an absolute gem of a channel.❤

[maj]

I am surprised this channel is not famous. My friend, you are doing an excellent work. Keep nerding like we all do :)

[yannickkohl]

Still an incredibly underwatched channel. Thank you for making these videos!

[robocop]

I don't usually comment on videos, but man.. the visualizations made it so much easier to understand the concept. Thanks!

[sajandumas-havenel]

Very good, thank you for providing correct information!
