Physics Informed Machine Learning: High Level Overview of AI and ML in Science and Engineering

This video describes how to incorporate physics into the machine learning process. The process of machine learning is broken down into five stages: (1) formulating a problem to model, (2) collecting and curating training data to inform the model, (3) choosing an architecture with which to represent the model, (4) designing a loss function to assess the performance of the model, and (5) selecting and implementing an optimization algorithm to train the model. At each stage, we discuss how prior physical knowledge may be embedding into the process.
Physics informed machine learning is critical for many engineering applications, since many engineering systems are governed by physics and involve safety critical components. It also makes it possible to learn more from sparse and noisy data sets.

[@chri_pierma]

As a visiting Ph.D. student who is starting a research activity on optimization of PINN, I could not thank you enough for this.

[@FouziaAdjailia]

do you have any published research? I'm machine learning research in CFD as well

[@chri_pierma]

@@FouziaAdjailia nope, I just started working on SQP algorithms for neural network optimization with PDE constraints (which easily falls into the PINN category)

[@karlmaroun2389]

​@@chri_pierma SQP as in sequential quadratic programming ?

[@chri_pierma]

@@karlmaroun2389 that is correct

[@hyperduality2838]

Problem, reaction, solution (optimized predictions or syntropy) -- the Hegelian dialectic. Inputs are dual to outputs. "Always two there are" -- Yoda. Thesis is dual to anti-thesis creates the converging or syntropic thesis, synthesis -- the time independent Hegelian dialectic. Neural networks are using duality to optimize predictions -- a syntropic process, teleological. Enantiodromia is the unconscious opposite or opposame (duality) -- Carl Jung.

[@Crappylasagna]

As an undergraduate venturing into wearable robotics, this is literally a gold mine

[@GeoffryGifari]

wearable robotics? like power armor?

[@Crappylasagna]

@@GeoffryGifari Yes, thou my thesis is on enhancing athletic performance.

How is this channel not millions of subs already?

[@HarishNarayanan]

This is easily the most exciting video I have seen in so long. Looking forward to the rest of the series!

[@ajred0581]

Hi Professor Brunton, I am a high school senior, and I just want to say I love your videos! Your KZbin channel made me realize how much I want to study applied math. Thank you!

[@nias2631]

Unasked for opinion but... Go for it, I was an applied math major w/minor in physics who became fascinated by ML in 2015 after taking Andrew Ng's Coursera course. I work with ML/RL now in the space industry and am a part time PhD student. Best thing ever! These algorithms bring mathematics to life in a crazy way. Plus, the full application of mathematics is barely even scratched yet. I think in the coming years we will see this happen.

[@aninditadash3204]

Thank you for the making these videos available to everyone.

[@thoppay76]

Dear Professor Brunton. thanks a lot for putting together a lecture series on such a great topic. Very much looking forward to learn this domain.

[@lingzhu7554]

i don't want to miss any of your lectures. Thank you, professor.

[@lucascarmona1045]

Professor, I don't think I can stress this enough: thank you for all your and your team's work. As you were laying out the roadmap of what we might be seeing in the future I was getting more and more excited and just could not believe that we are getting this much.

[@loipham31]

I have special interest in the lectures by Pro. Brunton. I wish I had him taught in my education.

[@datagigs5478]

The lecture was outstanding and truly engaging. I'm eagerly anticipating the forthcoming videos in this captivating series, especially with the promise of assessing some intriguing engineering problems.

[@wadejohnson4542]

Captivating, to say the least. I am so looking forward to this lecture series. Prof. Brunton, I hope that you can deliver on your promises. I am so excited. Hoping to implement a few of the models along the way. Thank you.

[@khaldibel]

Absolutely blown away by this video! 🚀 The insights to be shared later are truly fascinating. Can't wait for the entire lecture series on Physical Informed Machine Learning. This topic is incredibly promising, and I'm eager to delve deeper into the subject. Kudos to the creator for such an engaging and informative content! 👏👏

[@jatinkm]

This is really invaluable information. Thanks for making this public. Especially when there's so little talk about it on the internet

[@qaisalzoubi308]

I love this channel , he can simplify any most complex topics .

[@arunamanipura3864]

Thanks very much Professor Brunton. Absolutely engaging lecture! I'm a novice to data science, yet you inspired me to show the potential and applications of physics informed ML. I'll definitely follow the whole series.

[@franpastor2067]

This topic looks super exciting and promising, I feel lucky for finding this video, thanks for sharing knowledge like this, professor Brunton

[@rocketmike9847]

This series will be gold

[@biswajyotikar4007]

Hello Prof.: Your lectures on PIML / PINN is too Good, awesome. I was looking for these materials for a long time as I wanted to include the knowledge of Physics to guide ML in order to produce better results.

[@dhimitriosduka607]

As someone who loves Physics and studies CS, I'm excited about this series!

[@climbscience4813]

Really looking forward to this!! I've been working on algorithms that take physical properties or measurements for about a decade during a time where machine learning wasn't as popular yet. Really, the most important part of the game was integrating as much knowledge about the physics, statistics and measurement techniques as possible into the reconstruction and apply them as boundary conditions or regularization terms into the optimization. I feel that machine learning can greatly benefit from that on the one side and on the other hand I'm stoked to see what can be done with that combination! 😃

[@cameronsmith9448]

I’m a Master’s student studying uncertainty quantification in physics informed ML models. I look forward to seeing your whole course!

[@RealUniquee]

Simply amazing! So many new concepts that I hadn't noticed as a bystander.

[@dm20422]

Outstanding, and thank you for sharing.

[@adamtaylor2142]

Steve - I can't overstate how much i have been enjoying your online courses. Will these PINNs courses include some example code?

[@learningwithandres4906]

Amazing Professor thank you!

[@nightsailor1]

Subtext here is a lesson to the young STEM persons. The Cutting Edge is alive, tempting, daring, fluid and rewarding. It is easy to field a view that the world is complete and all we need now is caretakers and accountants. Steve demonstrates here how the mind can continually be challenged for broad human benefit. Side note; A+ perfect performance students are needed but so are lessser grade students. Innovation finds improvements from every strata of contribution.

[@aditya_a]

So exciting, really looking forward to this

[@kamaljoshi9687]

[@TD-ut9ub]

Our man's been working out

[@miketaylor3947]

Is there a pointer to a description of the studio environment used to create this vid? Very professional and well-done! Sure beats a scratchy chalk board, slide projection in the background, etc!

[@adilrasheed]

Eagerly waiting Brunton. Bring it on

[@sahandsabet4728]

What a beautiful lecture Steve for 2024

I can't wait to see the model of world!👍

[@faqeerhasnain]

Love You Sir, You are an inspiration.

[@Matlockization]

I'm wonder whether AI has reached the complexity of the human brain yet. Although the human brain has well established speciality areas, so we like in hope. Although, memGPT is a huge breakthrough ! Great video once again.

[@MZgenstory]

So helpful, thanks for a good lecture 😄

[@MrMiguelChaves]

Good timing! 1 day after the "release" of Sora and V-Jepa

[@moienr4104]

I have an interview on physics-informed ML tomorrow, and I just stumbled upon this! Thank you!

[@TheAryedemented]

good luck!

[@raheelhammad8905]

@moienr4104 ... so how did it go

[@jatinkm]

Hey I wanted to know if it is a field with future scope and demand, and also what kind of qualifications are required for such jobs? Would you like to connect?

So happy to see this lecture. PINNs are the key to control and reliability in this decade. Will be exciting to implement

[@tariq3erwa]

Thank you!

[@virgenalosveinte5915]

Steve the GOAT Brunton back at it again god bless

[@mason4295]

Hi Steve is it safe to assume that this is an introduction for a new upcoming series or is this mostly an introduction to your Physics Informed Machine Learning playlist from ~2 years ago? Thank you for providing this awesome series for free. I have always been obsessed with physical science and tech and I think this field is amazing. I can't think of anything I would rather do. That being said, although I will soon graduate from a two year coding bootcamp with a focus on Python and machine learning, I am a little worried about how I could break into this field without attending a PhD or masters program and I do not have the financial resources to afford such a program. It would be great to learn what I should do to start transitioning into this field and proving my worth. This course will surely help my confidence. Thanks again.

[@Eigensteve]

Yes indeed, a new series, maybe 5-10 hours of content coming out over the next few months

[@parikshithk8289]

I'm so excited..

[@byronwatkins2565]

It seems to me that separating the symmetry from the neural network would be far more reliable. Simply including many orientations in the training is the lazy approach. Instead, concentrate on one side (e.g. the left side or the right side) and concentrate on g pointing down while training the network. Then precede the network with a symmetry varying algorithm that rotates the input by 5-10 degrees while watching the correlated output. If the subject has bilateral symmetry, then repeat the process after exchanging x-x. Then consider only the best output(s) when deciding how to classify the image.

[@davidajaba]

I love this. ❤

[@jayeifler8812]

The book wasn't free and no further links to other resources. But hey, still a good video.

[@OrdniformicRhetoric]

The link isn't in the description, but he puts it on screen. It is: databookuw.com/databook.pdf At the time of my writing of this comment the link is working

[@marc-andredesrosiers523]

I think it would be pertinent to connect this work to Judea Pearl's work on Directed Acyclic Graphs. The intention of this work will often live at the intervention or counterfactual steps in th3 ladder of causality. It would be important to acknowledge it. If only from a legal perspective, where, in a suit, these matters are criticcal.

[@user-if1ly5sn5f]

7:22 i had a weird thought, what if we are the detectors and through our detected differences reality is within view? maybe thats just a thought in connection to the growth of information through each other but maybe this detector isnt just us but the other things around us too and they are sort of detecting us. Like a push pull thing with the differences of reality and we grow just as it grows in difference throught the connections. Maybe thats why evolution works the same as quantum mechanics just with these differences?

[@michaelbacqalen1109]

With chemistry, there are principles and rules but there are also a lot of grey zones, exceptions, irregularities and anomalies lying in chemistry that are ready to pounce at you

[@abdjahdoiahdoai]

would this cover some topics in geometric deep learning or Lie theory used in DL?

[@jayeifler8812]

As a game programming kid in the days of text adventures, I realized we were trying to simulate reality. I became worried with the burden of having to model physics when I didn't already know it. Like how to model light in a hallway? Of course that's been done over and over anymore.

Hey, great lecture. Just want to know if this is a good field to explore and do a research on this in my undergrad (final year), if anyone could guide me here..?
