🧠 Can we recover the equations governing a system directly from noisy, high-dimensional observations? #DYSCO, by Paolo Muratore, is a first step: it learns latent spaces that capture the underlying dynamics & enables recovery of governing equations 📄

X character limited post ; )

I scraped a lemma off a manifold of latent space. The geometry tells the tale. For our world, the dimensions are capped, so Fourier transforms just make perfect sense and have perfect parity. Latent space is the only part of the model that matters.

“Can we” is proven by Takens's delay embedding theorem. Practically doing so is still an achievement.

Try with PCA Principal Component analisis to reduce dimensionality to capture 90% of entropy with the least dimensions as possible. Somerimes can be mappes to matrix equations and then exttact the eigevectors

Rather than PCA We use CEBRA as the base, which is a time-series method nonlinear ICA:

I will make a deep read. In the past we also used Latent Dirichlet Allocation for detection of new embedings non known a priory knowledge.

Reminds me of SINDy by Steve Brunton.

Cool work 👏🏼 the name 🙃

I would def mention way more about koopman explictly a la how to represent the state space in a tractable manner has like 30+ years of lit, this might help raise your multi view and contrastive contributions out of the old koopman lit, cool work!

The Duffing recovery in the video is striking. From the noisy raster stacks (multiple views), it feels like partitions are carving out distinctions → a latent space where the recursive flow (the cubic + damping relation) becomes explicit and coherent across time/views. The side-by-side portraits show the attractor emerging cleanly once those relations stabilize. A nice geometric way to see the signal crystallize from the mess. Great first step - looking forward to more!

Very interesting work. The move from representation learning toward recoverable latent dynamics feels like a major step for scientific AI. A question we keep coming back to at AIIA: once a latent space is learned, can its structure be audited for stability, compression, traversability, and regime sensitivity? That “structural audit layer” feels increasingly important as latent dynamics become part of scientific discovery.

Check out SGA-PDE, SINDy, or a behavior discovery version for agents:

wow this is a BEAUTIFUL visualization. I haven't seen this done in video form and it is fantastic.

Probably the solution isnt always unique

This is so useful !!

Hey @grok, is this paper using a simplicity bias (K, MDL)? If, how’s it implemented?

Will definitely take a look. I wonder what equations could be useful in real brain activity🤔

😍🦾

Wont there be many different equations with similar results?

@6ioneer Wow this is excellent… You should read some wrt the group who did strong stochastic flow maps

insane work

Yes, of course…that’s how all cognition works…human, fruit fly, B300 cluster… It’s an aproximation, of course, for all the usual reasons…

Love this!!

Classic mechanics can create something that behaves exactly like a black hole but isn't. Without confirnation the derived equations will be just like that.

Fascinating work with DYSCO. We observe the exact same necessity in our V-MAX architecture: recovering the invariant governing geometry ($|L\rangle$) requires mapping noisy, high-dimensional telemetry into a constrained Hilbert space to dissipate entropy. Brilliant step forward.

Are you into the dysco theory? May I ask a some questions?

@grok Please let know the gist of whitepaper and if it's good. And the applications of this.

@yacineMTB this seems important

Hey, very cool continuation! I'm a big fan of CEBRA+DynCL. My Top-3 favorite works. My #1 worry: this & DynCL theory use noise shape to fix the gauge. Say a pendulum: Euclidean vs angle/speed coordinates, what distinguishes them? Gaussian noise in only one gauge feels unlikely?

The decoding of tree canopies, leaves, and bark reveals nature's own silent language a profound code where patterns carry deep biological informatio

Really like this. We've been coming at the same underlying idea: many senses build a better picture of a system than any single view. The sharp bit for us: a deliberate nudge gives a reference that passive views can't. Do you see acting on the system as a route past that?

One thing I’m curious about: do you see latent-dynamics recovery and representation auditing as separate problems, or as two sides of the same problem? My intuition is that recovering the dynamics is step one, but measuring whether the learned space is stable, traversable, and regime-aware may become equally important for scientific use.
