"The simplest way to perform the copying task perfectly would be to duplicate the signal."
Whisper Note
Duplicating the signal defeats the whole purpose, obviously.

"An energy function is a macroscopic measure of a network's activation state."
Whisper Note
Wait, so lower energy means better? That's like the opposite of what I'd expect from "energy".

"The simplest way to perform the copying task perfectly would be to duplicate the signal."
Whisper Note
If it's just copying, why not use a tape recorder?

"An energy function is a macroscopic measure of a network's activation state."
Whisper Note
So it's basically using physics jargon to describe how the network settles into a stable state. Cool.

"Diffusion models are inspired by non-equilibrium thermodynamics."
Whisper Note
But how is that different from just adding noise, though?

"Graph neural networks (GNNs) are artificial neural networks designed for tasks whose inputs are graphs."
Whisper Note
I've seen these used in drug discovery, pretty cool stuff actually.

"Diffusion models are inspired by non-equilibrium thermodynamics."
Whisper Note
Makes sense why my physics background finally pays off.

"Diffusion models are inspired by non-equilibrium thermodynamics."
Whisper Note
So basically they're just fancy thermodynamics, huh.

"autoregressive (AR) model is a modelled representation of a type of random process"
Whisper Note
I used to think AR meant something from my car stereo. Learn something new every day.

"autoregressive (AR) model is a modelled representation of a type of random process"
Whisper Note
So basically it's just saying history repeats itself, but with math.

Original Highlight Excerpt
"models the log-odds of an event as a linear combination of one or more independent variables"
Whisper Note
so it's basically a linear model but for probabilities, neat.

"optimal lower bound $\frac{\lambda_n}{\lambda_m}\geq(\frac{n}{m})^2$ of vibrating string"
Whisper Note
Huang's method again—that trick with zeros of eigenfunctions is really neat.

Original Highlight Excerpt
"optimal lower bound $\frac{\lambda_n}{\lambda_m}\geq(\frac{n}{m})^2$ of vibrating string"
Whisper Note
I've seen this ratio before for constant density, but concave makes it way more interesting.

Original Highlight Excerpt
"optimal lower bound $\frac{\lambda_n}{\lambda_m}\geq(\frac{n}{m})^2$ of vibrating string"
Whisper Note
So the bound is optimal only when the density is concave—that's a pretty strong condition.

"It can be interpreted as compressing the message, or reducing its dimensionality."
Whisper Note
But doesn't reducing dimensions always lose some info? I'm skeptical.

"Zero-shot learning (ZSL) is a problem setup in machine learning where, at test time, a learner observes samples from classes which were not observed during training"
Whisper Note
We used this for rare animal species, it actually works better than I thought.

"Geometric transformations alter the spatial properties of images to simulate different perspectives"
Whisper Note
Makes sense, but doesn't this just mean rotating and flipping pictures?

Original Highlight Excerpt
"emergence occurs when a complex entity has properties or behaviors that its components do not have on their own"
Whisper Note
I've seen this in traffic jams—cars together create chaos no single driver does.

"emergence occurs when a complex entity has properties or behaviors that its components do not have on their own"
Whisper Note
Sounds nice but isn't it just a fancy way to say the whole is greater than its parts?

Original Highlight Excerpt
"Indoor localization services are a crucial aspect for the realization of smart cyber-physical systems within cities of the future."
Whisper Note
This is the key reason why smart cities won't work without solving indoor positioning first.
