原文高亮摘录
The simplest way to perform the copying task perfectly would be to duplicate the signal.
Whisper 随想笔记
Duplicating the signal defeats the whole purpose, obviously.

原文高亮摘录
An energy function is a macroscopic measure of a network's activation state.
Whisper 随想笔记
Wait, so lower energy means better? That's like the opposite of what I'd expect from "energy".

Whisper 随想笔记
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 随想笔记
So it's basically using physics jargon to describe how the network settles into a stable state. Cool.

原文高亮摘录
Diffusion models are inspired by non-equilibrium thermodynamics.
Whisper 随想笔记
But how is that different from just adding noise, though?

原文高亮摘录
Graph neural networks (GNNs) are artificial neural networks designed for tasks whose inputs are graphs.
Whisper 随想笔记
I've seen these used in drug discovery, pretty cool stuff actually.

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

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

原文高亮摘录
autoregressive (AR) model is a modelled representation of a type of random process
Whisper 随想笔记
I used to think AR meant something from my car stereo. Learn something new every day.

Whisper 随想笔记
So basically it's just saying history repeats itself, but with math.

原文高亮摘录
models the log-odds of an event as a linear combination of one or more independent variables
Whisper 随想笔记
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 随想笔记
Huang's method again—that trick with zeros of eigenfunctions is really neat.

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

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

原文高亮摘录
It can be interpreted as compressing the message, or reducing its dimensionality.
Whisper 随想笔记
But doesn't reducing dimensions always lose some info? I'm skeptical.

原文高亮摘录
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 随想笔记
We used this for rare animal species, it actually works better than I thought.

原文高亮摘录
Geometric transformations alter the spatial properties of images to simulate different perspectives
Whisper 随想笔记
Makes sense, but doesn't this just mean rotating and flipping pictures?

原文高亮摘录
emergence occurs when a complex entity has properties or behaviors that its components do not have on their own
Whisper 随想笔记
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 随想笔记
Sounds nice but isn't it just a fancy way to say the whole is greater than its parts?

原文高亮摘录
Indoor localization services are a crucial aspect for the realization of smart cyber-physical systems within cities of the future.
Whisper 随想笔记
This is the key reason why smart cities won't work without solving indoor positioning first.
