"a comparison sort cannot perform better than O(n log n) on average"
Whisper Note
So that's why my custom sort is always slower than the built-in.

"the output of any sorting algorithm must satisfy two conditions"
Whisper Note
Even the definition sounds like a math test I'd fail.

"the output of any sorting algorithm must satisfy two conditions"
Whisper Note
Two conditions? I thought it was just 'small to big' and done.

"In a well-dimensioned hash table, the average time complexity for each lookup is independent of the number of elements stored"
Whisper Note
Average is the key word—worst case is still a nightmare though.

"The term machine learning was coined in 1959 by Arthur Samuel"
Whisper Note
Arthur Samuel coined the term way back in 1959, that's wild.

"Move semantics enable the transfer of resources and ownership between objects"
Whisper Note
This is exactly why modern C++ feels so much safer than the old pointer juggling days.

"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.

"Content-based filtering methods are based on a description of the item and a profile of the user's preferences"
Whisper Note
So basically it just matches what you liked before with similar stuff, right?

"A typical generative task is as follows. At each step, a datapoint is sampled from the dataset, and part of the data is removed, and the model must infer the removed part."
Whisper Note
That's how they train those language models? Seems almost too simple to work that well.

"The main difference between federated learning and distributed learning lies in the assumptions made on the properties of the local datasets"
Whisper Note
Huh, I always thought they were the same thing. This clears it up a bit.

"The key design element of GNNs is the use of pairwise message passing"
Whisper Note
So the whole GNN thing really just boils down to neighbors chatting with each other, huh?

"The main difference between federated learning and distributed learning lies in the assumptions made on the properties of the local datasets"
Whisper Note
So it's basically about who owns the data and how messy it is, got it.

"Graph neural networks (GNNs) are artificial neural networks designed for tasks whose inputs are graphs."
Whisper Note
So basically they made neural nets that can handle family trees and stuff?

"Aggregate functions compute a single result from a set of input values."
Whisper Note
So basically it's just like SUM or AVG but for any set of values, got it.

"A module is a file containing Python definitions and statements."
Whisper Note
I always wondered why __name__ showed up in scripts. Now it makes sense.

Original Highlight Excerpt
"A module is a file containing Python definitions and statements."
Whisper Note
So basically any .py file is a module? That's simpler than I thought.

"The autocorrelation function of an AR(p) process is a sum of decaying exponentials."
Whisper Note
So basically the memory fades out smoothly, like echoes getting quieter.

Original Highlight Excerpt
"A policy is a rule used by an agent to decide what actions to take."
Whisper Note
So basically it's just the brain of the agent, got it.

"Assignments do not copy data — they just bind names to objects."
Whisper Note
So that's why my list changes when I pass it to a function and modify it inside... makes sense now.

"Large language models are called autoregressive, but they are not a classical autoregressive model in this sense because they are not linear."
Whisper Note
Wait, I thought autoregressive just meant predicting the next word, why the linear caveat?
