andersourceon Fifteen Years

This is a reference to the "wanna feel old?"-style comics, another recurring xkcd theme, for example [0], [1]. But yes, feeling old sucks.

andersourceon Nobody has a personality anymore: we are products with labels

Is there a diagnosis for the tendency to collect diagnostic labels and use them to absolve oneself of responsibility?

On further thought, not sure if this would solve the problem or exacerbate it...

andersourceon Sequence and first differences together list all positive numbers exactly once

Ah :)

From my (limited) experience the OEIS titles lean strongly to the descriptive side too. But maybe also to avoid ambiguity regarding to which one is it from his sequences?

andersourceon Sequence and first differences together list all positive numbers exactly once

Hofstadter introduces several sequences in GEB, [0] may be an interesting submission on its own but I was especially captivated by this self-referencing one. Plus a title including both Hofstadter's sequence and a description is too long for HN and I preferred the descriptive one

andersourceon Adventures in Imbalanced Learning and Class Weight

Really neat visualization! And thanks for the tip on MCC.

Out of curiosity I plugged it to the same visualization (performance vs. class weight when optimized with BCE) and it behaves similar to F1, i.e. best without weighting.

andersourceon Adventures in Imbalanced Learning and Class Weight

Yeah it gets tricky. I think eventually it has to be about tradeoffs - no ML system can be 100% correct. I do think there's a "right" decision (up to a point) in the context of the product or business.

andersourceon The FFT Strikes Back: An Efficient Alternative to Self-Attention

A fully connected layer has different weights for each feature (or position in input in your formulation). So the word "hello" would be treated completely differently if it were to appear in position 15 vs. 16, for example.

Attention, by contrast, would treat those two occurrences similarly, with the only difference depending on positional encoding - so you can learn generalized patterns more easily.

andersourceon The unbearable slowness of being: Why do we live at 10 bits/s?

If the questions were pre-determined, which they're usually not. Reminds me of Huffman coding and the reason that compression challenges measure submissions looking at artifacts required to run them in addition to compressed size. I tend to agree with OP that this doesn't pass the smell test

Thanks!

andersourceon Ask HN: What are you working on (August 2024)?

Preparing my PyCon IL workshop, a competitive platform where you write code to solve simple games (think snake, pong etc.). Here are some screenshots: https://imgur.com/a/VDKfmjO

After it's done I hope to add a demo to my blog.

Cheers for all the interesting work going on here!

andersourceon What kind of bug would make machine learning suddenly 40% worse at NetHack?

I can imagine it's a bit like if gravity suddenly changed to 0.9g. Everything(?) is easier but a lot of people would probably stumble around a bit before muscle memory, coordination etc. get used to the change.

andersourceon People can read their manager's mind (2015)

I was pretty much like this for a long time, 1 / 10 would not recommend. For me the change was gradual but basically it was a couple of realizations revolving around separating my identity from my career and finding personal stuff I'd rather pour my emotional energy into, instead of pouring it to fight my employer to do things I thought they should be wanting me to do.

andersourceon Ask HN: How to do that you need to do but not motivated at all?

I'd echo other comments suggesting examining closely what you really need to do (e.g. "how to be productive" is a very loaded question for me, modern society tends to way overemphasize the importance of "being productive" to the detriment of many.)

If you really are struggling doing things you absolutely have to do, my suggestion is using an exhaustive TODO list where each action item takes ~10 minutes, that can get you rolling relatively fast. Happened to write about it recently here[0] as I was experiencing something similar.
