Oh. Right. I didn't think about that interpretation .. Sorry if it seemed that way, I was just joking about the 80-20 rule in general, not about you.

Still interested to learn what triggered you :)

80% of the authors think they belong to the 20% ;)

(I do wonder what triggered your post..)

Yes! No overreview or openleaf yet, though...

Any idea why this effect happens? πŸ€”

How high-res can you go? And where can I order framed versions for in my office? πŸ˜€

(Or should I keep it intentionally pixelated by NN-upsampling to my desired dpi πŸ€”)

Haha, might be good to brush up on it, as multiple of the "Nullius" podcast episodes are things he wrote about πŸ™‚.

I do wonder why you think it's overly simplistic, but then I first will need to hear the podcast πŸ™‚. Because I tend to agree with Strevens, but looking forward to being proven wrong πŸ™‚

Strevens: Knowledge Machine

In "The Knowledge Machine", Strevens argues that there are no bad incentives in science, as long as empirical results come out πŸ™‚.
(Excluding fraud..)

But I should first listen to this episode, before I speak my mind πŸ˜‚. Nice topic πŸ™‚

Bibliography cleanup is known to be harder than AGI. Same with successfully connecting a laptop with a projector. It's what we humans will be doing long after the robot takeover. πŸ˜‡

I also like them. I think because they are tickling my brain to see meaning (where there's none)

Sometimes reminiscent of reviewing for cvpr πŸ˜‰

Strevens: Knowledge Machine

I found The Knowledge Machine a solid read on what science is:

Sorry for the unclarity πŸ˜…. I was wondering if a textbook is a "review" (it has limited novelty, I hope πŸ˜…). And, as such, if it's allowed on arXiv πŸ€”

I think I have seen them on arXiv in the past..

What about textbooks? πŸ€”

Well. At least they validate that deep learning methods might suffer from overfitting πŸ˜…

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

Looks great!! Wonderful work. Is this tied to a research field? Or can it be used generally? πŸ€”

But more on topic: our university uses Microsoft everywhere. To change that would require a fight. One that I am not sure if I want to take upon me.. πŸ˜…

Haha, well, I was also thinking about CoordConv, the paper that added position info to convnets :)

(Which, interestingly, seems to go against that finding that convnets can already encode absolute position πŸ€”)

I've been also thinking about position embeddings :). I might investigate with a MSc student, although that is still a while before they start.. πŸ˜…

Ahaa! "negative impact" is a continuous term, not discrete.

Now I understand why they were even threatening to desk reject one of my papers that was already desk rejected ;)

(We didn't make it in time so it was already out..)

Oh, i found the "urgent! Risk of desk reject when co-author reviews not done" quite exciting ;)

Interesting! Even in a time where the last bastion of "knowledge based visual feature engineering" (ie: geometry) is replaced by learning (eg: VGGT) ?

Does it have to be 3 years? πŸ€”

For a failure, I can recommend my own TPAMI 2010 paper on "visual word ambiguity", exemplified by:
- not end-to-end (feature engineering)
- grayscale only
- convexity assumption
- small datasets
- ... (?)

I misread it as "chess cake" πŸ˜‚.

Or should it be "check, cake"? (With the bishop πŸ™‚).

You taught the 17y old to play well, nice position πŸ™‚.
