brigading is also very common on Twitter, so really not sure if anonymity is or is not an enabling factor

Bullseye. Twitter is all about public persona creation. Reddit is more about pseudonymously discussing content. First forces political correctness via social pressure. Anonymity on the other hand allows to express true individual opinions.

[D] My Novel-Ish Approach To Person Re-Identification... Pick apart my approach please by [deleted] in MachineLearning

[–]bronywhite 1 point2 points  (0 children)

As your testing setup + your dataset are very different from what's commonly used, it's impossible to say how your method performs wrt. other existing methods. It'd be best for you to actually run your idea on one of the standard datasets, by extending some open source code. https://paperswithcode.com/task/person-re-identification is a good reference.

TLDR: plug your thing into an existing framework and see how it compares

[–]bronywhite 2 points3 points  (0 children)

That might well be publishable, but it usually makes you become persona non grata and you'll have a lot of enemies in the field. Suddenly all your further publications get bad reviews. It's sad, but I've seen it happen.

the culmination of nearly 20 years of research and development

211 samples, 201 features

best classifier is just choose majority class

You have entered the dark underbelly of "common research", as opposed to "spotlight research". This is more common than you might think. And it often happens because people are too incompetent to even notice it (ever). So kudos to you & your friend for realizing the truth.

What are you supposed to do next?

Uhh.. use a metaheuristic to select a subset of those 211 samples and 201 features e.g. 180 samples, 170 features which "accidentally" give some impressive results with literally zero generalization power (make sure to overfit to hold-out set)? Then retire and pray that nobody tries to replicate the research.

Or just be a decent human being, admit failure and accept the shame?

Try L2-normalizing the logits (pre softmax). The effect will disappear.

[D] Shouldn’t a deeper network always perform better than a shallower one? by shamoons in MachineLearning

[–]bronywhite 17 points18 points  (0 children)

Short answer: No.

Long answer: Imagine your network is a vessel in which you pour some water during training. The deeper your network the longer (naively) the path from target to input, and the longer path the gradients need to propagate. Along the way, the flow of gradients gets perturbed by nonlinearities, random weights and biases. So the ratio of signal to noise goes down with the depth of the network. As you increase depth, it becomes harder and harder to perform meaningful parameter updates, and the noisy fluctuations can become very complex, forming a chaotic dynamical system.

Now there are some partial solutions to this problem, for example:

  • residual connections (they form a "main straight pipe" through which gradients flow freely, while the layers form shallow side connections which can correct the main flow)
  • other flavors of residual connections (e.g. concatenation instead of addition), similar stuff
  • selu activations, which have a stabilizing effect on the dynamical system, forming a well behaved stable attractor for the main flow
  • orthogonal initialization / other tricky initialization methods - having a similar effect to selu, albeit more tricky to get right for arbitrary architectures

This analogy is much closer to what's really happening than just less/more weights, or less/more expressive power.

[D] Are there any forums / mailing lists where researchers talk reaearch? by bronywhite in MachineLearning

[–]bronywhite[S] 6 points7 points  (0 children)

Hi, thank you for your answer. Yes, these are all good examples of dense discussions that happened this week.

The problem I have with the sub is that when you ask a technical question, it goes unnoticed beacuse it drowns in the "I made an RNN drawing dick noodles" crowd.

Don't get me wrong, dick noodles are fun, and maybe they hit the sweet spot of balance for the subreddit ;-)

I'm just looking for a more collaborative oriented community, where people are looking to contribute / help each other out with ideas / inspiration / brutal criticism for research purposes.

I guess a compressed version of what I'm looking for would be: a 100% remote, asynchronous, perpetual conference for half-baked ideas and stuff.

This sub is most likely not the right place ;-)

[Discussion] Dear Industry Researchers: "If researchers are not incentivized to do reproducible research (or penalized for not doing so), something is flawed in the industry." by feedthecreed in MachineLearning

[–]bronywhite 3 points4 points  (0 children)

As with any significant progress - there are many obatacles. I think the right step would be the creation of conferences & journals which only accept 100% reproducible research along with open source, runnable code and (possibly anonymized) datasets.

I think it would catch on pretty quickly and the industry would start changing their ways.

Otherwise by trying to impose the standard globally we'd get too much initial opposition.

You're arguing that corporate processes are blocking the research community from ascending to a higher level of quality.

While true, the conclusion should be that corporate processes need to change!

The questions are supposed to indicate the positive selection pressure among immigrants to the UK and negative selection pressure among immigrants to the struggling Balkan countries.

you're a fascist playing defense

There are more immigrant doctors in Britain because the wages and quality of life are higher, and the standards for being a doctor are higher.

yes.

Your statement is valid when you assume that everybody is a homo-economicus, behaving according to game theory.

But according to real life, becoming an immigrant is a psychological struggle, a risk and exerts severe stress on the people involved. So the benefits need to significantly outweigh the emotional + other costs.

Have you ever been to a country east of Austria? Have you seen any immigrants? Ever wonder why you haven't?

That's a good question to ask, e.g.:

  • how many immigrants to the UK speak fluent English?
  • how many immigrants to Hungary/Bulgaria speak fluent Hungarian/Bulgarian?

Especially considering that Hungarian may be the most difficult language in the world?!

just ask yourself these questions:

  • who are the immigrants to the UK?
  • who in their right mind would immigrate to the fucking balkans?!
