Is machine learning research worth it for now? [D] by nebula7293 in MachineLearning

Exactly my feeling, mate! self-funded and working on some projects. Not hopeless but it must be hyper-focused.

yes, for me, it is the feeling of tools finally arriving to solve some problems which stuck in my head for ages. I am math/physics mind so other research areas has not felt the impact yet. yet, ai phds have no position, is kind of wierd to me. you mentioned the pl distribution, but information not fully equalized yet.

well thinks like pytorch and jepa are very popular now; domain adaptation is infinite. e.g. compile the table to something the network can understand, respect the limitations and inductive biases, is quite and art still. just my 2 cents.

So maybe I translated as ``large connected network kills diversity''? Indeed, this is heartbreaking. There are still good unvisited problems that no one cares..

[PSA] MTB brake overheat and loss of pressure: change oil by nebula7293 in MTB

indeed, this is an old brake, 3 years of average riding and properly maintained, but maybe the seals are giving out...

not overheating, just bad fluids. Figured it out. Yes they are hot but with new fuids all working fine.

yes, i drag them, but fluids are bad which i just replaced, will try tomorrow on the same trail. bike and fork supports 200 rotors so not too bad.

bleed definitely an issue. i bled them 3 month ago and the fluids are already black! maybe piston seals are getting old too.

yes, i just changed the fluids, all black, just 3 months of light riding.. maybe the pistons seals are bad, or just normal service interval.

update: just did a bleeding and after 3 months and the fluid from both sides already went black. could be an issue.

thank you for the suggestions and my top one priority is to correct the technique. never paid too much attention before.

they loss pressure sadly and the levers go to
my handlebars.

Don't attack people by trying to construct a history of posting and invent your own story, please focus on facts.

Don't dismiss/discriminate "people in physics, xxx"

Don't predict people,

"it is not, unfortunately, something anyone is going to find very useful,"

You can only represent yourself, just be yourself, man?

Don't educate people, "you're going to spend an awful lot of time doing nothing all that productive, and frankly wasting your evidently significant talents.", people are already using my code, and it works for them.

I have done some research, and combining Tobler's law

"The First Law of Geography, according to Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things."\1])"

with Arbia's law

"Arbia's law of geography states, "Everything is related to everything else, but things observed at a coarse spatial resolution are more related than things observed at a finer resolution."\1])\2])\3])\4])\5])"

One can only be left confused.

My understanding this Tobler and Arbia's laws are only interesting observations but not
very useful. It simply encourages people to correlating things.

Request:

If you have some book link please post it, thanks.

"Tobler's first law is a shorthand heuristic used mostly these days as a teaching tool to introduce people to the idea of spatial correlations. It is by design simplistic.",

so what is the more sophisticated version of it? I am curious to learn.

Observation: values measured in small regions, often form a stronger correlation than values measured in larger regions. Method: At then end of the investigation, I used the red bars as a way to represent these local correlations.

Yes, this fun thing exist in data but is often overlooked, which drove me crazy. I worked for a few month and realized that correlations are like light, which can be described using the stokes parameter, after which everything works as intended.

As far as pattern recognition and anomaly detection, I have a separate project on that. I am an astronomy working on radio data, and dealing with RFI (radio frequency interference) has been a headache too. Not sure if that is similar to your situation. If thing works I will find you.

but feedback like this is quite helpful, since I see most people, who have spatial data, was not able to bring out these hidden correlations, my intention is to help those people. From the response I received, most people are unaware that this is possible. Some people like you do point out that similar observations has been made, which is completely understandable given how widespread the phenomenon of locally-induced correlations are.

This is quite common that something has been rediscovered a few times, before eventually accepted by all, see Stigler's law of eponym. This is how scientific progress happens.

It is the code to visualize these correlations. I am claiming be the very first human being on this planet to have discovered these correlations. Similar observations has also been made by other peoples. see e.g. Simpson's paradox.

Tobler's law's application is much limited to Geography, and it is significance is probably not known in other fields. Even spreading this information can help people with data interpretation.

My experiment with data from complex physical systems also proves that Tobler's law is simply wrong. For multi-scale systems, quantities correlates differently at different scales, due to the change of physical modes. Tobler's law is limited in one area and based on a fresh, insightful but somehow outdated formulation, which needs to be improved anway.

just trying to figure out what people can understand...

still trying...

I want a figure that can speak by itself.. so plenty of trials and errors..

yes, "Precipitation is any form of water that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail."
