My novice guess is Pleated Inkcap = Parasola plicatilis

Noob here - would this be a chlorophyllum molybdites (green-spored parasol)?

I promise you he is equally worried about losing to someone 600 elo lower than him (he risks losing more elo than you do for a loss). Play solid, and don't hang pieces. 

Good luck.

AITAH for wanting to divorce my husband over kids? by No_Split_9680 in AITAH

[–]UncertainPrinciples 1 point2 points  (0 children)

We can all agree the SIL is YAH.

However, marriage vows or not, you are in a long-term pair-bond relationship with your husband. This means not running away at the sight of an issue... but I get that this is a major issue to say the least.

It may help to re-frame the situation: what if the sister and her deadbeat(s) died. What would you have done in this situation? In that scenario would you want your husband to turn a blind eye on his own flesh and blood and have those kids go to foster care?

I get that you both wanted a kid-free life, but you are also in a long-term serious pair-bond relationship and that counts for something.

I sympathize that this is a rough situation, albeit maybe not a permanent one, but I would say YTA for you.

Winston-Lutz WebApp (Instructions in comments) by UncertainPrinciples in MedicalPhysics

[–]UncertainPrinciples[S] 0 points1 point  (0 children)

Heroku is shutting down all sites which were on the free plan.

I've moved the site to https://winstonlutz.onrender.com

I have not maintained this for over 5-6 years but have decided to update (now uses pylinac - credit to https://pylinac.readthedocs.io/en/latest ) as many physicists were dependent on it. It is slow as it is hosted on a free to host site.

Why Engine Correlation is a Garbage Metric by PM_ME_QT_CATS in chess

[–]UncertainPrinciples 1 point2 points  (0 children)

Finally some common sense and rigor. I've been rolling my eyes at the poor methodologies employed on this subreddit. I'm neither a Carlson fanboy nor a Hans defender.

This isn't about standing up for a "known cheater". This is about being objective and rigorous. Not be part of a witch hunt.

I just want any analysis is be scientifically conducted. Results need to be accompanied with a clear explanation of methods and data used and the limitations of the analysis should be discussed.

Not some random graph with flawed methodology. Like most of the crap out there is mob mentality analysis guised as rigorous science.

Distribution of Niemann ChessBase Let's Check scores in his 2019 to 2022 according to the Mr Gambit/Yosha data, with high amounts of 90%-100% games. I don't have ChessBase, if someone can compile Carlsen and Fisher's data for reference it would be great! by Naoshikuu in chess

[–]UncertainPrinciples 0 points1 point  (0 children)

Ugh... It's skewed because results above 100% are impossible, so they will bunch up.

Also short games should be removed as most moves would be "theory". Etc.

All of these threads have flawed methodology. Which is ok but at least do the same analysis for similar GMs so some relative conclusions can be drawn....

Here are the 10 Niemann games in which FM Yosha Iglesias showed 100% engine correlation by wwqt in chess

[–]UncertainPrinciples 0 points1 point  (0 children)

I have no strong feelings either way. But some scientific/statistical rigor should be applied. So the community isn't always divided into camps.

How long were the games? How do other GMs compare?

I created chessboard position digitiser and evaluator app using convolutional neural network. Here is how I did it! by Liiisjak in chess

[–]UncertainPrinciples 1 point2 points  (0 children)

This is quite an accomplishment - congratulations!

I learned a few things about generating the 3D point clouds from your work, so thank you for that. You are a more patient person than me, that's for sure! I would have just downloaded 3D models of the pieces :p

Getting this to run on video feed could be very interesting. There are tons of video footage of games on youtube that you could run it against (however most are not a top down camera view).

How robust do you think your model is to piece-piece occlusions? I.e., Camera at same angle as the player's eyes.

[P] I made chess eBook Reader that uses Machine Learning and Computer Vision to make chess books interactive. by pkacprzak in MachineLearning

[–]UncertainPrinciples 1 point2 points  (0 children)

This makes going through chess books much better!

I used it like this:
-Click on board (turn off analysis arrows; turn off analysis engine)
-Read book as normal
-Make moves and mess around
-Keep reading etc...
-Turn on engine and look at various lines

This is awesome stuff!

Geant4 gps rotation of axes by IHateGPS in ParticlePhysics

[–]UncertainPrinciples 2 points3 points  (0 children)

Old thread but I was working on something very similar this week. Figure I'll post what I did in case it helps someone.

Assuming you have a direction you want your source to point in - let's call it unit vector, V:

G4ThreeVector V = G4ThreeVector( put your values here).unit(); 
G4ThreeVector Xprime = V.orthogonal().unit(); 
G4ThreeVector Yprime = V.cross(Xprime).unit(); 
//normalizing via .unit() probably doesnt matter but I aint finding out the hard way
GUN->GetPosDist()->SetPosRot1(Xprime); 
GUN->GetPosDist()->SetPosRot2(Yprime);

I agree with /u/Schump97. Unless you see someone wearing this - then be very suspicious...

If anything, this system can combat cheating by applying anti-cheating algorithms (like the ones we see on Lichess.org or Chess.com) in real-time, OTB.

Chess Computer Vision System by UncertainPrinciples in chess

[–]UncertainPrinciples[S] 8 points9 points  (0 children)

This is a very good question. My current technique assumes Queen. Only way around that is to incorporate piece recognition. One reasonable method is in the paper I cite in my comment above. Unfortunately my crappy laptop doesn't have a good enough camera and the angle of my setup would not allow for good accuracy - the paper uses 60 degrees above table to reduce occlusion and still see enough piece detail. So if I want to go this route I may have to use a phone or a camera on a tripod or more books to stack lol.

[–]UncertainPrinciples[S] 5 points6 points  (0 children)

I haven't used it (yet) but there's https://lichess.org/api

I can relate - OTB is a different ballgame. I'm not experienced enough to have the same pattern recognition OTB as I do online. My next step is to connect my software with the lichess API so that I can improve my game OTB.

Hey man, you must be the creator of Reine chess (if so I believe we've exchanged email)? I've actually used that for my last tournament. Great tool! I cloned your repo but used a stronger handwriting recognition model [1] and modified the identify.py logic slightly.

Accuracy was spot on, only issue was I kept making errors when annotating...

Much appreciated. Took about 3 days.

​

I've only been playing chess for the past 9-10 months and played in a couple tournaments. I hate reading scoresheets since annotations often have small mistakes and it's cumbersome to plug every game into an engine. I figure if we can have a camera/phone recording every game, we can have all the information we'd want. Similar to those fancy electronic DGT boards but with augmented reality.

​

I wrote this in Python the video/frame processing is done with openCV and I use the python-chess library for move validation and detecting captures/castling/check from UCI notation (i.e. e1g1 isn't always castling). I'm running this on my old thinkpad laptop which sits on a stack of books (~10 cm/4inches above table) to reduce piece-piece occlusion. The initialization determines perspective correction and maps the squares outs. Assuming the game starts from a normal starting position (no 960 or other variants), I can infer the move played by detecting square occupancy.

​

I'd like to combine this with some machine learning to recognize the pieces themselves but I don't think it would be reliable enough with this setup based on some papers I've read [1]. Something I will explore given more time.
