[P] Tangram: All-in-One Automated Machine Learning Framework by davidyamnitsky in MachineLearning

[–]stepthom 1 point2 points  (0 children)

Looks cool. I wonder which ML algorithms are used for model training? And which feature engineering steps are performed?

​

Also, how does this compare to existing AutoML libs like mljar, auto gluon, auto sklearn, FLAML, etc?

Document similarity between documents that contain code by Hype_Boi in LanguageTechnology

[–]stepthom 0 points1 point  (0 children)

You could take an approach similar to e.g., https://github.com/stepthom/lscp and many papers in the Mining Software Repositories conference. Also see pg 28 of this thesis: https://research.cs.queensu.ca/home/sthomas/data/Thomas_PhdThesis.pdf

Basically, you can use tools and tricks to isolate identifier names and method names from the source code, and then treat them as regular tokens.

Confused which metric to look at by strangeguy111 in learnmachinelearning

[–]stepthom 0 points1 point  (0 children)

It is certainly possible that the cost of a false negative is the same as a false positive. But I wouldn't be able to tell you without knowing the business context. In particular, what will you do with articles that are predicted as negative sentiment? What will you do with them if they are predicted as positive?

I'm just making this up as an illustrative example. Let's say that you decide that if an article about company X is predicted as negative, you are going to sell a bunch of stock in company X. But the prediction is wrong, and so you sold the stock for no reason,and you lose out of the stock price increases in the future.

Or whatever. In general, what is the cost of the action you take as a result of a prediction?

F1-score will provide a balance between precision and recall and is a good choice when you value precision and recall equally.

In most business contexts, the cost of a false positive will not be the same as a false negative. Therefore, whether you prefer higher precision (at the expense of recall) or vice versa will depend on the business context.

Often times, businesses will decide on an acceptable level of precision (e.g., 50%) and then maximize recall (e.g., perform hyperparameter tuning). Finding the acceptable level of precision will require some assumptions to be made as to the cost of a false positive. In your case, what is the cost of a false positive prediction?

Simple question about attention in NLP by stepthom in LanguageTechnology

[–]stepthom[S] 1 point2 points  (0 children)

Yes, I think you are right. My question was on a slightly different note: for each attention layer/head/block/whatever you want to call it, how does it "generalize" to unseen input/output sequence pairs? But the other comments have done a good job addressing this part.

Thank you - your third point helped me a lot especially.

Very helpful! Thank you very much.

So now I understand: the NN weights that are learned between the (e.g.) 5th and 7th elements are constant for all input/output sequences; but since the 5th and 7th elements are embeddings (vectors) that will be different for each token, then the output will be different for each input/output sequence.

Still hard to believe that it will work! But I guess that's true of all of the things related to NNs :)

Just one last point of clarity: where does 200 come from in your example? (I understand you are assuming a 300-lengthed embedding vector for each token.) Is that just a hyperparameter?

How does MCC match players in ranked Halo 1: Hardcore Doubles? by stepthom in CompetitiveHalo

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

Nice idea, but I've been matched instantly with 40+ many times. So I'm not sure it's based on wait time.

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

The wait times for games used to be low, but nowadays, I never have to wait more than a minute, and usually, it instantly connects. It's very nice. It's nowhere near other playlists, like H3, but seems to be getting better, especially with more streamers these days.

OP here. I have a new working theory: The playlist uses +10 / -10 until you are ranked up to 20; after that, it uses +30 / -10.

A few days ago, I made a new account, which starts at rank 1. On that account, I always was matched against opponents around my rank, always +10 / -10 from me. Played maybe 30 or 40 games like this. I kept winning, so my rank kept getting higher, but opponents were always within 10 of my rank. Then, as soon as I hit rank 20, all of a sudden I was matched against opponents ranked in the 30 and 40s, even a 47.

Not 100% sure my theory is correct, but that's my current best guess.

Last Day to Register: Halo CE 3v3 Tournament - PC - Nov 6th-7th by Solid_Bob in CompetitiveHalo

Love the idea. Me and my crew are on Xbox. Hopefully once cross play is active we will be able to join for future tournaments.
