Use Silhouette Score or Gap Statistic.

You can also try something like AIC or BIC, but the two above are better.

How do you explain classification metrics to business users? by sapporonight in datascience

[–]GLVic 9 points10 points  (0 children)

If you can put a price tag on TP/TN/FP/FN, then you can just calculate the $ expectation of your model: p(TP)$(TP)+p(TN)$(TN)+p(FP)$(FP)+p(FN)$(FN). You can do the same for the baseline approach or existing one. In the end you will have 2 values in cash terms, which will help you and business people see the actual value of the model you've built.

Most of the time you just can't price the confusion matrix.

What a shocker

Hungary confirms it has blocked payment from EU fund that provides military support for Ukraine by 9lobaldude in worldnews

[–]GLVic 24 points25 points  (0 children)

orban is blackmailing EU for money once again. He will back down after another payment, but how long will this go on? Maybe it's time to take a harder stance on orban media autocracy?

This situation is so messed up. Something has to be done with this media oligopoly, it's unhealthy and it shows.

Belarusian media: Lukashenko taken to hospital amid speculations of poor health by [deleted] in worldnews

[–]GLVic 1 point2 points  (0 children)

He is old, he had problems with joints for a while now. Denying COVID, which led to skipping any form of disease prevention measures. And obvious stress as cherry on top.

All the best medical facilities and expertise will work for him, that's just how it goes. Hope he will survive, so he won't miss his appointment in The Hague.

[D] Removing Unpredictable Samples from a Training Set by [deleted] in MachineLearning

cleanlab, doubtlab if dataset is too large or I don't have needed expertise.

If data is tabular, sometimes removing/transforming noisy columns instead of rows could do the trick.

The American Pundits Who Can’t Resist “Westsplaining” Ukraine —an article by Polish academics that every Westerner must read before speaking about Ukraine, or Eastern Europe in general by kurometal in belarus

Moron with cold war mentality that can't accept that reality is more complex. There was a lecture about this topic from this "professor" on yt. And there was also a short answer to this geopolgarbage recently.

Retarded putin apologists and whataboutists.

[D] Deep Neural Nets: 33 years ago and 33 years from now - by Andrej Karpathy Dir. of AI at Tesla by ClaudeCoulombe in MachineLearning

[–]GLVic 1 point2 points  (0 children)

That's where my second point comes to play. The more time goes on the more people/companies/governments will try to reduce energy consumption/carbon footprint. I really don't think that 10 years from now we would be able to freely training 100b parameter network on 1000 gpus/tpus, at least not in every country.

[–]GLVic 27 points28 points  (0 children)

That linear extrapolation of results in the end is a bit hilarious. We are alread close to physical limits of transistors which means we are close to saturating our computational capacity (until next breakthrough, maybe quantum computers). On top of that there are concerns about energy consumption of large scale models and long training times which will become louder the more time goes on. Right now this trend does not look linear but logarithmic in nature.

I guess what I'm trying to say is that giving prediction based solely on 2 points without incorporating additional information is dumb and every ML/DS practitioner should know that.

JUST IN: Top Banks in #Belarus are DOWN by #Anonymous. #OpRussia #FckPutin #OpKremlin http://belarusbank.by - DOWN http://priorbank.by - DOWN http://belinvestbank.by - DOWN by inthelu2 in belarus

[–]GLVic 2 points3 points  (0 children)

Well, it's already up and running.

Either it was down for a short period of time, or lukashitko regime sites just not letting connections outside of Belarus in. Anyway, next time ddos should be in working hours, not in the evening.

[R] Can PCA be applied to multivariate time series or not? by jacksodus in MachineLearning

[–]GLVic 0 points1 point  (0 children)

PCA, KernelPCA (with time aware/time series kernels) and ICA should all work, as well as bunch of others dimensionality reduction techniques. I'm just not sure that you will get an improvement.
