Aleksey Vyazmikin:

I am struggling with catbust, I can not understand what metric is better to use to select a model from this list for classification?

For myself so far I see an interesting variant of the formula %Regular from all*%Of target 1, but I do not see something similar there.

Accuracy

 
Maxim Dmitrievsky:

Accuracy

This does not work if the number of ones and zeros is unequal, as I have for example....

BalancedAccuracy

 
Maxim Dmitrievsky:

I don't know how... somehow :) well, there are criteria for selecting models - at least this minimum, MSUA, again, I recommend to read

I.e. in your language - choose the best one among a lot of indicators... already something :)

I haven't got to MSUA yet, I'm reading a lot, but I'm still in the thick of mathematics again

about the indicators - that's a great idea! but you have to look at it from another angle... I need to visualize your examples, or rather visualize the learning process

 
Maxim Dmitrievsky:

BalancedAccuracy

I don't quite understand what are the settings there, what are the coefficients, how do I apply them correctly?

Roffild did it here, I think... he visualized forest as an indicator

I dunno, I did not use )) maybe something simpler? AdaBoost or LightGBM... They're all the same thing, in essence. As for boosting, so is boosting

 
Maxim Dmitrievsky:

I don't know, I haven't used it)) maybe something simpler? AdaBoost or LightGBM... It's all the same thing, basically.

As far as I know, they can't be run from the command line, you need python or R, which is difficult for me... And we're talking about metrics, I thought it's a standard thing and doesn't depend on model creation package...

well the metric number of correctly guessed zeros divided by the total number of zeros. the same for units, then the total multiplied by 0.5

weighted metric it turns out

 
Maxim Dmitrievsky:

well, the metric is the number of correctly guessed zeros divided by the total number of zeros. the same for units multiplied by 0.5

the weighted metric comes out.

And the coefficient for shifting the weights? As in, if the most important 1, their weight is greater, or what?
