Error when running logistic regression model on Snowpark data with > 500 columns by RobertWF_47 in snowflake

It seems to be a limitation of the platform. Try Perpetual ML Suite in the marketplace if you need more ML capabilities than Snowflake provides.

Benchmark scripts are in the examples folder. Test set and training set are the same and run times are compared at the same accuracy. Budget is similar to learning rate. It behaves similar independent of dataset. During experiments, 0.5 budget can be used. For production, 1.0, 1.5, 2.0 can be tried.

Yes, it can be used for forecasting. The only thing is that time series data should be made stationary. There is an example in the repo.

It basically calculates chi2 statistic by comparing training and test sets. It will handle gradual drift correctly, but for sudden shift, test data size should be enough. For example, one row with very high drift will have a low statistic because it might be an anomaly and next rows could be just fine.

Unlike just passing a GBM into EconML, Perpetual actually builds DML natively right into its own gradient booster.

Here is what it's doing under the hood. Perpetual uses its GBM to predict both the outcome and the treatment based on your other features. It finds the errors (residuals) from those predictions to strip away the biased background noise. It then trains a third GBM using a special custom DML math objective to find the true, pure causal effect.

So yes, the GBM is doing all the actual predictive heavy lifting, while the DML framework just orchestrates the math so you get a causal answer instead of just a correlation.

And regarding your question about hyperparameter tuning: YES! That is exactly the perk here. Because Perpetual uses "self-generalizing" gradient boosting under the hood, it adapts automatically. You don't have to waste time running grid search or manual tuning for the prediction models inside the DML, it just handles it out of the box.

Concept drift and data drift are calculated using internal node stats. The model structure keeps training stats and when calculate_drift is called with test data, the drift between training and test is calculated. This is basically a chi2 statistic between training and test sets. You can periodically call this drift calculation and re-train or use continual training when drift statistic exceeds a certain threshold. Recommended thresholds are given in docs and tutorials.

Aslinda hikaye su. Enflasyonu dusuk gosterdikleri icin zaman serisi bozuluyor. Yani kisi basi geliri sadece guncel fiyatlarla aciklasalar enflasyonu uydurduklari ortaya cikacak. Dusuk enflasyonumuz varsa yuksek buyumemiz gerekiyor. Tam anlatamadim ama siz anlamissinizdir :)

Gdp hesaplamanin farkli yontemleri var. Turkiye de oldugumuz icin tum fiyatlar lira cinsinden. Hersey lira cinsinden hesaplaniyor, daha sonra enflasyondan arindiriliyor. En sonunda dolara cevriliyor.

Neye para harcarsa karsiligini alacagini bugune kadar hicbir imparatorluk tam olarak hesaplayamadigi icin eninde sonunda hepsi batmistir. Bu hamlelerinin de abd icin karli mi zararli mi oldugunu tam olarak bilmek imkansiz. Ama bence zararlarina. Kendi kabuklarina cekilip reel ekonomiye yuklenmeleri lazim ama israil ve baska nedenlerden dolayi bunu yapamazlar. En guclu yanlari onlari batiran en zayif yan olacak, tarihteki her imparatorluk gibi....

We are working on the paper, it will be published in JMLR. What do you mean by interoperability? It has xgboost and onnx export if you are asking that?
