How do Ordered Target Statistics work for CatBoost?
This question follows closely this paper .
I'm trying to fully understand how Ordered Target Statistics (TS) (for CatBoost) works. E.g. the CatBoost algorithm uses this method to group categorical features through estimatation of numerical values…

Is Regularization a must for target-based encoders?
The most stable and accurate Categorical encoders are target-based encoders. Target encoding is the process of replacing a categorical value with the mean of the target variable. From the Source 4. Regularization is a must for target-based…

Target encoding for survival analysis
I was wondering if it is appropriate to use target encoding (Catboost) for a survival analysis problem (most likely I will approach it first with Cox Proportional Hazards). I have several variables with high cardinality, some of them have similar…

What should i do with this kind of data? (price from the ads and actual price)
There are two subsamples in the dataset - on one the target is real(valid), and on the other it is approximate (I don't know how it differs yet, on one sample the real price of an apartment, and on the other the price from ads, you need to predict…

Target encoding categorical variables when population means are known
Target encoding (aka mean or categorical encoding) converts a categorical independent variable to a continuous response for use in predictive modelling. In its most basic form, it does this by calculating the mean of the continuous dependent…
