I do not care if you say it is not impressive results.. what is impressive is your efforts and new thought you put into this article.. WELL DONE!!

Thank you, I'm glad that this aroused interest.

 

Hi Alex,

Good work!!! I plan to experiment based on your code. One question, do you normalize the predictors in your code somewhere (i had a quick look inside, but didn't notice), or it is done inside CatBoost? Some say normalization is a must for ML.

best regards

Hello. Normalization is required for neural networks. Tree-based models do not require normalization, since the partitioning of predictors occurs independently in the range from minus infinity to plus infinity, conditionally.

 

Hi,

Thanks for the interesting work and article. I tried to repeat your work but when i start CB_Calc_Svod script it stops with memory leakage. model_mqh folder is not created. CB_svod.csv is generated but strangely my lines of the test and exam balans are filled with 0. Do you know how i can solve this issue? Thanks

Hello. Did you run all the files after training?

  • _02_Rezultat_Exam.bat - settings for recording classification by the examination sample models
  • _02_Rezultat_test.bat - settings for recording classification by the testing sample models
  • _02_Rezultat_Train.bat — settings for recording classification by the learning sample models
  • _03_Metrik_Exam.bat — settings for recording the metrics of each tree of the examination sample models
  • _03_Metrik_Test.bat — settings for recording the metrics of each tree of the testing sample models
  • _03_Metrik_Train.bat — settings for recording the metrics of each tree of the training sample models
  • _04_Analiz_Exam.bat — settings for recording the assessment of predictor importance for the examination sample models
  • _04_Analiz_Test.bat — settings for recording the assessment of predictor importance for the testing sample models
  • _04_Analiz_Train.bat — settings for recording the assessment of predictor importance for the training sample models

Yes, I even waited after each to finish (first I started at the same time, as it was written in the article)

Show a screenshot of the directory with the model - you need to make sure that all the necessary files are there.

Please upload the log after the CB_Calc_Svod script is running.
