#catboost_tipsntricks CatBoost sets a learning rate by looking at the number of iterations&objects in the trainset. In today's video, Nikita explains how to use built-in interactive learning curves to tune LR & iterations and improve model performance.

@AbozeBrain @neptune_ai Thank you for that post! 😺 Worth mentioning that YetiRank was a secret weapon of Yandex Search engine since the beginning of 2010s and we made it public in one of first versions of CatBoost. And we have a great paper from Gulin et al. about it https://t.co/1bKg45NDoi

Gradient boosting methods have been proven to be an important strategy. This article with @neptune_ai aims to investigate and compare the efficiency of three gradient methods focusing primarily on @CatBoostML. https://t.co/UkMmqwtSNz

Technical notice⚠️ In the next release, we will stop publishing CatBoost artifacts for Python 2.7 & 3.5 versions. If you still need CatBoost built for 2.7 or 3.5 - you can build it from sources.
If you have any questions - contact us here, in telegram or via GitHub issues!😺

#catboost_tipsntricks In today's video, Nikita Dmitriev talks about object importance and how you can use it to detect and drop noise objects and boost the quality of your models🚀Stay tuned for the next episode! 😺 https://t.co/M0JPImLh3X

[CatBoostML @CatBoostML]

We've recorded a series of short videos to boost your CatBoost knowledge, so stay tuned😺
In today's video, Ivan Lyzhin explains why you should try different tree grow policies.

See full release notes in our github https://t.co/ZzKsvI8NA0 😺🥳

[CatBoostML @CatBoostML]

🚀🎇1.0.0��🥳
It's not only CatBoost's 100₂ anniversary but also a first major release! We upgraded the major version because CatBoost looks solid: by the last four years, CatBoost began to play a crucial role in Yandex, CERN, and many other companies.

[CatBoostML @CatBoostML]

And let us introduce the main features: fully distributed training for Apache Spark, multilabel multiclassification, big CPU training time speedup (up to 35%), improved CV speed, LogCosh loss, model size regularization fix for GPU, markdown documentation. And that's not all!

[CatBoostML @CatBoostML]

🎇We switched main url to new documentation! Old documentation would be available at https://t.co/O9evuZN38I for next two weeks. If you'll find some problems with new documentation and will need old docs available - contact us here or in telegram https://t.co/z04Av5Jaw8 🐱

[CatBoostML @CatBoostML]

We'd like to invite Russian-speaking followers to our 100₂th online birthday party. Read more and register now: https://t.co/fYpVzxsYA2
And don't worry! We are planning to translate the recorded video into English and publish links later here. Stay tuned! 😸

[CatBoostML @CatBoostML]

Good news, everyone! We've refactored CatBoost documentation and are inviting you to test it here: https://t.co/5KQlZMvMc4 And from now on documentation sources in Yandex Flavored Markdown can be easily found in our repo
https://t.co/tQb3KajMkH We are waiting for you PRs!😺

#CatBoostPoll CatBoost already supports distributed training on Apache Spark and by separate processes from CLI. If you'd like CatBoost to support your favourite framework - please vote or reply with your variant😺

[Johannes Himmelreich @jhimmelreich]

New paper: we tested how different ML methods perform on predicting administrative errors in US unemployment insurance data. Turns out: @CatBoostML is more accurate, along several measures, than every deep learning model tested. (open access for two weeks) https://t.co/Uv1Xdb4QjQ

[CatBoostML @CatBoostML]

* Fixed CatBoost training on Windows & CUDA
* Fixed incorrect worker process termination in case of exception in main process
* And fixed some annoying bugs!😸

[CatBoostML @CatBoostML]

🚀CatBoost 0.26.1 😺
News:
