Hey, Am I right that today will be published version 1.0.5 with m1 support? Thanks

When doing multiregression, i.e. multiple target values in catboost regression, is there a difference between using one model per target value vs using one model for all targe...

Dear team, I'm working on a project in which i have an imbalance dataset, To train a model i did the train test split based on y, did the stratified cross validation for mod...

Hi! I'm trying to distill a NN model into a catboost model. For this I need to provide class prediction logits as targets and use crossentropy as the loss. I'm not sure how ...

Clickbait headline: Don't try to tune the learning rate or the number of iterations... 😸😸😸 But seriously, If overfit or underfit bothers you that much, just watch our new vi...

Hi folks, I was training a classifier model with some custom training params - feature_weights and per_float_feature_quantization. Does anyone know if this is supported in c++...

Hi there, I wanted to ask: is there a way to include an adjacency matrix as a feature in CatBoost? I want to use CatBoost rather than a graph neural network as I would also li...

Hi all, very excited to join this group. I have been a lgbm user for a long time and amazed at what catboost is capable of doing. Catboost gets very close to my tuned lgbm mod...

🤓 Do you know that sometimes training or applying models on CPU may be faster than GPU? In new short video @kizill explains how it is possible: https://youtu.be/VrtSrRkO9EI?t=...

Hi, about CatBoostRegressor and prediction_type='Probability' pred = model.predict(x_eval, prediction_type='Probability') dfpred = pd.DataFrame(pred, columns=["col1", "col2"...

hey guys, I met a problem that always catboost account into segfaults at 2nd trial in optuna study task. does anyone have the same problem?

In the new Release it says that Text Features are now supported in the R Version. But the load_pool function has no mention of Text Features. How can Text Features be used th...

Hi everyone, Is it possible to kill/terminate a learning/training process on Python? My learning function is running background and somehow I have to kill it from command lin...

Hi, I wanted to ask about select_features. The function input ‘num_of_features_to_select’ is a required parameter. There is any way to select the best set of features and not...

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...

Hi everybody. I need to use a custom metric but I keep getting this error and couldn’t find any solution to that on the internet. What are your suggestions? Thanks in advance.

This looks like a network connectivity issue. Is network communication between Spark driver and executor nodes allowed on all ports?

Привет, нужна помощь. Обучаю кота предсказыванию уникального индекса таблицы БД. Регресиия раньше хорошо справлялась: CatBoostRegressor(iterations=1000, depth=6, learning_rate...

Also for the embedding Features can they be combined with Regression or only with classification ? Will there be more information on how this works ?

Hello, how do we interpret the leaf values for binary for a trend prediction. Do we need to sum the respective branch values and take sigmoid for actual predictions?
