Привет всем! Вышeл CatBoost 0.26.
New features#972. Add model evaluation on GPU. Thanks to
@rakalexandra.
Support Langevin on GPU
Save class labels to models in cross validation
#1524. Return models after CV. Thanks to
@vklyukin[Python] #766. Add CatBoostRanker & pool.get_group_id_hash() for ranking. Thanks to
@AnnaAraslanova#262. Make CatBoost widget work in jupyter lab. Thanks to
@Dm17r1y[GPU only] Allow to add exponent to score aggregation function
Allow to specify threshold parameter for binary classification model. Thanks to
@Keksozavr.
[C Model API] #503. Allow to specify prediction type.
[C Model API] #1201. Get predictions for a specific class.
Breaking changes#1628. Use CUDA 11 by default. CatBoost GPU now requires Linux x86_64 Driver Version >= 450.51.06 Windows x86_64 Driver Version >= 451.82.
Losses and metricsAdd MRR and ERR metrics on CPU.
Add LambdaMart loss.
#1557. Add survivalAFT base logic. Thanks to
@blatr.
#1286. Add Cox Proportional Hazards Loss. Thanks to
@fibersel.
#1595. Provide object-oriented interface for setting up metric parameters. Thanks to @ks-korovina.
Change default YetiRank decay to 0.85 for better quality.
Python package#1372. Custom logging stream in python package. Thanks to
@DianaArapova.
#1304. Callback after iteration functionality. Thanks to
@qoter.
R package#251. Train parameter synonyms. Thanks to

@ebalukova.
Speedups[Python] Speed up custom metrics and objectives with numba (if available)
[Python] #1710. Large speedup for cv dataset splitting by sklearn splitter
OtherUse Exact leaves estimation method as default on GPU
[Spark] #1632. Update version of Scala 2.11 for security reasons.
[Python] #1695. Explicitly specify WHEEL 'Root-Is-Purelib' value
BugfixesFix default projection dimension for embeddings
Fix use_weights for some eval_metrics on GPU - use_weights=False is always respected now
[Spark] #1649. The earlyStoppingRounds parameter is not recognized
[Spark] #1650. Error when using the autoClassWeights parameter
[Spark] #1651. Error about "Auto-stop PValue" when using odType "Iter" and odWait
