Hi, I have an error when I run your code:
python: /home/cys/LiteMORT/src/tree/GBRT.cpp:32: Grusoft::GBRT::GBRT(Grusoft::FeatsOnFold*, Grusoft::FeatsOnFold*, double, Grusoft::BoostingForest::MODEL, in…

I am reading through skopt's docs and it seems like there might be a typo in the description for both `gbrt_minimize` and `forest_minimize`.
**gbrt_minimize:**
```
Gradient boosted regression tr…

Are you open to expanding the functionality of GBRT to return feature importances for each class in a multinomial model, rather than just the sum importances over the entire model? E.g.,
```

- [x] add stat features into the stacker, computed over the predictions of the individual models (e.g., mean, median, max, min)
- [x] add new stack files: I would encourage model diversity here, in or…

Hi,
I'm looking for a list of methods I can use. I infer "ETPE" and "Random" are two. Any others?

We should definitely evaluate a stacking model.
Right now, we could already combine the predictions of several models of different kinds (GBRT, ET, RF, AdaBoost, DBN), which should hopefully lead to…

想问下大神,是否在特征工程中考虑正负样本不均的问题?我用GBRT跑出来的第一个模型预测都是0.8以上的score,就没有是负类的

Use stat_ model gbrt to test ETTm1 , the test result is a horizontal line。I don't know the reason for this result? Could you give me some information?
