Hi, I am trying to generate confidence intervals for the below sample data. I am using RandomForestRegressor with bootstrapping enabled. X_train shape (270, 7) [[ 12. 20. 1. ... 300....

Overflow errors

5

When using `random_forest_error()` with a dataset in which the features range between 0 and 1 and of datatype `float64`, I get a bunch of overflow errors like so: ``` /Users/erictaw/forest-confidence-interval/forestci/calibration.py:86:...

On a toy problem, in which I am using Random Forests + ForestCI to prototype some ideas, I will randomly get NaNs in the `V_IJ` estimates. This toy problem is...

Benchmarking confidence intervals

For my dataset, I tried correlating the CIs to absolute error on the test set, and didn't find a relationship. I do get a relationship if I use the standard...

I’m looking at using random forest regressors to perform hyperparameter tuning in a Bayesian optimization setup. While you can use the upper confidence bound to explore your state space, Thompson...

Sum taken over wrong axis

Hi there, I believe the centered predictions are being computed incorrectly. Line 278 in `forestci.py` takes the average over the _predictions_, as opposed to the trees. The resulting shape of...
