[BUG] Quantile Mode seems to behave like classification in some bad ways #3545

Closed SamuelGabriel closed 11 months ago

Hi There,

Nice to have seen some of you at Automl-conf and thanks for this package.

I run into the following errors when using quantile (@jwmueller). I give a little script you can copy into ipython to see it for yourself below. It happens on any kind of dataset for me.

I run autogluon like this:

import pandas as pd
import numpy as np
from autogluon.tabular import TabularPredictor
from sklearn.datasets import make_regression

# Generate synthetic regression data
x, y = make_regression(n_samples=1000, n_features=10, noise=0.1, random_state=42)

# Create a DataFrame
train_data = pd.DataFrame(np.concatenate([x, y[:, np.newaxis]], 1))
train_data.columns = [f"feature_{i}" for i in range(x.shape[1])] + ["target"]

# Create TabularPredictor
predictor = TabularPredictor(
            label=train_data.columns[-1],
            problem_type='quantile',
            quantile_levels=[.1, .5, .9],
        ).fit(
            train_data=train_data,
            time_limit=300,
            presets=["best_quality"]
        )

# Make predictions (example)
test_data = pd.DataFrame(np.random.randn(5, 10), columns=[f"feature_{i}" for i in range(10)])
predictions = predictor.predict(test_data)

print(predictions)

Hi, thank you for the bug report!

@Innixma I was able to reproduce the bug locally. It seems that the root of the problem is this change that accidentally removed the code for ensuring that only models listed in DEFAULT_QUANTILE_MODEL can be trained when problem_type==QUANTILE. We need to introduce this change and, probably, add tests that would catch similar problems in the future.
