WebApr 6, 2024 · The loss function adopts MSE. The LGB model (LightGBM) sets the maximum depth to four, the learning rate to 0.05, and the number of leaf nodes to seven. It generates probabilistic classification and classifies the test data as fraudulent with probability p, 0 ≤ p ≤ 1. From the above text, we used the smote algorithm to perform data resampling. Web5 hours ago · I am currently trying to perform LightGBM Probabilities calibration with custom cross-entropy score and loss function for a binary classification problem. My issue is related to the custom cross-entropy that leads to incompatibility with CalibratedClassifierCV where I got the following error:
