Lightgbm classifier code

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:

WebSep 3, 2024 · There is a simple formula given in LGBM documentation - the maximum limit to num_leaves should be 2^ (max_depth). This means the optimal value for num_leaves lies within the range (2^3, 2^12) or (8, 4096). However, num_leaves impacts the learning in LGBM more than max_depth.
