Biased Model

[ParthMandaliya]

I plotted the confusion matrix with your model with test loader.

Model is biased it always outputs 0 regardless of input.

Thank you for reporting the issue, the model was trained in the preliminary test without finetuning. I did not sample and balance the data before, which cause low F1 score and too many False Positive. I will retrain the model and update the repo.

hey can you provide the updated repo please !!! like i m getting the model biased and there is no balance in the data as well. Please employ all of them and make the updated repo

I've trained the model using the provided code, but I'm getting a very low AUC score (around 0.5). Although the accuracy is high, the model is heavily biased due to the imbalanced data, predicting mostly non-fraudulent nodes.

I've been experimenting with different modifications to improve performance, but so far, I haven't been able to push the AUC beyond 0.7. Has anyone else solved this issue?
