I trained my model, but it's performing too well on validation — could this be data leakage? How do I check for that?

4

I’m seeing 98–99% accuracy on my validation set, but when I test on truly unseen data, the performance drops significantly. Suspecting some leakage but not sure where it’s happening

What's the best way to normalize data without leaking info from the test set into the training process?

5

I used StandardScaler on the entire dataset before splitting, and later realized that might be wrong. How should I handle scaling correctly to avoid leakage?

I'm dealing with an imbalanced dataset. What methods have you used to address this issue?

4

Imbalanced datasets can skew model performance. Share techniques like resampling or using different evaluation metrics that have worked for you.

Anybody knows good methods to debug autograd issues in dynamic graphs, especially with JAX or PyTorch?

6

I’ve been running into unexpected gradients or zero gradients in some layers, and it’s been tricky to trace where things go wrong. Any tips, tools, or workflows that help identify and fix these problems would be really appreciated!

My training loss on my transformer model just won’t settle down, it keeps jumping all over the place. Could this be a learning rate issue or something else?

5

I’ve tried lowering the learning rate but no luck. Wondering if batch size or tokenization might be causing this.
