How can I improve my validation techniques in machine learning?
Improving validation techniques can enhance model performance. Are you using cross-validation or any specific methods?
I'm currently using k-fold cross-validation, but I'm not sure if it's enough.
K-fold is a great start! You might also consider techniques like stratified sampling or using a validation set for better insights.
What is stratified sampling, and how does it help?
Stratified sampling ensures that each class is proportionally represented in both training and validation sets, improving model reliability.
That sounds useful! Are there any tools you recommend for implementing these techniques?
Yes! Libraries like Scikit-learn in Python offer built-in functions for k-fold and stratified sampling, making implementation easier.
