What is Early stopping?Early stopping kya hai?

🧸 Think of it likeAise samjho

Like taking the cake out of the oven when it's perfectly done, instead of baking longer and burning it.Cake ko perfect banne pe oven se nikaal lena, zyada der bake karke jalaane ki jagah.

📘 ExplainedVistaar se

As training continues, training loss keeps falling but validation loss eventually rises as the model starts memorising. Early stopping watches validation performance and keeps the best checkpoint. It's standard for gradient boosting and neural networks.Training chalti rahe to training loss girta rehta hai par aakhir mein validation loss badhne lagta hai kyunki model ratne lagta hai. Early stopping validation performance dekhta hai aur best checkpoint rakhta hai. Gradient boosting aur neural networks mein standard hai.

💡 Real exampleAsli example

Validation loss is lowest at round 240, so training stops at 260 and keeps round 240.Validation loss round 240 pe sabse kam hai, to training 260 pe rukti hai aur round 240 rakhti hai.

• OverfittingWhen a model memorises its training data, including noise, and does badly on new data.Jab model training data ko, noise samet, ratt leta hai aur naye data pe kharab karta hai.
• Validation setData used while building a model to compare options and tune settings.Model banate waqt options compare karne aur settings tune karne ke liye data.
• EpochOne full pass of the training algorithm over the entire training dataset.Training algorithm ka poore training dataset pe ek poora chakkar.
