Hi @ashokasr143,

You can divide your training dataset into two parts: train and validation. Now, train the model on train part and using that model make predictions for the validation part. Now, check the model performance on both train as well as validation part. If the performance of the model on train dataset is very high but on the validation set is poor, you can conclude that the model is overfitting.
