WebAsep Fajar Firmansyah.Thanks for answering my question. The behavior here is a bit strange. I see that accuracy of validation data is better in every epoch as compared to training but at the same ... WebFluctuating validation accuracy. I am learning a CNN model for dog breed classification on the stanford dog set. I use 5 classes for now (pc reasons). I am fitting the model via a ImageDataGenerator, and validate it with another. The problem is the validation accuracy (which i can see every epoch) differs very much.
WebNov 27, 2024 · The current "best practice" is to make three subsets of the dataset: training, validation, and "test". When you are happy with the model, try it out on the "test" dataset. The resulting accuracy should be close to the validation dataset. If the two diverge, there is something basic wrong with the model or the data. Cheers, Lance Norskog.
