Question
Hi there,
I am having problem with resnet50 with 10 class classification of handwritten number from 0-9 in Nepali. My validation accuracy is very good 97% but I am having problem with the prediction. After very bad prediction on new data, I have even tried to predict with the same datasets with which I have trained the model but I can not get good prediction.
1. What is the reason of having very bad prediction of having 97% VALIDATION accuracy?
2. Which is the best classifier for 10 class classification?
3. What is the best classifier for 50 class classification?
Note: I need classifier that has good accuracy for real time data (number plate detection and prediction).
Question
I am having problem with prediction with my model trained on resnet50. I have 10 classes of Nepali numbers from (0 ...9). I have trained the model for 100 epochs with around 40,000 data . What is the issue with my model? I am having overfit? Or, the model I have used to train is just too complex for 10 class. I have also tried this model to predict on the training set but the prediction accuracy is very very poor around (10%).
Question
I want to know the difference between classifiers and when they are used. I came across naive bayes which I have found to be much appropriate with small training data set. Can anyone explain me with some clear examples and comparison how is naive bayes different than other classifiers? + How do we choose best classifiers in real examples?
