Wrong output for custom images #7

Open liuhuihuii opened 5 years ago

liuhuihuii commented 5 years ago

I solved the problem with the image size last night and I should thank you for that, however, after I trained the network for 24 epochs, the prediction of custom images are still far from correct. The percentage of each label it gives for custom images is around 25%, while testing random images from the data set gives very definite answer (50% for one label). Is it because of overfitting or not enough epochs? Is there any advice to improve the correctness for custom images?

I originally set the epoch count to 10, maybe try that

But when I use your pretrianed mode 'my_model3.h5' t to predict my own cunstom image named 'InvasiveC2_2048x1536.jpg' ,then output is like: Average from all crops

Benign : 20.6134% InSitu : 31.7345% Invasive : 20.0719% Normal : 27.5802%

Not sure why, are these from your images?

I downloaded them from the internet. Maybe they are not labeled correctly, but I trust wiki anyways

For example, this image is from Wikipedia and it says normal on the site the output is Benign : 29.1999% InSitu : 21.6953% Invasive : 26.8959% Normal : 22.2089% all percentage is close to 25% normalc1_2048x1536

Maybe there is some mismatch in the image formats then, I'm not sure what's wrong
