getting ready for a beta launch. model is solid but not perfect, so now it’s time to get real feedback. if you know someone in the medical field who wants to test it, hit me up

finally tested on some mri scans outside the dataset. model did alright but struggled with some blurry ones. might need to train it with lower-quality images too so it doesn’t freak out

back to work confusion matrix results are in. glioma and pituitary detection are solid but no-tumor cases still a bit off. probably need to rebalance the dataset or adjust loss function github.com/qqxnsx/bs-ai/t…

ran the model on test data and it’s doing decent, but still getting some false positives on no-tumor cases. might need to tweak thresholds or add more samples for balance

built a way to actually see what the model is focusing on with grad-cam. now we can tell if it's looking at the right spots in the mri or just guessing based on weird noise

added data augmentation so the model doesn’t just memorize stuff. rotating, flipping, and shifting mri scans should make it handle real-world cases better. training again now github.com/qqxnsx/bs-ai/t…

decided to use transfer learning with vgg16. saves time and gives the model a solid starting point instead of training from scratch. accuracy already looking better github.com/qqxnsx/bs-ai/t…

swapped out some layers in the cnn, now it's picking up tumor patterns more clearly. glioma and meningioma detection looking way better. still gotta test on more real-world data tho github.com/qqxnsx/bs-ai/t…
