Pneumonia Detection
Pneumonia Detection using machine learning.
Training was done in colab:

Data
I uploaded my dataset to kaggle I used a modified version of this dataset from kaggle. Instead of NORMAL and PNEUMONIA I split the PNEUMONIA dataset to BACTERIAL PNUEMONIA and VIRAL PNEUMONIA. This way the data is more evenly distributed and I can distinguish between viral and bacterial pneumonia. I also combined the validation dataset with the test dataset because the validation dataset only had 8 images per class.
This is the resulting distribution:
Processing and Augmentation
I resized the images to 150x150 and because some images already were grayscale I also transformed all the images to grayscale.
Additionaly I applied the following transformations/augmentations on the training data:
transforms.Resize((150, 150)),
transforms.Grayscale(),
transforms.ToTensor(),
transforms.RandomHorizontalFlip(),
transforms.RandomVerticalFlip(),
transforms.RandomRotation(45)
and those transformations on the test data:
transforms.Resize((150, 150)),
transforms.Grayscale(),
transforms.ToTensor(),
This is the resulting data:
I also used one-hot encoding for the labels!

Visualization using Streamlit
The webapp is not hosted because the model is too large. I'd have to host it on a server. This is just to visualize.
