I was inspired by to re-train the ResNet v4 model on a prostate cancer MRI data set from

What it does

Open the app and point your camera to a fullscreen image of an MRI scan of prostate cancer on your computer screen (example images It will classify the image into one of 5 histological scores, showing the confidence probabilities associated with each of the scores (

How I built it

I downloaded the data set and converted the DICOM MRI scans to JPEG files. In python, I trained the Inception tensorflow model with this data set. Since the project was very large, I optimized the algorithm and associated files for mobile.

Challenges I ran into

Training the model with 10000+ images on CPU took very long. There are significant limitations as to the efficacy of the results as I did not try to optimize the hyperparameters.

Accomplishments that I'm proud of

I built this in 20 hours of work since last night and learned a lot the whole way.

What I learned

Training a deep neural network with a large data set requires significant computation power. I learned that this product would work better if I had worked with a team. Since I heard about this competition only a few days ago and started working on it last night, I did not have the input of other minds nor is it a product ready for real medical use.

What's next for Prostate Cancer Detector

Get a team together, rebuild and retrain the model, rigorously test it, consult with doctors and pathologists at UCSF, optimize, get user feedback.
