Identical logit values for 6-year lung cancer risk prediction on CT-RATE and NLST dataset
Thank you for sharing your excellent work!
I applied your repository exactly as it is to the CT-RATE and NLST dataset. However, I noticed something strange and had a question. The predicted lung cancer risk values for the 6-year period are outputting almost identical logit values for all 6 years within each sample.
Here are the results from ensemble.csv:
