/We looked at the first two simulated survival datasets for both the linear and non-monotonic relationships and compared the results of a FCN to a Cox regression implemented with lifelines. To compare the model fits, we looked at the C-index and log-likelihood (a larger value is better in both cases) for data in the test folds of 10 stratified K-folds and also compared these metrics to what would be obtained with the ground truth relationship (Table 1). With regards to the linear data, both the Cox model and the FCN had metrics nearly indistinguishable from the ground truth, but for the non-monotonic data, the FCN had noticeably better metrics than the Cox model.
