This paper deals with the problem of learning prognostic models from medical survival data, where the sole prediction of probability of event (and not its probability dependency on time) is of interest. To appropriately consider the follow-up time and censoring - both characteristic for survival data - we propose a weighting technique that lessens the impact of data from patients for which the event did not occur and have short follow-up times. A case study on prostate cancer recurrence shows that by incorporating this weighting technique the machine learning tools stand beside or even outperform modern statistical methods and may, by inducing symbolic recurrence models, provide further insight to relationships within the modeled data.
