Position: Stop Chasing the C-index when Evaluating Survival Analysis Models

Christian Marius Lillelund, Shi-ang Qi, Russell Greiner, Christian Fischer Pedersen

ICML 2026spotlight

The current state of evaluation in survival analysis is plagued by the persistent use of evaluation metrics in ways that are misaligned with the stated modeling objective. In addition, many such evaluations are based on censoring assumptions that are left implicit or unjustified. This means that the…

Finding line spectral frequencies using the fast fourier transform

Tom Bäckström, Christian Fischer Pedersen, Johannes Fischer, Grzegorz Pietrzyk

ICASSP 2015accepted

Main-stream speech codecs are based on modelling the speech source by a linear predictor. An efficient domain for quantization and coding of this linear predictor is the line spectral frequency representation, where the predictor is encoded into an ordered set of frequencies that correspond to the r…
