Kullback-Leibler-Based Discrete Failure Time Models for Integration of Published Prediction Models with New Time-To-Event Dataset

2021 · arXiv (Cornell University)

Prediction of time-to-event data often suffers from rare event rates, small sample sizes, high dimensionality and low signal-to-noise ratios. Incorporating published prediction models from large-scale studies is expected to improve the performance of prognosis prediction …

Distributed Key Derivation for Multi-Party Management of Blockchain Digital Assets

2023

The current Single-User Key Derivation (SKD) caters to individual management of blockchain’s tree-structured assets but falls short for threshold signatures aimed at multi-party control of blockchain assets. We introduce a Distributed Key Derivation (DKD) for …
