PAX-TS: Model-agnostic multi-granular explanations for time series forecasting via localized perturbations
Time series forecasting has seen considerable improvement during the last years, with transformer models and large language models driving advancements of the state of the art. Modern forecasting models are generally opaque and do not provide explanations for their forecasts, while well-known post-hoc explainability methods like LIME are not suitable for the forecasting context. We propose PAX-TS, a model-agnostic post-hoc algorithm to explain time series forecasting models and their forecasts.…

Debugging domain creation
Executive Summary: OpenNebula environment grown over 12 years running OpenNebula v5.2, upgrading host OS breaks initial domain creation. Live migration works! Versions of the related components and OS (frontend, hypervisors, VMs): CentOS7 with qemu-kvm on 30 Intel-cpu (Supermicro) hosts. some hosts upgraded to Alma9, fully updated. VMs a mix of versions of FreeBSD, CentOS, Alma, Ubuntu, Windows. CentOS7 hosts have been operating properly for many years. Some Alma9 hosts are new, others are…
