A switching Kalman filter approach to online mitigation and correction of sensor corruption for inertial navigation
[ "eess.SY", "cs.RO", "cs.SY" ]
This paper introduces a novel approach to detect and address faulty or corrupted external sensors in the context of inertial navigation by leveraging a switching Kalman Filter combined with parameter augmentation. Instead of discarding the corrupted data, the proposed method retains and processes it, running multiple o...

Towards Controllable Speech Synthesis in the Era of Large Language Models: A Survey
[ "cs.CL", "cs.AI", "cs.LG", "cs.MM", "cs.SD", "eess.AS" ]
Text-to-speech (TTS), also known as speech synthesis, is a prominent research area that aims to generate natural-sounding human speech from text. Recently, with the increasing industrial demand, TTS technologies have evolved beyond synthesizing human-like speech to enabling controllable speech generation. This includes...

VOPy: A Framework for Black-box Vector Optimization
[ "cs.LG", "stat.AP", "stat.ML" ]
We introduce VOPy, an open-source Python library designed to address black-box vector optimization, where multiple objectives must be optimized simultaneously with respect to a partial order induced by a convex cone. VOPy extends beyond traditional multi-objective optimization (MOO) tools by enabling flexible, cone-bas...
