WHEN NOISE LOWERS THE LOSS: RETHINKING LIKELIHOOD-BASED EVALUATION IN MUSIC LARGE LANGUAGE MODELS

ICASSP 2026poster

The rise of music large language models (LLMs) demands robust methods of evaluating output quality, especially in distinguishing high-quality compositions from "garbage music". Curiously, we observe that the standard cross-entropy loss -- a core training metric -- often decrease when models encounte…

Development of a 2-DOF Singularity-Free Spherical Parallel Remote Center of Motion Mechanism With Extensive Range of Motion

RA-L 2024

In this paper, we report the development of an innovative two-degrees-of-freedom (2-DOF) spherical parallel remote center of motion mechanism (SPRCMM), which can offer a wide range of movement in both DOFs without encountering singularities. To facilitate the design process, the paper briefly review

Leveraging Crowdsourced GPS Data for Road Extraction From Aerial Imagery

CVPR 2019poster

Deep learning is revolutionizing the mapping industry. Under lightweight human curation, computer has generated almost half of the roads in Thailand on Open- StreetMap (OSM) using high resolution aerial imagery. Bing maps are displaying 125 million computer generated building polygons in the U.S. Wh…
