Abstract Automatic segmentation of breast tumors in ultrasound images can assist physicians in making accurate and effective decisions. However, fully supervised learning methods typically require large amounts of pixel-level annotations, which are often difficult to obtain. Weakly supervised segmentation using image-level labels offers a promising alternative, but generating high-quality pseudo-segmentation labels remains a major challenge.

ABSTRACT Understanding older adults’ music preferences is vital for their active aging, yet little research exists in the Chinese context.

Some seniors showed enthusiasm for traditional Chinese instruments and passionate styles, while others had low engagement across all dimensions.
