“…To leverage the unlabelled bio-signals, like [16], Thin- X-ray [133,149] Ultrasound [132,150] Segmentation Abdnomial [44,48,153,155] Ultrasound [157,[159][160][161] Comprehensive [163,164,167] Survival prediction WSI [58,60,171,172,174] sungnoen et al [35] designed auto-encoder networks training bio-signal representations and then clustering features. In recent years, the emerging family of self-supervised (contrastive) learning methods has been applied to bio-signals data [186-192, 199, 202-204] .…”
