Multimodal Machine Learning in Image-Based and Clinical Biomedicine: Survey and Prospects
It addresses the integration of multimodal ML into biomedical practice for healthcare providers, but is incremental as it is a survey paper.
This survey examines the current state and challenges of multimodal machine learning in medical image analysis and clinical decision support, highlighting its transformative potential for clinical predictions and the need for principled assessments and practical implementation.
Machine learning (ML) applications in medical artificial intelligence (AI) systems have shifted from traditional and statistical methods to increasing application of deep learning models. This survey navigates the current landscape of multimodal ML, focusing on its profound impact on medical image analysis and clinical decision support systems. Emphasizing challenges and innovations in addressing multimodal representation, fusion, translation, alignment, and co-learning, the paper explores the transformative potential of multimodal models for clinical predictions. It also highlights the need for principled assessments and practical implementation of such models, bringing attention to the dynamics between decision support systems and healthcare providers and personnel. Despite advancements, challenges such as data biases and the scarcity of "big data" in many biomedical domains persist. We conclude with a discussion on principled innovation and collaborative efforts to further the mission of seamless integration of multimodal ML models into biomedical practice.
