The recent advancements in the field of optical and physiological signal analysis are pushing the boundaries of what is possible in clinical and telehealth applications. Researchers are increasingly focusing on developing models that can generalize across species and tasks, leveraging large-scale datasets to improve the robustness and accuracy of predictions. The field is witnessing a shift towards foundation models that can be adapted for various downstream tasks, enhancing the efficiency and effectiveness of diagnostic tools. Notably, there is a strong emphasis on creating models that are not only accurate but also computationally efficient and robust against biases, such as those related to skin tone. Additionally, the integration of multi-modal data and the use of advanced machine learning techniques, such as spatio-temporal memory networks and mixture-of-experts frameworks, are enabling more sophisticated and reliable monitoring systems. These developments are paving the way for more personalized and accessible healthcare solutions, particularly in the context of autonomous driving and continuous physiological monitoring.
