Abstract: A method includes accessing a training dataset having multiple samples, where each sample includes a data point for each of multiple modalities. The method also includes generating, using a first encoder associated with a first modality of the multiple modalities, first modality embeddings for data points of the first modality in the training dataset. The method further includes, for each first modality embedding, determining a similarity metric to other first modality embeddings. The method also includes generating, using a second encoder associated with a second modality of the multiple modalities, second modality embeddings for data points of the second modality in the training dataset. In addition, the method includes training the second encoder based on a contrastive loss function to align the first modality embeddings and the second modality embeddings from different samples of the training dataset, where the contrastive loss function is weighed using the similarity metrics.

Abstract: A method for performing cuffless blood pressure (BP) measurement, including: obtaining a first physiological signal and a second physiological signal associated with a user; providing the first physiological signal as an input to a first transformer model; providing the second physiological signal as an input to a second transformer model; providing an output of the first transformer model and an output of the second transformer model as inputs to a third transformer model; providing an output of the third transformer model to at least one BP estimation model; and generating an estimated BP value corresponding to the first physiological signal and the second physiological signal based on an output of the at least one BP estimation model
