Simultaneous profiling transcriptomic and chromatin accessibility information in the same individual cells offers an unprecedented resolution to understand cell states. However, computationally effective methods for the integration of these inherent sparse and heterogeneous data are lacking. Here, we present a single-cell multimodal variational autoencoder (scMVAE) model, which combines three types of joint-learning strategies with a probabilistic Gaussian Mixture Model (GMM) to learn the joint latent features that accurately represent these multi-layer profiles. Studies on both simulated datasets and real datasets demonstrate that it has more preferable capability (a) dissecting cellular heterogeneity in the joint-learning space, (b) denoising and imputing data, and (c) constructing the association between multi-layer omics data, which can be used for understanding transcriptional regulatory mechanisms. |
