The invention belongs to the technical field of single
cell data processing, and particularly relates to a single
cell time sequence data simulation and completion method and
system. The method comprises the following steps that interpolation is carried out on hidden
space vector representation in a time starting point and end point single
cell matrix variational auto-
encoder (VAE) model, then interpolation is carried out on the two vectors in a hidden space, and a middle time point hidden
space vector is generated; finally, the vectors are reduced into a
gene expression matrix through a decoder, so that missing or unobserved single cell data at the middle moment in the
time sequence are simulated, the single cell data in the
time sequence can be simulated through the method, and therefore the continuous change of the
cell state can be deduced and complemented; the method is suitable for single cell level pedigree reconstruction and
trajectory analysis in dynamic biological processes such as development, aging and
disease progression, and has high biological interpretation value and practical application significance.
