In this work, we present a new model-agnostic approach to predicting community compositions using compressive sensing. Working on a community-structure landscape, we discovered a sparse representation of the community compositions. We then leveraged this sparsity to predict community compositions from limited data by applying techniques from compressive sensing. By sampling just ~1% of all possible communities, we recovered community compositions with high accuracy on synthetic datasets. We demonstrate the usefulness of this method in diverse real-world settings by applying it to four experimental datasets, with two datasets associated with soil microbiome, one relevant to the fruit fly gut microbiome, and one consisting of species relevant to the human gut.
