Figure. Predictor-guided generator optimization enables gene-specific navigation of the regulatory sequence-expression landscape. T-distributed stochastic neighbor embedding (t-SNE) mapping of the input latent subspaces that produce novel sequence variants spanning ~6 orders of magnitude of gene expression (colored and black dots), uncovered using the predictor-guided generator optimization. Black dots represent selections of 10 sequence variants per each of the 4 expression groups covering a 4 order-of-magnitude range of predicted expression levels from TPM ~10 to ~10,000.
Arrowsheads were incorrectly rendered and are missing in schematic figures 1a,d, 3a & 6e. The correct panels are available in the docs folder.
