Current mainstream methods treat regulatory DNA design as a property-conditioned generation task: first train a diffusion model to learn the distribution of natural sequences, then use reward fine-tuning or sampling-time guidance to push generation toward high predicted activity.

UnverifiedThe basic idea of a sequence-to-function prediction model is to take a segment of genomic DNA sequence as input and predict the molecular phenotype outputs of that region, such as gene expression levels, chromatin accessibility, histone modification states, and transcription factor binding sites.77% similarUnverifiedThe goal of regulatory DNA sequence design is to intervene in disease by precisely controlling gene expression, and it is one of the core challenges of synthetic biology and gene therapy.74% similarUnverifiedPredictive computational biology methods require models to have sufficient generalization ability, that is, to make reasonable inferences about new cell types and new tissue environments outside the training data; this requires models not only to fit the data but also to learn the underlying causal mechanisms.72% similarUnverifiedThe usage-aware framework transforms the experimental design problem from classical combinatorial optimization or greedy selection into a sequential decision-making problem, which can be solved with reinforcement learning or gradient-based policy optimization methods.72% similarUnverifiedDiscrete diffusion models specifically handle discrete data (such as amino acid sequences, DNA sequences, or text); the forward process typically employs a masking mechanism that replaces certain positions in the sequence with [MASK] tokens, which the model progressively predicts and restores during the reverse process.69% similar
