Modular Score-Based Sampling Scheme for Improved Accuracy
Analysis
Key Takeaways
- •Introduces a modular scheme to simplify score-based sampling.
- •Reduces complex sampling to a sequence of 'nice' sampling problems.
- •Leverages strongly log concave (SLC) distributions.
- •Offers novel guarantees for both uni-modal and multi-modal densities.
- •Achieves high accuracy with polynomial dependence on log(1/ε) and sqrt(d).
“The modular reduction allows us to exploit any SLC sampling algorithm in order to traverse the backwards path, and we establish novel guarantees with short proofs for both uni-modal and multi-modal densities.”
