Researchers have introduced VaLoP (Value Gradient Lookahead and Pullback), a novel method for reward-guided diffusion models. This technique improves image and action generation by addressing inaccuracies in gradient estimation, particularly at high noise levels. VaLoP achieves this by evaluating the value function at a less noisy state and pulling its gradient back to the current state, outperforming existing methods across various benchmarks and extending to robotic policy guidance.
