SwiftExplorer: Training-free Diffusion Model Alignment with Swift Diversity Exploration

SwiftExplorer is proposed, a plugin that mitigates distribution collapse caused by excessive diversity loss and reduces compute costs, and adopts an Inheritance-Restart exploration mechanism to avoid early convergence, while exploration also increases the likelihood of high-reward trajectories.

REF-CIM: A 40-nm Non-Ideality Tolerant and Energy Efficient RRAM Compute-in-Memory Macro With Configurable Precision for Edge AI

Compute-in-Memory (CIM) based on resistive random access memory (RRAM) offers significant advantages in energy efficiency and parallelism, making it a promising solution for accelerating neural networks. However, the computational accuracy, energy efficiency, and flexibility of current CIM chips are still challenged by...

Explore or Converge? Stage-Guided Per-Step Optimization for Diffusion Models

Stage-Guided Per-Step Optimization (SGPO) is proposed for diffusion models, which jointly leverages signal-to-noise ratio and semantic changes to identify generation stages and adaptively assign stage-specific objectives.

HEMERA: A Heterogeneous Memory-Centric Accelerator with Recursive Dataflow for Edge-Constrained State-Space-Duality Models Inference

HEMERA is presented, a heterogeneous memory-centric accelerator for efficient Mamba-2 inference that reformulates the matrix-form SSD computation into an algebraically equivalent streaming-recursive dataflow that avoids quadratic intermediate storage while preserving the original computation.

PAST: Prompt-Adaptive Sampling Termination for Efficient Diffusion Model

PAST is proposed, which provides differentiated rewards while adaptively regulating training episode length by jointly perceiving denoising progress and prompt difficulty and establishes a dual adaptive coordination mechanism that balances the extrinsic and intrinsic rewards.
