DyRA: Dynamic Residual Approximation for Efficient Matrix Multiplication in DNNs

DyRA introduces a dynamic, input‑adaptive approach to improve matrix multiplication in deep neural networks by correcting residual output errors during inference. Unlike prior methods that approximate only the weight matrices, DyRA directly optimizes low‑rank factors of the output, combining efficient structured computation with input‑dependent correction. Experiments across vision, speech, and language models show that DyRA consistently enhances the accuracy‑efficiency trade‑off, achieving a 1.5× GPU speedup for DINOv3 while reducing accuracy loss more than threefold compared to weight‑only baselines.

FAME: An FPGA-Based Platform for Approximate Multipliers Evaluation with Pattern-Guided DNN Retraining

FAME is an FPGA-based platform that evaluates approximate multipliers directly in hardware, eliminating slow CPU/GPU LUT emulation and reducing evaluation time for DNN inference. It also introduces a pattern-guided retraining method that uses multiplier-specific patterns to recover accuracy losses. Experiments on ResNet‑18 and MobileNetV2 over ImageNet show up to 3.47× faster multiplier evaluation and a 65.5% accuracy improvement over prior retraining approaches.

MONA: Muon Optimizer with Nesterov Acceleration for Scalable Language Model Training

MONA is a new optimizer that extends the Muon optimizer by adding a Nesterov‑style acceleration term derived from an exponential moving average of gradient differences. The paper provides a convergence analysis showing that this term offers curvature‑aware corrections while maintaining Muon’s spectral‑norm regularization. Empirical results demonstrate that MONA outperforms both Muon and AdamW on Mixture‑of‑Experts pretraining across models ranging from 1 B to 68 B parameters, and achieves state‑of‑the‑art performance on downstream benchmarks after fine‑tuning the largest model.
