H3DNAS: Hardware-Aware ONNX-Native 3D Point Cloud Model Compression

Read the original on arXiv Machine Learning →

H3DNAS is a hardware‑aware compression framework that operates directly on ONNX computational graphs, eliminating the need for original source code or gradient access. It introduces a Channel Dependency Graph to classify operators and compute a provable compression ceiling, and employs a two‑stage hierarchical search that prunes architectures via L1‑importance channel selection and applies GhostConv mutations to Pareto‑optimal candidates. Applied to 3D point‑cloud models on the ModelNet40 dataset, H3DNAS reduces parameters by up to 65.5% and achieves significant inference speedups with negligible accuracy loss.

Sigma-Branch: Hierarchical Single-Path Network Reconstruction for Dynamic Inference with Reduced Active Parameters

arXiv:2606. 09924v1 Announce Type: cross Abstract: Deploying deep neural networks on memory-constrained edge accelerators is bottlenecked by per-inference off-chip weight transfer rather than computation: the dense network cannot be retained on-chip, and every parameter must be loaded for every input.

Tensor-Accelerated Eager Multi-Resolution Grids for Evolving Large-Scale Substrates

The paper introduces EMR‑HyperNEAT, an eager multi‑resolution grid approach that replaces the recursive quadtree subdivision of ES‑HyperNEAT with a parallelizable evaluation of all grid positions followed by a variance‑based filter. This reformulation removes sequential dependencies, enabling efficient batching across cores and population members, and reduces computational complexity from <O(4^D)> to <O(4^D/P)>. Experiments show 12–34× GPU speedups at depths 5–7 on XOR and higher solve rates across benchmarks.
