Manifold-Aware General Coded Computing for Straggler-Resilient Distributed Computing

The paper introduces a manifold‑aware encoding strategy for general coded computing (GCC) that preserves the intrinsic low‑dimensional structure of high‑dimensional datasets. Unlike traditional coded‑computing designs that ignore data structure, this approach generates coded samples that follow the natural manifold of the data, inspired by graph‑based manifold learning. Experiments on neural network inference and high‑dimensional polynomial evaluation show that the new strategy consistently and significantly reduces mean squared recovery error under straggling compared with standard GCC.

GraphK: Variable-Size Graph Generation with Efficient Edge Construction

GraphK introduces an encoder‑sampler‑decoder framework that generates variable‑size graphs efficiently. It learns permutation‑invariant latent representations and samples new node embeddings via maximum likelihood, enabling both upscaling and downscaling of graph size. Edge construction uses KDTree‑based top‑k neighbor search in latent space, reducing computational cost while capturing graph properties.

Towards Practical Compression of 3D Gaussian Splatting

The paper introduces COSA-GS, a new compression method for 3D Gaussian Splatting that avoids spatial aggregation by using anchor-wise causal factorization. It builds a compact learnable anchor latent from geometry context and fuses it with the geometry context to create an anchor context for attribute coding, employing only linear transformations and activations. The method is trained with rate–distortion optimization, adaptive Gaussian pruning, and quantization-aware training to ensure bit‑exact entropy decoding across platforms, achieving state‑of‑the‑art compression performance with fast, consistent cross‑platform decoding.

Lightweight Adaptive ReduNet via Hyperspherical Manifold Learning

The paper introduces LA-ReduNet, a lightweight adaptive version of the ReduNet neural network that uses hyperspherical manifold learning and adaptive step sizes to reduce the number of layers needed for the maximal coding rate reduction (MCR$^2$) objective to stabilize. By refining the layer‑wise update rule, LA-ReduNet achieves comparable classification accuracy while requiring far fewer layers and significantly less parameter storage—about 1/29 of the unfolded ReduNet module under the tested settings.
