Latent Diffusion With Topology-Preserving Conditioning for Structure-Aware Data Generation.

Experiments show that TopoSegDiff produces more realistic and structurally faithful image-mask pairs, reduces topology inconsistency, and consistently improves downstream segmentation performance when used for synthetic augmentation, which support topology-preserving conditioning as an effective route toward more relia...

SMLDR: Spectral Memory Learner with Dual-Retrieval for Time Series Forecasting

This paper re-examines frequency-domain modeling from the perspective of spectral non-identifiability and proposes a Spectral Memory Learner with Dual Retrieval (SMLDR) for time series forecasting, which represents periodic components as reusable spectral prototypes stored in learnable memory.

GraTAG: Production AI Search via Graph-Based Query Decomposition and Triplet Aligned Generation with Rich Multimodal Representations

Traditional search engines struggle to synthesize fragmented information for complex queries, while generative AI search engines face challenges in relevance, comprehensiveness, and presentation. To address these limitations, we introduce Xinyu AI Search, a novel system that incorporates a query-decomposition graph to...
