FFSlim: An Efficient and Lightweight Format for Multi-modal Data Storage and Retrieval

With the rapid expansion of large-scale media-text corpora, multi-modal datasets increasingly require efficient storage and retrieval. Existing formats such as Files, TDP, and FFRecord work adequately for uni-modal data but expose fundamental limitations in multi-modal settings, including storage redundancy, massive sm...

HBF-Sim: An Extensible HBF Simulator for Large-scale GPU Memory Systems

High-bandwidth flash (HBF) is introduced to address the memory wall, which can co-package a dense NAND stack with the GPU, targeting the performance gap between near-accelerator bandwidth and flash density. HBF, however, is neither a large HBM nor a fast NVMe SSD. Its usable bandwidth depends on how GPU cache-line requ...

A Multimodal Graph Framework for News Credibility Assessment and Propagation-Level Prediction

A multimodal framework that produces a credibility classification and a propagation-level prediction within a single processing pipeline is evaluated that combines frozen RoBERTa features, engineered interaction statistics, a standard GCN, and Transformer self-attention over modality representations.
