Deploying pre-trained transformer models like BERT on downstream tasks in resource-constrained scenarios is challenging due to their high inference cost, which grows rapidly with input sequence length. In this work, we propose a constraint-aware and ranking-distilled token pruning method ToP, selectively removes unnecessary tokens as passes through layers, allowing the model improve online speed while preserving accuracy. ToP overcomes limitation of inaccurate importance ranking conventional...
A 6.6kW 500kHz bidirectional isolated DC/DC converter based on GaN and SiC wide band gap (WBG) semiconductor devices is developed for 800V electric vehicle (EV) on-board charging, which simpler more reliable than the method of output using multilevel topology. Firstly, working characteristics resonant DAB topology phase-shift control are analyzed. Compared with delay-time strategy, it has factures narrow switching frequency range small turn-off current, very suitable high applications...
The coast–ship bistatic high-frequency surface wave radar (HFSWR) not only has the anti-interference advantages of coast-based HFSWR, but also maneuverability and an extended detection area shipborne HFSWR. In this paper, theoretical formulas were derived for radar, including first-order sea clutter scattering cross-section Doppler frequency shift moving targets. Then, simulation results spectrum under different operating conditions given, range broadening its influence on target...
In this paper, we present CoMRI, compressed multiresolution index, our system for fast sequence similarity search in DNA databases. We employ virtual bounding rectangle (VBR) concept to build a compressed, grid style index structure. An advantage of format over trees is subsequence location information given by the order corresponding VBR list. Taking VBRs, structure fits into reasonable size memory easily. Together with new optimized algorithm, query speed improved significantly. Extensive...
Vision-Language Pretraining (VLP) has significantly improved the performance of various vision-language tasks with matching images and texts. In this paper, we propose VL-Match, a framework Enhanced Token-level Instance-level Matching. At token level, Replaced Token Detection task is designed to boost substantial interaction between text tokens images, where encoder VLP works as generator generate corrupted text, multimodal discriminator predict whether each in matches image. instance...

Multi-index vector search has become the cornerstone for many applications, such as recommendation systems. Efficient in a multi-modal hybrid space is challenging since no single index design performs well all kinds of data. Existing approaches to processing multi-index queries either suffer from algorithmic limitations or inefficiency. In this paper, we propose OneSparse, unified multi-vector query system that incorporates multiple posting-based indices, which enables highly efficient...
Query generation is a critical task for web search engines (e.g. Google, Bing) and recommendation systems. Recently, state-of-the-art query methods leverage Large Language Models (LLMs) their strong capabilities in context understanding text generation. However, they still face challenges generating high-quality queries terms of inferring user intent based on interaction history. In this paper, we propose Token-level Proximal Policy Optimization (TPPO), noval approach designed to empower...
