This paper presents the uPen, a laser pointer combined with contact-pushed switch, three press buttons and wireless communication module. novel interaction device allows users to interact on large displays at distance or directly surface full-function of mouse. Onboard software enable uPen system identify different provide personalized services them, such as associating corresponding privileges, giving access each participant's private content (e.g., home pages, personal calendars)....

Recommender systems, e.g., movie recommendation, play an important role in our life. However, few recommendation methods have considered the rich visual content information posters and still frames, which can be used to alleviate data sparsity cold start problems recommendation. Moreover, no existing paper has taken feature learning into a unified optimization process. To this end, paper, we focus on how use contents improve performance of propose novel model named matrix factorization...

Graph analytics have been gaining tractions rapidly in the past few years. It has a wide array of application areas industry, ranging from e-commerce, social network and recommendation systems to fraud detection virtually any problem that requires insights into data connections, not just itself. In this paper, we present GeaBase, new distributed graph database provides capability store analyze graph-structured real-time at massive scale. We describe details system implementation, including...

As one of the most widely used recommender systems, movie recommendation plays an important role in our life. However, data sparsity problem severely hinders effectiveness personalized recommendation, which requires more rich content information to be utilized. Posters and still frames, directly display visual contents movies, have significant influences on recommendation. They not only reveal knowledge for understanding movies but also useful user preferences. existing methods rarely...

The relationship between the color of sphalerite and trace elements has aroused interest researchers since a long time, but most study is still in qualitative stage. In this contribution, we made attempt to reveal reflection its element, order discuss genetic significance various colors through quantitative sphalerite. Based on LA-ICP-MS analysis microspectrophotometer samples different types deposits, with significant correlation index were found analyzed by factor analysis. Different...

This paper presents a novel multimodal system to track the participants and identify active speaker in smart meeting room. Indoor localization system, Cicada, is used obtain location identity information of participants. developed by our research group, can provide much higher precision than most visual tracking systems available. Four eight-element microphone arrays are estimate TDOA (Time Difference Arrival) audio signals, which indicators speaker. Integrating these two cues from Cicada...

Abstract Cu:CsPbCl x Br 3‐x quantum dots (QDs) with different Cu‐to‐Pb molar ratios were synthesized via a solvent‐based thermal synthesis method, and highly stable blue‐light PCL@Cu:CsPbCl composite fibers (CFs) prepared by electrohydrodynamic (EHD) technology. The photoluminescence (PL) properties of these Cu 2+ ‐doped QDs the stability polymer encapsulation investigated in this study. results showed that increasing concentration, CsPbCl 1.5 maintained their initial cubic crystal...

We present a new Python toolkit called RecWizard for Conversational Recommender Systems (CRS). offers support development of models and interactive user interface, drawing from the best practices Huggingface ecosystems. CRS with are modular, portable, Large Language Models (LLMs)-friendly, to streamline learning process reduce additional effort research.

Feature weighting can be considered an extension of feature selection. Traditional methods assume that relevance is invariant over the task's domain. As a result, they learn single set weight for entire data set. In this paper, proposed algorithm has been used, which called Simultaneous Clustering and Attribute Discrimination (SCAD) performs clustering simultaneously. First, analyzed in detail, on basis, through series compare experiments, confirms to have high precision; Finally, applied...

This study aims to reveal the application of artificial intelligence, and determine opportunities challenges intelligence in construction industry, proposes design applying technology, which provides a research basis for future smart city development. Additionally, AI applications are pointed this study, insights into key construction-specific challenges.

Though they are a part of traditional Chinese culture, dialects have gradually become diluted and marginalized under modernization globalization. To promote the inheritance development dialects, we developed smart dialect-featured short video platform. This platform integrated dialect elements to highlight dialects. It allows for multi-dimensional multi-level expansion inheritance, breaking limitations methods. We analyzed current status dilution role platforms cultural dissemination. The...

In order to construct the national sports information network following steps of developed countries, several factors which influence china government affairs were discussed. Investigation China's eastern region and western region, in construction subjective objective factors, pointed out these regions achievements shortcomings. Reasons given based on differences between economic, technical personnel causes formation. end, this paper proposed some improved guidance advices was very useful...

Echo Wall is an interactive artwork, which enables people to communicate with the environment and other in everyday setting. The installation set up on a regular wall public where everyone could participate interaction. When one speaks or makes noise front of wall, projected animation will change according location voice features person. People can each by generating different animations. microphone array technology used provides opportunity experience interaction more naturally without any...

In this paper, an experimental method has been proposed to determine the Discrete Cosine Transformation how work on JPEG image compression and compare computational complexity different forms of DCT, which include common 2D-DCT, fast 2D-DCT (FFDCT DFDCT) matrix DCT method.
