The ongoing energy crisis has underscored the urgent need for energy-efficient materials with high utilization efficiency, prompting a surge in research into organic compounds due to their environmental compatibility, cost-effective processing, and versatile modifiability. To address experimental costs time-consuming nature of traditional trial-and-error methods discovery highly functional compounds, we apply 3D transformer-based molecular representation learning algorithm construct...

Watermarking as a novel intellectual property (IP) protection technique can protect field-programmable gate array IPs from infringement. However, existing watermarking techniques may give away sensitive information during the public verification, which enables malicious verifiers or third parties to remove embedded watermark and resell design. Current zero-knowledge verification schemes address leakage issue but are vulnerable embedding attacks, makes them ineffective in preventing...

Automatic Music Transcription (AMT) is usually evaluated using low-level criteria, typically by counting the number of errors, with equal weighting. Yet, some errors (e.g. out-of-key notes) are more salient than others. In this study, we design an online listening test to gather judgements about AMT quality. These take form pairwise comparisons transcriptions same music pairs different systems. We investigate how these correlate benchmark metrics, and find that although they match in many...

Privacy protection problem is one of the most concerning issues related to Location-Based Services (LBS) in our daily life. LBS often requires anonymizing customer's trajectory data. Currently available methods for anonymity assume an entire as anonymous unit, which may lead low efficiency due massive amount data, especially customers travel through a long road. Considering people's routine activities, starting and ending locations trip uncover user's request intent, exposure user privacy....

Research on automatic music transcription has largely focused multi-pitch detection; there is limited discussion how to obtain a machine- or human-readable score transcription. In this paper, we propose method for joint detection and polyphonic piano music. The outputs of our system include both piano-roll representation (a descriptive transcription) symbolic musical notation prescriptive transcription). Unlike traditional methods that further convert MIDI transcriptions into scores, use...

<title>Abstract</title> Vehicle detection algorithms are integral to intelligent traffic management and AI-assisted driving systems. However, the complexity variability of scenarios present significant challenges. Spatial pyramid pooling enhances a model’s ability capture multi-scale contextual information by offering different levels feature representation, which is particularly beneficial in complex scenarios. In this study, we extend spatial Transformer-based models introduce linear...

<title>Abstract</title> Model compression reduces the size of large neural networks while preserving performance. Progressive Blockwise Knowledge Distillation (PBKD) is a model technique that achieves lightweight and efficient student by progressively replacing teacher model's subnet-work block sequence with subnetwork through block-by-block opti-mization process. We propose novel approach to designing blocks emphasizes greater deeper within network in PBKD framework. Compared previous...

Vehicle detection algorithms are essential for intelligent traffic management and autonomous driving systems. Current vehicle largely rely on deep learning techniques, enabling the automatic extraction of image features through convolutional neural networks (CNNs). However, in real scenarios, relying only a single feature unit makes it difficult to fully understand information scenario, thus affecting effect. To address this issue, we propose lightweight algorithm based Mamba_ViT. First,...

Artificial Intelligence (AI) technologies such as deep learning are evolving very quickly bringing many changes to our everyday lives. To explore the future impact and potential of AI in field music sound a doctoral day was held between Queen Mary University London (QMUL, UK) Sciences et Technologies de la Musique du Son (STMS, France). Prompt questions about current trends were generated by academics from QMUL STMS. Students two institutions then debated these questions. This report...

Let $G$ be a connected graph, the principal ratio of is maximum and minimum entries its Perron eigenvector. In 2007, Cioab\v Gregory conjectured that among all graphs on $n$ vertices, kite graph attains ratio. 2018, Tait Tobin confirmed conjecture for sufficientlty large $n$. this article, we show true $n\geq 5000$.
