Abstract Identifying the change‐prone parts of software could help managers and developers to effectively allocate maintenance resource time during early phases life cycle. Change‐proneness prediction on file level with binary classification methods makes such identification possible. As fact that files frequently account for a small part all files, performance standard is not satisfying. In this paper, we employ imbalanced learning methods, including bagging, resampling, especially their...

The pervasiveness of personalized collaborative recommender systems has shown the powerful capability in a wide range E-commerce services such as Amazon, TripAdvisor, Yelp, etc. However, fundamental vulnerabilities leave space for malicious users to affect recommendation results attackers desire. A vast majority existing detection methods assume certain properties attacks are given advance. In reality, improving performance is usually constrained due challenging issues: (a) various types...

So technique correct, feasible, proved by great deal simulating tests.

Internet of things is characterized by limited energy and distributed topology. In this scenario, a secure energy-saving routing algorithm plays significant role in ensuring the performance things. Due to different standards communication stacks, traditional security mechanisms heavily rely on trust management function well. article, we propose an energy-aware trustworthy multi-hop model for To balance consumption trust, whole from source destination should be considered appraisal, rather...

In a high-speed rail system, the driver repeatedly adjusts train’s speed and traction while driving, causing high level of energy consumption. This also leads to instability operation, affecting passengers’ experiences operational efficiency system. To solve this problem, we propose variational graph auto-encoder (VGAE) model using neural network learn posterior distribution. can effectively capture correlation between components system simulate drivers’ operating state accurately. The...

Diffusion models, such as Stable Diffusion, have made significant strides in visual generation, yet their paradigm remains fundamentally different from autoregressive language complicating the development of unified language-vision models. Recent efforts like LlamaGen attempted image generation using discrete VQVAE tokens, but large number tokens involved renders this approach inefficient and slow. In work, we present Meissonic, which elevates non-autoregressive masked modeling (MIM)...
