Development of a mechatronic sorting system for removing contaminants from wool
Automated visual inspection (AVI) systems have been
extended to many fields, such as agriculture and the food, plastic
and textile industries. Generally, most visual systems only inspect
product defects, and then analyze and grade them due to the lack
of any sorting function. This main reason rests with the difficulty of
using the image data in real time. However, it is increasingly important
to either sort good products from bad or grade products into
separate groups usingAVI systems. This article describes the development
of a mechatronic sorting system and its integration with a
vision system for automatically removing contaminants from wool
in real time. The integration is implemented by a personal computer,
which continuously processes live images under the Windows
2000 operating system. The developed real-time sorting approach
is also applicable to many other AVI systems
SageFormer: Series-Aware Graph-Enhanced Transformers for Multivariate Time Series Forecasting
Multivariate time series forecasting plays a critical role in diverse
domains. While recent advancements in deep learning methods, especially
Transformers, have shown promise, there remains a gap in addressing the
significance of inter-series dependencies. This paper introduces SageFormer, a
Series-aware Graph-enhanced Transformer model designed to effectively capture
and model dependencies between series using graph structures. SageFormer
tackles two key challenges: effectively representing diverse temporal patterns
across series and mitigating redundant information among series. Importantly,
the proposed series-aware framework seamlessly integrates with existing
Transformer-based models, augmenting their ability to model inter-series
dependencies. Through extensive experiments on real-world and synthetic
datasets, we showcase the superior performance of SageFormer compared to
previous state-of-the-art approaches
