Microprocessor-scale transistors detect and respond to biological states and the environment. Your phone may have more than 15 billion tiny transistors packed into its microprocessor chips. The transistors are made of silicon, metals like gold and copper, and insulators that together take an elec
Named entity recognition and relation extraction are essential for structured information construction. However, existing methods, particularly in the field of relation prediction, struggled with information redundancy. In addition, conventional classification models only focus on predicting labels and comparing them to the ground truth, without considering the values and semantics of the labels. In this paper, we propose a novel end-to-end joint entity recognition and relation extraction model named PGLR (Pseudo Graph and Label Reuse for Entity Relation Extraction), which mainly decomposes the task into three hierarchical components to cope with the above issues. Firstly, the model generates a fully connected pseudo-graph that connects all possible entities and relations, followed by a confidence-based module to remove nodes and edges associated with non-relational facts. Secondly, a label reuse approach is employed to aggregate predicted labels and external knowledge, and the represe
grades but most people apply before. particularly people who don t have the resources to take a gap year would be sitting around waiting for the interview. and who asked oxford or cambridge, how is this to happen? i m slightly on the side of universities on this one. they are best kept at arm s length. i think they are doing very good work to get those from more disadvantaged backgrounds to apply. as james points out, there is a limit to what you can do with the education and opportunities are not being created earlier. i think it would end up being, although it looks like a huge commitment, i think it would actually end up being relatively few students who wanted to hang around with those grades who didn t get in the year before, it is a bit of a gating mechanism. one of the more flashy ideas i have seen. flashy ideas i have seen. another sto at flashy ideas i have seen. another story at the flashy ideas i have seen. another story at the front flashy ideas i have seen. another st
