Normally, it needs 3 pass of input memory access to compute attention, and the on-chip storage requirement is coupled with the input length, both of which pose significant memory issues. Further, the computation burden is heavy for long inputs. This paper proposes an algorithm-hardware co-design for attention. On algorithm side, it uses a linear-softmax fused kernel to fuse the matrix multiplication and non-linear functions, which enables high on-chip memory source utilization. On hardware side, it shows an accelerator named BLADE with identical partial product removing, which eliminates unnecessary computation by exploiting math feature of softmax.

NLMs are usually used in the second-pass lattice rescoring rather than the first-pass decoding, since its encoded infinite history virtually cannot be compiled into static decoding graphs. However, the modeling power of NLMs is not fully leveraged due to the constraints imposed by the lattice, leading to accuracy loss. To improve this, on-the-fly composition decoders were proposed to utilize NLMs in first-pass decoding with increased computational cost. In this paper, an asynchronous lazy-evaluation token-group decoder with exact lattice generation is proposed to reduce the computational cost of the on-the-fly composition decoder, achieving significant decoding speedup. More specifically, having a novel token-group with a representative element data structure, the proposed decoder performs lazy-evaluation which expands the tokens until a word boundary is reached. Furthermore, based on the score of the representative element in a token-group, the decoder prunes unpromising tokens by an A* algorithm. The experiments show that the proposed decoder can accelerate the vanilla on-the-fly composition decoder by up to 6.9 times, and get paths with even better average likelihoods than lattice rescoring approaches.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas stronger individual diversities inevitably result in decreasing accuracies of partial individuals, it brings a great challenge for improving the ensemble performance. In fact, we observe that the contribution of individuals should be a crucial factor for ensemble learning, which can effectively alleviate the problem of balancing diversity and accuracy, but it is ignored in most existing studies. Based on this, we propose a new incremental non-linearity deep ensemble learning method that effectively combines multiple individuals based on the exploration of individual contributions by utilizing deep learning. In the proposed method, a characterization matrix is first constructed to represent the original individuals. Then, a deep ensemble network is constructed to explore the potential contribution of individuals in conjunction with the optimization objective of ensemble learning. Interestingly, a special layer is designed to achieve the minimization of ensemble error. Finally, experimental results on public datasets illustrate that the proposed method achieves the average 0.66–4.8% performance improvements compared to existing typical ensemble methods.","PeriodicalId":11556,"journal":{"name":"Electronics Letters","volume":"61 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ell2.70178","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
