Distributed machine learning technologies (such as data parallelism and model parallelism) have appeared at historic moments and will have extreme large-scale application scenarios. At present, the training speed of distributed machine learning models is slow, and the scale of model parameters is still the main problem in this field. From the perspective of model parallelism, this article aims to design the optimal division method for different models under model parallelism by analyzing the structure of the existing AI application model. According to the framework structure of artificial intelligence application model, design the model optimization partition strategy and model based on parallelism.

Task assignment has always been an important part of the mobile crowd sensing (MCS) system. At present, there are many literatures on task assignment, but there are few researches on cooperative sensing task assignment for heterogeneous intelligent sensing devices. In order to solve the task assignment problem in this multiple heterogeneous sensing device scenario, this paper proposed a task assignment algorithm (TAGA) based on combinatorial double auction and elite-preserving genetic algorithm (EGA). Firstly, the pricing method based on combinatorial double auction is used to determine the offer price and asked price, and then the EGA algorithm is used to determine the final task assignment scheme. The simulation results show that the algorithm can effectively improve the overall utility of the whole system.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129076355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it has been widely adopted for the past decades, research on fairness of recommendation algorithms has been largely neglected until recently. One important paradigm for resolving the issue is regularization. However, researchers have not been able to come up with a consensusly agreed regularization term like regularization framework in other fields such as Lasso or Ridge Regression. In this paper, we borrow concepts from information geometry and propose a new regularization-based fair algorithm called KL-Mat. The algorithmic technique leads to a more robust performance in accuracy performance such as MAE. More importantly, the algorithm produces much fairer results than vanilla matrix factorization approach. KL-Mat is fast, easy-to-implement and explainable.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cylinder via structure and face via structure under the same conditions are analyzed in frequency domain and time domain.

Inspired by Tucker decomposition's success in VQA area, in this paper, we propose VTuckeR, a relatively straightforward but powerful linear model based on Tucker decomposition of the tensor representation of images and object features. In VTuckeR, we control the complexity of the merging scheme while keeping itself good interpretability.

The regularization method usually tends to produce the sparsest solution, however, its solving is an NP-hard problem, and it cannot be directly used in designing the regularized gradient neuro-fuzzy learning method. By exploiting a series of smoothing functions to approximate the regularizer, the proposed BGNFSL0 successfully avoids the NP-hard nature of the original regularization method, while inheriting the advantage in producing the sparsest solution. In this way, BGNFSL0 can prune the network efficiently during the learning procedure and thus improve the generalization capability of the networks. By conducting simulations to compare it with several other popular regularization learning methods, it is found that BGNFSL0 exhibits the best performance in generating the parsimonious network as well as the generalization capability.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123508811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
