However, reliability issues in memristors, such as\n            <jats:bold>stuck-at faults (SAF)<\/jats:bold>\n            and variations, lead to weight deviation of neural networks and therefore have a severe influence on inference accuracy. In this work, we focus on the reliability issues in memristors for edge devices. We formulate the reliability problem as a 0\u20131 programming problem, based on the analysis of\n            <jats:bold>sum weight variation (SWV)<\/jats:bold>\n            . In order to solve the problem, we simplify the problem with an approximation - different columns have the same weights, based on our observation of the weight distribution. Then we propose an effective mapping method to solve the simplified problem. We evaluate our proposed method with two neural network applications on two datasets. The experimental results on the classification application show that our proposed method can recover 95% accuracy considering SAF defects and can increase by up to 60% accuracy with variation \u03c3 =0.4. The results of the neural rendering application show that our proposed method can prevent render quality reduction.\n          <\/jats:p>","DOI":"10.1145\/3585518","type":"journal-article","created":{"date-parts":[[2023,2,25]],"date-time":"2023-02-25T12:19:20Z","timestamp":1677327560000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A Mapping Method Tolerating SAF and Variation for Memristor Crossbar Array Based Neural Network Inference on Edge Devices"],"prefix":"10.1145","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4360-2098","authenticated-orcid":false,"given":"Yu","family":"Ma","sequence":"first","affiliation":[{"name":"ShanghaiTech University, China and University of Chinese Academy of Sciences, China and Shanghai Engineering Research Center of Energy Efficient and Custom AI IC, Shanghai, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4029-8724","authenticated-orcid":false,"given":"Linfeng","family":"Zheng","sequence":"additional","affiliation":[{"name":"ShanghaiTech University, Shanghai, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9515-9302","authenticated-orcid":false,"given":"Pingqiang","family":"Zhou","sequence":"additional","affiliation":[{"name":"ShanghaiTech University, China and Shanghai Engineering Research Center of Energy Efficient and Custom AI IC, Shanghai, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2023,5,3]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2020.07.053"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202000115"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/DAC18072.2020.9218688"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.23919\/DATE.2017.7926952"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eng.2020.01.007"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/CISDA.2013.6595431"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1145\/2897937.2898010"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2020.01.021"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNNLS.2019.2899262"},{"key":"e_1_3_1_11_2","article-title":"MNIST handwritten digit database","volume":"2","author":"LeCun Yann","year":"2010","unstructured":"Yann LeCun, Corinna Cortes, and C.
