However, the scarcity of labeled data remains a prominent challenge in CSI-based HAR, primarily due to privacy concerns and the incomprehensibility of CSI data. Concurrently, Self-Supervised Learning (SSL) has emerged as a promising approach for addressing the dilemma of insufficient labeled data. In this article, we undertake a comprehensive inventory and analysis of different categories of SSL algorithms, encompassing both previously studied and unexplored approaches within the field. We provide an in-depth investigation and evaluation of SSL algorithms in the context of WiFi CSI-based HAR, utilizing publicly available datasets that encompass various tasks and environmental settings. To ensure relevance to real-world applications, we design experiment settings aligned with specific requirements. Furthermore, our experimental findings uncover several limitations and blind spots in existing work, shedding light on the barriers that need to be addressed before SSL can be effectively deployed in real-world WiFi-based HAR applications. Our results also serve as practical guidelines and provide valuable insights for future research endeavors in this field.<\/jats:p>","DOI":"10.1145\/3715130","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T11:53:41Z","timestamp":1737978821000},"page":"1-38","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Evaluating Self-Supervised Learning for WiFi CSI-Based Human Activity Recognition"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7272-6965","authenticated-orcid":false,"given":"Ke","family":"Xu","sequence":"first","affiliation":[{"name":"Centre for Intelligent Healthcare, Coventry University, Coventry, United Kingdom of Great Britain and Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8704-502X","authenticated-orcid":false,"given":"Jiangtao","family":"Wang","sequence":"additional","affiliation":[{"name":"Coventry University, Coventry, United Kingdom of Great Britain and Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5177-8320","authenticated-orcid":false,"given":"Hongyuan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Institute of Infocomm Research, Agency for Science Technology and Research, Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8077-4548","authenticated-orcid":false,"given":"Dingchang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Coventry University, Coventry, United Kingdom of Great Britain and Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2025,3,23]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.engappai.2019.103281"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/3460120.3484777"},{"key":"e_1_3_1_4_2","doi-asserted-by":"crossref","first-page":"552","DOI":"10.1109\/GCWkshps56602.2022.10008537","volume-title":"Proceedings of the 2022 IEEE Globecom Workshops (GC Workshops \u201922)","author":"Bocus Mohammud J.","year":"2022","unstructured":"Mohammud J.
