@inproceedings { , title = {Human activity recognition with deep metric learners.}, abstract = {Establishing a strong foundation for similarity-based return is a top priority in Case-Based Reasoning (CBR) systems. Deep Metric Learners (DMLs) are a group of neural network architectures which learn to optimise case representations for similarity-based return by training upon multiple cases simultaneously to incorporate relationship knowledge. This is particularly important in the Human Activity Recognition (HAR) domain, where understanding similarity between cases supports aspects such as personalisation and open-ended HAR. In this paper, we perform a short review of three DMLs and compare their performance across three HAR datasets. Our findings support research which indicates DMLs are valuable to improve similarity-based return and indicate that considering more cases simultaneously offers better performance.}, conference = {27th International conference on case-based reasoning workshop (ICCBR-WS19), co-located with the 27th International conference on case-based reasoning (ICCBR19)}, note = {INFO COMPLETE (Now published, checked and updated 16/3/2020 LM) PERMISSION GRANTED (version = VoR; embargo = none; licence = BY; SHERPA = http://sherpa.ac.uk/romeo/issn/1613-0073/ ) DOCUMENT RECEIVED (AAM rec'd from contact 13/8/2019 LM)}, pages = {8-17}, publicationstatus = {Published}, publisher = {CEUR Workshop Proceedings}, url = {https://rgu-repository.worktribe.com/output/350316}, keyword = {Artificial Intelligence & Reasoning (AIR), Living in a Digital World, Human activity recognition, Deep metric learning, Deep learning, Metric learning, Matching networks}, year = {2020}, author = {Martin, Kyle and Wijekoon, Anjana and Wiratunga, Nirmalie} editor = {Kapetanakis, Stelios and Borck, Hayley} }
