eMargin: Revisiting Contrastive Learning with Margin-Based Separation
Abdul-Kazeem Shamba, Kerstin Bach, Gavin Taylor
We revisit previous contrastive learning frameworks to investigate the effect of introducing an adaptive margin into the contrastive loss function for time series representation le…
