CF-JEPA: Mask-free forward prediction with asymmetric encoder utilization for time-series representation learning
arXiv:2606.07031v1 Announce Type: new Abstract: Self-supervised learning (SSL) for time-series representation learning is dominated by two paradigms: contrastive methods, which face challenges in constructing positive or negative pairs, and masking-based methods, which disrupt the temporal continuity of time-series signals. Joint-Embedding Predictive Architecture (JEPA) offers a promising alternative by predicting in representation space rather than reconstructing raw inputs. However, existing time-series JEPA variants still rely on masking and therefore inherit its continuity problem. Crop-ba
The proliferation of time-series data from IoT, sensors, and other sources necessitates more efficient and robust representation learning techniques to process and make sense of this information.
This development proposes a novel approach to self-supervised learning for time-series data, potentially overcoming the limitations of current masking and contrastive methods, which could lead to more robust and accurate AI models in various applications.
The reliance on masking and the challenges of constructing positive/negative pairs in time-series self-supervised learning are directly addressed by a mask-free forward prediction method, potentially accelerating AI development for dynamic data.
