Detecting hate memes on social media presents a formidable challenge due to their multimodal and often subtle nature. The hateful intent typically emerges from a nuanced interplay between visual and textual elements, which existing methods often fail to capture by inadequately modeling these cross-modal correlations. T...

TS-MTM is proposed, a Temporal-Spectral Masked Time-series Modeling framework that formalizes pretraining within a joint representation space and introduces two synergistic mechanisms: Axial-Period Cross Masking to capture temporal dependencies across phases, and Structure-aware Spectral Magnitude Masking to reconstruc...

Time series forecasting is a cornerstone of numerous real-world applications, where prediction accuracy relies on capturing intricate periodic patterns and evolving spectral dynamics. While Masked Time-series Modeling (MTM) has emerged as a powerful self-supervised paradigm, its conventional one-dimensional (1D) formul...
