PRISM: Lightweight Multivariate Time-Series Classification through Symmetric Multi-Resolution Convolutional Layers

arXiv — cs.LGWednesday, December 10, 2025 at 5:00:00 AM
  • PRISM has been introduced as a lightweight fully convolutional classifier for multivariate time series classification, utilizing symmetric multi-resolution convolutional layers to efficiently capture both short-term patterns and longer-range dependencies. This model significantly reduces the number of learnable parameters while maintaining performance across various benchmarks, including human activity recognition and sleep state detection.
  • The development of PRISM is significant as it addresses the computational heaviness often associated with Transformer and CNN models, making it a more accessible option for applications in wearable sensing and biomedical monitoring. By halving the number of parameters in its initial layers, PRISM enhances efficiency without sacrificing accuracy.
  • This advancement reflects a broader trend in artificial intelligence towards creating more efficient models that can handle complex tasks with reduced computational resources. The integration of techniques such as graph neural networks and innovative architectures like the Phase-Resonant Intelligent Spectral Model indicates a growing focus on optimizing performance while addressing the limitations of traditional models in various domains.
