BiHDTrans: binary hyperdimensional transformer for efficient multivariate time series classification
Read the original on arXiv Machine Learning →BiHDTrans is a neurosymbolic binary hyperdimensional transformer that merges self‑attention with hyperdimensional computing to classify multivariate time series efficiently. It surpasses existing HD models by at least 14.47% and binary transformers by 6.67% on average, while an FPGA‑accelerated implementation reduces inference latency 39.4× compared to state‑of‑the‑art binary transformers. Even with a 64% reduction in hyperspace dimensionality, BiHDTrans remains competitive, achieving 1–2% higher accuracy with 4.4× smaller model size and nearly 50% lower latency than the full‑dimensional baseline.
