SemiHD: Semi-Supervised Learning Using Hyperdimensional Computing


AdaptHD: Adaptive Efficient Training for Brain-Inspired Hyperdimensional Computing

  • Conference: BioCAS 2019 - IEEE Biomedical Circuits and Systems
  • Work at University of California, San Diego and EPFL, Lausanne
  • Group of prof. Tajana S. Rosing and Giovanni De Micheli
  • AdaptHD introduces the definition of learning rate in HD computing and proposes two approaches for adaptive training: iteration-dependent and data-dependent. In the iteration-dependent approach, AdaptHD uses a large learning rate to speedup the training procedure in the first iterations, and then adaptively reduces the learning rate depending on the slope of the error rate.

QuantHD: A Quantization Framework for FPGA Acceleration of Hyperdimensional Computing

  • Work at University of California, San Diego
  • Group of prof. Tajana S. Rosing
  • We invented a new machine learning algorithm which can achieve on average 34.1x and 4.1x energy efficiency improvement on training and testing respectively, and 8.2x and 13.4x faster computing in training and testing. This is compared to the previous state-of-the-art HD computing ML algorithms. It provides similar classification accuracy as low-cost state-of-the-art Machine Learning algorithms, while significantly improving the energy efficiency. 


Bit-Serial HD: Approximate Hyperdimensional Computing in Machine Learning

  • Work at University of California, San Diego and EPFL
  • Groups of Prof. Tajana S. Rosing (UCSD) and Prof. Giovanni De Micheli (EPFL)
  • We invented a new HD computing acceleration framework, which significantly reduces the power consumption of Machine Learning algorithms, while maintaining almost the same classification accuracy 


LookHD: Acceleration of Hyperdimensional Computing Exploiting Computation Reuse

  • Work at University of California, San Diego
  • Group of prof. Tajana S. Rosing
  • We invented LookHD: a method which compresses a HD algorithm matrix into a single vector without significantly decreasing classification accuracy. This method is 2.2x faster and 4.1x more energy efficient, as compared to existing HD computing algorithms
