Sobol Sequence Optimization for Hardware-Efficient Vector Symbolic Architectures

no code implementations17 Nov 2023 Sercan Aygun, M. Hassan Najafi

The performance of the proposed technique is evaluated in comparison to two traditional approaches of generating hypervectors based on linear-feedback shift registers and MATLAB random function.

uHD: Unary Processing for Lightweight and Dynamic Hyperdimensional Computing

no code implementations16 Nov 2023 Sercan Aygun, Mehran Shoushtari Moghadam, M. Hassan Najafi

To construct HDC models for vision applications, the current state-of-the-art practice utilizes two parameters for data encoding: pixel intensity and pixel position.

Learning from Hypervectors: A Survey on Hypervector Encoding

no code implementations1 Aug 2023 Sercan Aygun, Mehran Shoushtari Moghadam, M. Hassan Najafi, Mohsen Imani

It zeroes in on the HDC system input and the generation of hypervectors, directly influencing the hypervector encoding process.

TaxoNN: A Light-Weight Accelerator for Deep Neural Network Training

no code implementations11 Oct 2020 Reza Hojabr, Kamyar Givaki, Kossar Pourahmadi, Parsa Nooralinejad, Ahmad Khonsari, Dara Rahmati, M. Hassan Najafi

In this work, first we present a novel approach to add the training ability to a baseline DNN accelerator (inference only) by splitting the SGD algorithm into simple computational elements.
