Student Award 2025

Professor Derrick Jiang (Assistant Professor of EE) and his research team have been honored with the Y-LOT’s 3rd Hong Kong SciTech Pioneers Award 2023-2024, in recognition of their outstanding dedication and contributions to emerging technologies for electric vehicles.

The award, hosted by Y-LOT Foundation and sponsored by Herson Land and Innovation and Technology Commission (ITC), aims to recognize and celebrate the valuable contributions of outstanding scientists and research teams in the fields of Deep Tech, Biotechnology, Space Science, ESG, and Future Innovation. Prof Jiang is the awardee in the Deep Tech category.

Prof Arindam Basu (Professor of EE) and his PhD students, namely Mr Pao Sheng Sun and Miss Biyan Zhou, have published a paper in the top journal – Nature Communications, on 11 February 2025. The paper titled “The neuro bench framework for Benchmarking Neuromorphic Computing Algorithms and Systems” is a collaborative work with scholars coming from a worldwide consortium on brain-inspired or neuromorphic computing spanning 57 institutes. Authors are grouped based on contributions. The team primarily developed the main algorithm track results on the non-human primate motor prediction task, one out of only four benchmark tasks chosen from around the world.

To give you a glimpse of the research work, here is a quote from the abstract: This article presents NeuroBench, a benchmark framework for neuromorphic algorithms and systems, which is collaboratively designed from an open community of researchers across industry and academia. NeuroBench introduces a common set of tools and systematic methodology for inclusive benchmark measurement, delivering an objective reference framework for quantifying neuromorphic approaches in both hardware-independent and hardware-dependent settings.

In this work, we experimentally demonstrate the implementation of a non-linear activation function integrated with a ramp analog-to-digital conversion (ADC) at the periphery of the memory to improve in-memory implementation of RNNs. Our approach uses an extra column of memristors to produce an appropriately pre-distorted ramp voltage such that the comparator output directly approximates the desired nonlinear function. We experimentally demonstrate programming different nonlinear functions using a memristive array and simulate its incorporation in RNNs to solve keyword spotting and language modelling tasks. Compared to other approaches, we demonstrate manifold increase in area-efficiency, energy-efficiency and throughput due to the in-memory, programmable ramp generator that removes digital processing overhead.
