Decision trees, random vector functional link neural network and their ensembles
Published 2020“…However, randomization based neural networks such as Random Vector Functional Link (RVFL) neural network eschew these issues by randomly fixing some parts (parameters) of the network while optimizing the rest using a closed form solution or an iterative procedure. Ensemble of classifiers, also known as multiple classifier system, is a widely researched and frequently applied approach in machine learning. …”

The deep learning techniques applied to electromagnetic imaging via ground-penetrating radar
Published 2023“…In GPR inverse problem, the recorded GPR data is used to reconstruct subsurface permittivity maps, of great significance for mapping the subsurface utilities as well as detecting, recognizing, and monitoring the subsurface objects and living entities (such as tree roots). Traditional iterative algorithms developed for reconstructing permittivity maps from GPR data suffer from high computational costs and low accuracy when applied to complex scenarios. …”

Design of low-power gesture recognition system and self-organizing map processors
Published 2024“…In chapter 4, to improve the recognition accuracy under the complex background and reduce the processing latency of the system, we proposed a low-power HGR system with the following algorithmic improvements, including 1) color- and depth-based hand segmentation method, 2) bi-directional convolution-based feature extraction, and 3) iteration-free feature clustering algorithm. Additionally, to implement the aforementioned HGR algorithms with high power efficiency, the hardware architecture adopts the following optimizations, including 1) continuous low-power control of the computing-intensive modules, 2) fully-pipelined architecture for feature extraction and data clustering, and 3) computing-efficient cluster combiner without redundant comparison. …”
