Title: | An adoption of recurrent neurons to convolutional neural networks | Authors: | Truong Minh Hieu | Keywords: | Recurrent neurons;Convolutional neural networks | Issue Date: | 2022 | Abstract: | Recent COVID-19 pandemic outbreaks lead to the global shortage of RT-PCR test kits. Subsequently, the hospitals and healthcare centers are utilizing lung CT scans to alternate the chemical method. Having an enormous number of cases, deep learning enhanced approaches have been exploited to reduce the repetitive classification task. Several high-quality pieces of research on the convolutional neural network (CNN) backbones were conducted and resulted in significant improvements. This thesis aims to further enhance the state-of-art performance with the adoption of modern recurrent neurons to CNN heads. In the following experiments, the oldfashioned fully-connected layers are replaced by a spare and compact wiring strategy called neural circuit policies with liquid time-constant units encapsulated inside. The architecture was confirmed to have outstanding robustness, stability, dynamics, and interpretability when handling sequential information. However, it does not support non-sequential data. For compatibility, input images have to be reshaped to simulate sequential characteristics. In particular, we investigated sequence modeling on the y-axis, z-axis, and patches. The experiments are organized into three comparison stages to save time and computational resources. Models are selectively upgraded from lightweight to middleweight and then maximum potential concerning hardware capacity. Ultimately, the sequential modeling along the z-axis (Z-NCP) provided the best result. However, it is still a bit behind the traditional fullyconnected networks due to the limitation of hardware power. With the current explosive development of technology, Z-NCP can be revisited soon with more enlarged configurations. |
