    Improving machine translation and post-editing for Chinese tourism texts using transformer-based models

    As the digital age and globalization continue to evolve, the demand for accurate machine translation of tourism texts has increased substantially. This paper investigates how to improve the quality of machine translation (MT) and machine translation post-editing (MTPE) of Chinese tourism texts for non-native speakers. A review of the machine translation literature reveals a significant progression in translation methods from rule-based to corpus-based, statistical, and finally to the current neural machine translation (NMT) models. Despite its advanced capabilities, NMT requires large amounts of parallel data for training, which often presents challenges. This study proposes the use of Transformer-based models for MT and MTPE to improve translation quality. A dataset was curated from online sources, mainly Chinese tourism websites. The methodology involved pre-processing the data, performing machine translation using the Transformer model, and post-editing the results. The experiment demonstrated an increase in the BLEU score, suggesting an improvement in translation quality. However, challenges such as the handling of synonyms and geographical nouns were encountered, indicating the need for further research and model optimization.

    Comparative study of the execution efficiency of Python and C++——Based on topological sorting

    C++, a compiled language, and Python, an interpreted language, are among those essential coding languages that function in diverse areas of the current computer industry. However, different languages have disparate benefits and fit in various circumstances. When large amounts of data are involved or fast execution speed is required, one should consider which language performs better. This research mainly aims to find out whether C++ or Python is more efficient through Topological Sorting, which is utilized to linearize the vertices of a Directed Acyclic Graph (DAG). In the approach of coding the Topological Sorting algorithm in C++ and Python and comparing their execution times on each matrix representing a DAG randomly generated by a Python program, it is concluded that C++ generally has a higher efficiency than Python.

    A literature review on snow simulation with MPM in computer graphics

    Snow simulation is always a challenge in the computer graphics community due to its combined nature of solids and fluids. In the past, researchers usually applied different solvers to computationally simulate the behavior of snow at different phases, which made the simulation both slow and complicated. In 2013, the material point method, abbreviated as MPM, was first introduced for snow simulation, eliminating the need for multiple solvers. This paper investigates the history of the application of MPM to snow simulation in computer graphics specifically, and offers an overview of its evolution since the pioneering work by Stomakhin. It aims at showing the current state-of-art as well as any limitations. Nowadays, the development of MPM and snow simulation focuses on improvements of the stability and physical accuracy of the method itself, and the generalization of the application scope from snow to arbitrary granular materials. The trade-off between efficiency and accuracy remains a problem, thus it introduces more potential research directions, ranging from developing simpler mathematical models for better physical accuracy to incorporating machine learning techniques to accelerate the simulation process.

    FPGA accelerator for wireless AR/VR display

    Nowadays, Virtual reality(VR) and Aug- mented reality(AR) have become one of the most popular format in many fields, for example video gaming, medical training and even aviation. VR and AR technique simulates images in an edge device, it gives an immersive experience to the users. AR/VR requires high resolution and high FPS for good experience. However, most of the AR/VR devices are made of embedded device due to the limitation of the size and weight of the headset. It is hard to render high quality frames in headset. Many popular VR/AR applications utilize the desktop and server to render the frames and transmit the frames to VR/AR for display. Data transmission from a more powerful device to the VR/AR device requires high transmission speed (1.6GB/s for Oculus quest 2), it is hard to provide the bandwidth with wireless protocol (WIFI/5G). HDMI or DP cable can be applied, but they limit the use case of the VR/AR devices. In this paper, we proposed a latency sensitive super sampling hardware accelerator for VR/AR devices based on machine learning which can significantly reduce the bandwidth requires to transmit frames to VR/AR. In our experiment, the super sampling can deliver high-resolution frames with 25% bandwidth which enable the wireless protocal for VR/AR devices. We implemented the accelerators in RTL and synthesis it with 130 nm skywater pkd. The power consumption of our accelerator at normal data rate for VR/AR devices is 20.97 w and the area is 299.602 mm2.

    Adaptive simulation of digital signal transmission

    High-order modulated signals have lower anti-interference ability than low-order modulated signals with the same modulation method and conditions. In situations with low signal-to-noise ratios, the quality of high-order signals can degrade significantly. An algorithm capable of intelligently switching the modulation order based on the current signal-to-noise ratio can effectively address this issue. This paper presents an adaptive signal transmission algorithm that intelligently selects different orders of Phase shift keying (PSK) modulation depending on varying signal noise ratio (SNR) conditions, while ensuring the user-specified upper limit of bit error rate (BER). This approach guarantees signal transmission quality. The algorithm is implemented in Python and involves simulating the relationship curve between SNR and BER for different PSK orders. This simulation is combined with theoretical transmission rate analysis, resulting in an adaptive algorithm that intelligently switches modulation methods under complex conditions to meet transmission requirements. The proposed algorithm dynamically adapts to diverse user requirements for signal-to-noise ratios in various environments. It achieves this by adjusting the modulation order, calculating theoretical transmission times based on the given signal frequency, and ultimately verifying the actual bit error rate through transmission and testing. Upon testing, this design successfully achieved its intended goals.
