ASR - VLSP 2021: Automatic Speech Recognition with Blank Label Re-weighting
VNU Journal of Science: Computer Science and Communication Engineering - Tập 38 Số 1 - 2022
End-to-end models have significant potential in most languages and recently proved the robustness in ASR tasks. Many robust architectures are proposed, and among many techniques, Recurrent Neural Network - Transducer (RNN-T) shows remarkable success. However, with background noise or reverb in spontaneous speech, this architecture generally suffers from high deletion error problems. For this reaso......
Combining Power Allocation and Superposition Coding for an Underlay Two-way Decode-and-forward Scheme
VNU Journal of Science: Computer Science and Communication Engineering - Tập 37 Số 1 - 2021
In this paper, we analyze an underlay two-way decode-and-forward scheme in which secondary relays use successive interference cancellation (SIC) technology to decode data of two secondary sources sequentially, and then generate a coded signal by superposition coding (SC) technology, denoted as SIC-SC protocol. The SIC-SC protocol is designed to operate in two time slots under effects from an inter......
A Big Data Analytics Framework for IoT Applications in the Cloud
VNU Journal of Science: Computer Science and Communication Engineering - Tập 31 Số 2 - 2015
The Internet of Things (IoT) is an evolution of connected networks including million chatty embedded devices. A huge amount of data generated day by day by things must be aggregated and analyzed with technologies of the "Big Data Analytics". It requires coordination of complex components deployed both on premises and Cloud platforms. This article proposes BDAaaS, a flexibly adaptive cloud-based fr......
ViMRC - VLSP 2021: Context-Aware Answer Extraction in Vietnamese Question Answering
VNU Journal of Science: Computer Science and Communication Engineering - Tập 38 Số 2 - 2022
MRC is challenging the natural language processing fields; machines automatically have to answer questions based on specific passages for this task. In recent years, machine reading comprehension (MRC) has received much attention; many articles have been written about this task. However, most of those articles only develop models in two main languages, English and Chinese. In this article, we prop......
Coreference Resolution in Vietnamese Electronic Medical Records
VNU Journal of Science: Computer Science and Communication Engineering - Tập 34 Số 2 - 2018
Electronic medical records (EMR) have emerged as an important source of data for research in medicine andinformation technology, as they contain much of valuable human medical knowledge in healthcare and patienttreatment. This paper tackles the problem of coreference resolution in Vietnamese EMRs. Unlike in English ones,in Vietnamese clinical texts, verbs are often used to describe disease symptom......
Improved Particle Swarm Optimization of Three-Dimensional Path Planning for Fixed Wing Unmanned Aerial Vehicle
VNU Journal of Science: Computer Science and Communication Engineering - Tập 35 Số 2 - 2019
Path planning for Unmanned Aerial Vehicle (UAV) targets at generating an optimal global path to the target, avoiding collisions and optimizing the given cost function under constraints. In this paper, the path planning problem for UAV in pre-known 3D environment is presented. Particle Swarm Optimization (PSO) was proved the efficiency for various problems. PSO has high convergence speed yet with i......
SV - VLSP2021: The Smartcall - ITS’s Systems
VNU Journal of Science: Computer Science and Communication Engineering - Tập 38 Số 1 - 2022
This paper presents the Smartcall - ITS’s systems submitted to the Vietnamese Language and Speech Processing, Speaker Verification (SV) task. The challenge consists of two tasks focusing on the development of SV models with limited data and testing the robustness of SV systems. In both tasks, we used various pre-trained speaker embedding models with different architectures: TDNN, Resnet34. After a......
A Framework for Modeling and Modular Verifying of Component-based System Designs
VNU Journal of Science: Computer Science and Communication Engineering - Tập 32 Số 2 - 2016
This paper introduces a framework for modeling and verifying safety properties of component-based systems (CBS) by extracting their models from designs in form of UML 2.0 sequence diagrams. Given UML 2.0 sequence diagrams of CBS, the framework extracts regular expressions exactly describing behaviors of the system. From these expressions, the proposed framework then generates accurate models repre......
Combined Power Ratio Calculation, Hadamard Transform and Least Mean Squares Algorithm for Channel Mismatch Calibration in Time-Interleaved ADCs
VNU Journal of Science: Computer Science and Communication Engineering - Tập 36 Số 2 - 2020
This paper presents a method for all-digital background calibration of multiple channel mismatches including offset, gain and timing mismatches in time-interleaved analog-to-digital converters (TIADCs). The average technique is used to remove offset mismatch at each channel. The gain mismatch is calibrated by calculating the power ratio of the sub-ADC over the reference ADC. The timing skew mismat......
A General Computational Framework for Prediction of Disease-associated Non-coding RNAs
VNU Journal of Science: Computer Science and Communication Engineering - Tập 35 Số 2 - 2019
Since last decade, we have been witnessing the raise of non-coding RNAs (ncRNAs) in biomedical research. Many ncRNAs have been identified and classified into different classes based on their length in number of base pairs (bp). In parallel, our understanding about functions of ncRNAs is gradually increased. However, only small set among tens of thousands of ncRNAs have been well studied about thei......
