Exploration and Research on The Training Path of Accounting Professionals Under The Background of “New Mode And New Value” Digitalization “新模式新价值”数字化背景下会计人才培养路径的探索与研究
Xuebing Zhang
As the digitalization process continues to advance, the scope of application of digital technology continues to expand, especially in the fields of finance and management. In the future, enterprises will inevitably establish financial and financial resource information bases through digital technology, and rely more on mid-to-high-end talents who effectively integrate financial and data analysis. Up to now, the training methods and means of financial accounting students in most colleges and universities follow the convention, which can not make the students' practical operation ability and data analysis ability keep pace with the times, resulting in the mismatch between the students trained by the school and the talents needed by the society. In response to the above problems, this paper discusses the possibility and achievability of adjusting the direction and goals of talent training by optimizing curriculum design and content, and strengthening the transformation of teachers' teaching methods, which will improve the degree of adaptation between students and enterprises, and then provide suggestions for the connection and integration of education and industry.
随着数字化进程的不断推进,数字技术的应用范围不断扩大,特别是在金融和管理领域。未来,企业必然会通过数字技术建立财务和财务资源信息库,并更多地依赖将财务和数据分析有效结合的中高端人才。到目前为止,大多数高校对财务会计专业学生的培养方法和手段都是约定俗成,不能使学生的实际操作能力和数据分析能力跟上时代的步伐,导致学校培养的学生与社会需要的人才不匹配。针对上述问题,本文探讨了通过优化课程设计和内容,加强教师教学方法的转变,调整人才培养方向和目标的可能性和可实现性,从而提高学生与企业的适应程度,进而为教育与产业的对接与融合提供建议。

HED-CNN based Ionospheric Clutter Extraction for HF Range-Doppler Spectrum 基于HED-CNN的高频距离-多普勒频谱电离层杂波提取
Xiangyuan Wang, Wozhan Li, Xiaochuan Wu, Ying Suo, Qiang Yang
High Frequency Surface Wave Radar (HFSWR) suffers seriously with the ionospheric clutter formed from ionosphere echoes. The ionospheric clutter could be extensive and exists all day long, which restricts the detection performance of HFSWR. It is necessary to eliminate the interference of ionospheric clutter which overwhelms target echoes always. However, there is not a prior knowledge about clutter each work cycle, and anti-ionospheric interference technology adapting to all kinds of situations. With the purpose of extracting the ionospheric clutter separately for clutter cancellation, image processing method is adopted to study and analyze the application of deep learning in edge extraction of ionospheric clutter existing in Range-Doppler (RD) spectrum. In this paper, holistically-nested edge detection (HED) based algorithm is adopted and Canny algorithm is used for comparison. It shows that HED algorithm is effective and efficient in edge extraction of ionospheric clutter in RD spectrum.
高频表面波雷达(HFSWR)受到电离层回波形成的电离层杂波的严重影响。电离层杂波可能广泛且全天存在,这制约了HFSWR的探测性能。电离层杂波的干扰总是压倒目标回波,需要对其进行消除。然而,对于杂波的每一个工作周期并没有一个先验的认识,抗电离层干扰技术适应于各种情况。以单独提取电离层杂波进行杂波抵消为目的,采用图像处理方法,研究分析了深度学习在距离多普勒(RD)频谱中存在的电离层杂波边缘提取中的应用。本文采用基于整体嵌套边缘检测(HED)的算法与Canny算法进行比较。实验结果表明,HED算法对RD谱中电离层杂波的边缘提取是有效的。

Qijia Gu, Zhen An, Lanmin Chen, Kunfu Wang
With the increasing application of the Unmanned Aerial Vehicle(UAV) technology, the path planning of UAV is becoming increasing important, However, with the increasing complexity of UAV applications, the application scenario is always complex, crowded with dense obstacles, open, and dynamic. In this paper, we dedicate to deep reinforcement learning algorithms for autonomous obstacle avoidance and navigation of UAV. The navigation problem is considered as a target-driven MDP problem, in which UAV takes its next action conditioned on both its current observation and the destination, Additionally, DRL algorithm with sparse rewards is hard to convergence, we introduce a step-wise dynamic relative goal method to extract the common feature between different navigation targets.
随着无人机技术应用的日益广泛,无人机的路径规划变得越来越重要,然而随着无人机应用的日益复杂,其应用场景总是复杂、拥挤、障碍物密集、开放、动态的。本文研究了用于无人机自主避障和导航的深度强化学习算法。将导航问题视为目标驱动的MDP问题,无人机的下一个行动取决于当前的观测值和目的地,此外,基于稀疏奖励的DRL算法难以收敛,引入了一种逐级动态相对目标方法来提取不同导航目标之间的共同特征。

Research on Chinese Short Text Classification Based on Pre-trained Hybrid Neural Network 基于预训练混合神经网络的中文短文本分类研究
Xuyang Wang, Jie Shi
Traditional text classification models mostly use the Word2vec and Glove to represent word vectors. When these traditional models classify Chinese short text data, they cannot well represent contextual semantic relationships and cannot completely extract text features. In this paper, the ERNIE (Enhanced Representation through Knowledge Integration) model is applied to the hybrid neural network model, which enhances the semantic representation of characters and generates character vectors by associating context semantic relations. Then the CNN (Convolutional Neural Network) and BiLSTM (Bidirectional Long Short Term Memory) are applied to the hybrid neural network to extract the characteristic information of the text data through CNN's different size convolution kernel and BiLSTM's bidirectional network structure. Moreover, in the training process, the weight decay mechanism of the AdamW algorithm is used to replace the traditional Adam algorithm to optimize the model performance. Finally, the obtained classification results are output by softmax classifier. By setting up comparative experiments on the THUCNews dataset and TouTiaoNews dataset, the results show that the Precision, Recall and F1-score of this model have been effectively improved over traditional neural network model and BERT-based model.
传统的文本分类模型大多使用Word2vec和Glove来表示词向量。这些传统模型在对中文短文本数据进行分类时,不能很好地表示上下文语义关系,不能完整地提取文本特征。本文将ERNIE (Enhanced Representation through Knowledge Integration)模型应用到混合神经网络模型中,通过关联上下文语义关系增强字符的语义表示,生成字符向量。然后将CNN(卷积神经网络)和BiLSTM(双向长短期记忆)应用到混合神经网络中,通过CNN不同大小的卷积核和BiLSTM的双向网络结构提取文本数据的特征信息。在训练过程中,利用AdamW算法的权值衰减机制取代传统的Adam算法,优化模型性能。最后,使用softmax分类器输出得到的分类结果。通过在THUCNews数据集和今日头条新闻数据集上进行对比实验,结果表明,该模型的Precision、Recall和F1-score都比传统的神经网络模型和基于bert的模型得到了有效的提高。
