Kunao Zhang, Zhenxing Liang
Tomato is one of the important economic forest fruits in my country. It is the fourth largest vegetable and fruit in my country with an annual output of about 55 million tons, accounting for 7% of the total vegetables. Due to the wide planting area, large yield, and high-quality vegetables are the development direction of modern agriculture. Therefore, this paper adopts the deep learning method, uses the CNN to collect the leaves of tomato diseases and pest detection, uses the stacking to detect the diseases and insect pests on the leaves with the optimized DenseNet121 and MobileNet-V2, and compares the individual DenseNet121 model and MobileNet-V2 model. It shows that the detection results of pests and diseases after fusion are higher than other algorithms, and the final detection accuracy reaches 98.24%, which effectively improves the detection accuracy. It provides a more effective method for the treatment of tomato diseases and insect pests.

iDHS-DPPE: a method based on dual-path parallel ensemble decision for DNase I hypersensitive sites prediction iDHS-DPPE:一种基于双路径并行集成决策的dna酶I超敏感位点预测方法
X. Lv, Yufeng Wang, Hongwen Liu
The DNase I Hypersensitive site (DHS) is the chromatin region that exhibits a hypersensitive response to cleavage by the DNase I enzyme. It is a universal marker for regulatory DNA and associated with genetic variation in a wide range of diseases and phenotypic traits. However, traditional experimental methods have limited the rapid detection of DHS as well as its development. Therefore, effective and accurate methods to explore potential DHSs need to be developed urgently. In this task, a deep learning approach called iDHS-DPPE to predict DHSs in different cell types and developmental stages of the mouse. iDHS-DPPE uses a dual-path parallel integrated neural network to identify DHSs accurately. First, the DNA sequence is segmented into 2-mers to extract information. Then, the DHSs accurately-attention model captures remote dependencies and the MSFRN model enables hierarchical information fusion. The dual models are trained separately to enhance the feature information. Finally, the ensemble decision of two models yields the prediction results, enabling the integration of information from multiple views. The average AUC across all datasets was 93.1% and 93.3% in the 5-fold cross-validation and independent testing experiments, respectively. The experimental results demonstrate that iDHS-DPPE outperforms the state-of-the-art method on all datasets, proving that iDHS-DPPE is effective and reliable for identifying DHSs.
dna酶I超敏位点(DHS)是染色质区域,对dna酶I的裂解表现出超敏反应。它是调控DNA的通用标记,与广泛的疾病和表型性状的遗传变异有关。然而,传统的实验方法限制了DHS的快速检测和发展。因此,迫切需要开发有效、准确的方法来挖掘潜在的dhs。在这项任务中,一种称为iDHS-DPPE的深度学习方法来预测小鼠不同细胞类型和发育阶段的dhs。iDHS-DPPE采用双路径并行集成神经网络精确识别dhs。首先,DNA序列被分割成2-mers来提取信息。然后,dhs精确关注模型捕获远程依赖关系,MSFRN模型实现分层信息融合。对双模型分别进行训练,增强特征信息。最后,通过两个模型的集成决策得到预测结果,实现了多视图信息的集成。在5倍交叉验证和独立测试实验中,所有数据集的平均AUC分别为93.1%和93.3%。实验结果表明,iDHS-DPPE在所有数据集上的性能都优于目前最先进的方法,证明了iDHS-DPPE识别dhs的有效性和可靠性。

Multi-hop question answering for SRLGRN augmented by textual relationship modelling 基于文本关系建模的SRLGRN多跳问答
Xuesong Zhang, G. Li, Dawei Zhang, Zhao Lv, Jianhua Tao
Multi-hop question answering aims to predict answers to questions and generate supporting facts for answers by reasoning over the content of multiple documents. The recently proposed Semantic Role Labeling Graph Reasoning Network (SRLGRN) has achieved excellent performance on multi-hop QA tasks. However, SRLGRN is lacking in modelling the textual relationships, which are import cues for reasoning. To this end, this paper proposes an enhanced SRLGRN multi-hop question answering approach by modelling textual relationships at different granularity (document relationships and sentence relationships). By modelling document relationships, a novel document filter based on document relationship threshold is designed for SRLGRN to dynamically select documents relevant to the question from multiple documents. By modelling sentence relationships, a sentence relationship-aware answer type prediction module is added to SRLGRN, which models sentences in documents as sentence graphs and then uses graph convolution network to predict answer type. The obtained answer type further guide the answer reasoning module of SRLGRN to obtain question answer with supporting facts. The experimental results show that the proposed scheme outperforms SRLGRN in terms of answer prediction and supporting fact prediction, with a 2% improvement in answer F1 metrics and a 3.1% improvement in joint F1 performance.
多跳问答旨在通过对多个文档的内容进行推理,预测问题的答案,并生成支持答案的事实。最近提出的语义角色标注图推理网络(SRLGRN)在多跳QA任务上取得了优异的性能。然而,SRLGRN缺乏对文本关系的建模,而文本关系是推理的重要线索。为此,本文通过对不同粒度的文本关系(文档关系和句子关系)进行建模,提出了一种增强型SRLGRN多跳问答方法。通过对文档关系建模,为SRLGRN设计了一种基于文档关系阈值的新型文档过滤器,从多个文档中动态选择与问题相关的文档。通过对句子关系进行建模,在SRLGRN中增加一个句子关系感知的答案类型预测模块,将文档中的句子建模为句子图,然后利用图卷积网络预测答案类型。获得的答案类型进一步指导SRLGRN的答案推理模块获得具有支持事实的问题答案。实验结果表明,该方案在答案预测和支持事实预测方面优于SRLGRN,答案F1指标提高了2%,联合F1性能提高了3.1%。

Image harmonization with spatial feature interaction and back-projection upsample 基于空间特征交互和上样反投影的图像协调
Tianyanshi Liu, Yuhang Li, Youdong Ding
Without any processing, the synthetic image visually unrealistic due to the established differences in the appearance of the foreground and background. In view of this situation, the task of image harmonization arises at the historic moment, and its purpose is to adjust the foreground appearance of a synthesized image to be closer to the background, thereby eliminating local visual differences. However, due to the limitation of the spatial feature interaction range in the feature extraction process, the global appearance transfer effect is not good. Therefore, to solve this problem, we propose an enhanced spatial feature interaction module. Meanwhile, we propose a back-projection up sampling module, which refines the reconstruction error during the reconstruction up sampling process and better restores the details of the reconstruction foreground. Our experiments on a public dataset, iHarmony4, show that the method effectively generates synthetic images with consistent overall appearance and enhanced detail.
未经任何处理,合成的图像在视觉上不现实,由于既定的前景和背景的外观差异。鉴于这种情况,图像协调的任务应运而生,其目的是调整合成图像的前景外观,使其更接近背景,从而消除局部视觉差异。然而,在特征提取过程中,由于空间特征交互范围的限制,整体外观转移效果不佳。因此,为了解决这一问题,我们提出了一个增强的空间特征交互模块。同时,我们提出了一种反向投影上采样模块,该模块可以细化重建上采样过程中的重建误差,更好地恢复重建前景的细节。我们在公共数据集iHarmony4上的实验表明,该方法有效地生成了具有一致整体外观和增强细节的合成图像。

A framework for automatic identification of neural network structural redundancy based on reinforcement learning 一种基于强化学习的神经网络结构冗余自动识别框架
Tingting Wu, Chunhe Song, Peng Zeng
The increasing structure of neural networks makes it difficult to deploy on edge devices with limited computing resources. Network pruning has become one of the most successful model compression methods in recent years. Existing works usually compress models by removing unimportant filters based on the importance. However, the importance-based algorithms tend to ignore the parameters that extract edge features with small criterion values. And recent studies have shown that the existing criteria rely on norm and lead to similar model compression structures. Aiming at the problems of ignoring edge features and manually specifying the pruning rate in current importance-based model pruning algorithms, this paper proposes an automatic recognition framework for neural network structure redundancy based on reinforcement learning. First, we perform cluster analysis on the filters of each layer, and map the filters into a multi-dimensional space to generate similar sets with different functions. We then propose a criterion for identifying redundant filters within similar sets. Finally, we use reinforcement learning to automatically optimize the cluster dimension, and then determine the optimal pruning rate for each layer to reduce the performance loss caused by pruning. Extensive experiments on various benchmark network architectures and datasets demonstrate the effectiveness of our proposed framework.
神经网络结构的不断增加使得其难以部署在计算资源有限的边缘设备上。网络剪枝是近年来最成功的模型压缩方法之一。现有的作品通常通过根据重要性去除不重要的过滤器来压缩模型。然而,基于重要性的算法往往忽略了提取准则值较小的边缘特征的参数。最近的研究表明,现有的准则依赖于范数,导致模型压缩结构相似。针对目前基于重要度的模型剪枝算法忽略边缘特征和手动指定剪枝率的问题,提出了一种基于强化学习的神经网络结构冗余自动识别框架。首先,我们对每层过滤器进行聚类分析,并将过滤器映射到多维空间中,生成具有不同功能的相似集。然后,我们提出了一个在相似集合中识别冗余滤波器的准则。最后,我们利用强化学习对聚类维度进行自动优化,然后确定每层的最优剪枝率,以减少剪枝带来的性能损失。在各种基准网络架构和数据集上的大量实验证明了我们提出的框架的有效性。

Neighborhood node selection strategy for blockchain networks based on Boltzmann method 基于Boltzmann方法的区块链网络邻域节点选择策略
Chen Zhuo, Wan Guoan, Zhou Chuan
In view of the low block propagation efficiency in the blockchain network, which leads to the low throughput and high acknowledgement delay of the blockchain system, a dynamic node neighbor selection strategy is designed. According to the node elimination rate, neighbor nodes are divided into reserved nodes and replacement nodes. First, all possible combinations of neighbor node replacement are found by using the combination rule. Then, when determining the strategy of each round, the neighbor node with good transmission timeliness is selected as the reserved node to improve the block transmission efficiency. The selection process of reserved nodes is regarded as a multi arm bandit problem, and a mathematical model is established by using Boltzmann selection strategy. The parameters of the strategy, such as node elimination rate and average propagation delay, are analyzed and verified by simulation experiments. The experimental results show that this strategy can optimize the topology of the blockchain network and effectively reduce the average propagation delay of the blockchain network.

Yongsuo Zi, Wang Shu, Yinsheng Hong
The model of agricultural pest killing based on artificial intelligence is constructed. In the AI technology of intelligent agriculture, taking the characteristics of phototactic pests as an example, the expert database of pest killing is constructed by identifying the shape of pests. Build a solar powered solar light trapping platform, and build an intelligent plane rectangular coordinate system on the solar intelligent killing lamp platform. When insects are attracted to the intelligent lighting platform, the platform will automatically compare and identify the insects entering the platform according to the pest database. When they are determined to be pests, start the killing function according to the killing point coordinates provided by the platform, so as to achieve automatic identification and killing of harmful insects, Build an intelligent pest killing model.
构建了基于人工智能的农业害虫杀灭模型。在智能农业的AI技术中,以光致性害虫的特点为例,通过识别害虫的形态,构建害虫灭杀专家数据库。搭建太阳能太阳能捕光平台,在太阳能智能灭灯平台上搭建智能平面直角坐标系。当昆虫被吸引到智能照明平台时,平台会根据害虫数据库自动对进入平台的昆虫进行比对和识别。当确定为害虫时,根据平台提供的杀虫点坐标启动杀虫功能,实现对有害昆虫的自动识别和杀虫,构建智能杀虫模型。
