In this paper, we propose a stacked model with autoencoder for financial time series prediction. A stacked autoencoder model is used for feature extraction of high-dimensional stock factors. The factors after dimensionality reduction serve as input to the stacked model to predict the next-day returns of the stocks. In this paper, the stacked autoencoder not only has the effect of reducing the dimension, but also eliminates the redundant information in the data to a certain extent, which can effectively improve the predictive capacity of the model. The constituent stocks of CSI300 are used as backtest samples, and the experiment shows that the stacked model with autoencoder can obtain more than 50% of excess return in 2019.

The joint extraction of entity and relation is an important task in information extraction. Previously, most models in entity relationship extraction assumed that the relationship was discrete. Unfortunately, this assumption is often violated. In order to solve the problem of overlapping in the entity relationship, considering the relationship between extraction under the premise of have the features of multiple targets, this paper puts forward a multi-objective depend on the relationship between extraction model, which transforms the relationship extraction task into a sequence-tagged task. The model uses Iterated Dilated Convolutional Neural Network (IDCNN) and BiLSTM to encode the words in order to more fully extract the semantics in the text. First, determine the target entity subject (s), and then predict all corresponding object (o) and relationship (r) according to s. Experiments show that our model is significantly better than the baseline methods.
实体和关系的联合抽取是信息抽取中的一个重要任务。以前,大多数实体关系抽取模型都假定实体关系是离散的。不幸的是,这个假设经常被违背。为了解决实体关系中的重叠问题,在考虑关系抽取具有多目标特征的前提下,本文提出了一种多目标依赖关系抽取模型,将关系抽取任务转化为序列标记任务。该模型使用迭代扩展卷积神经网络(IDCNN)和BiLSTM对单词进行编码,以便更充分地提取文本中的语义。首先确定目标实体主体(s),然后根据s预测所有对应的对象(o)和关系(r)。实验表明,我们的模型明显优于基线方法。

With the popularization of the internet and the increase of video facilities, the recognition and segmentation of actions in the video have become research highlights of high application value. Different from images, the information in the video is more complex and also brings time sequences as a new dimension. This paper proposes a video action recognition and segmentation model in the human keypoint detection task. The main contributions are as follows:1) Based on the speech signal processing method, this paper designs an analysis framework for video action, which consists of three steps. The first step is to obtain data from the key point frame of the human body; the second is the action segmentation model; the third is to visualize the model results;2)the dynamic time warping algorithm is used and improved from calculation cost and constraint conditions;3) a distance function is designed to measure the similarity between time series. Four kinds of features are introduced, and the final distance is the weighted sum of the four kinds of features;4) a non-maximum suppression method is designed to filter the overlapped segments to get the final results. Experiment design verifies the validity of the proposed model and the importance of proposed features is illustrated.

In terms of engineering vehicle faults, CAN communication faults account for a large proportion. In order to detect the CAN communication faults of electronic control units (ECUs) for diesel vehicles, this paper designs a CAN communication detection system for engineering vehicle ECUs, and a fault detection algorithm is proposed for diesel vehicle ECU based on CAN. This system can analyze and diagnose the physical link faults of CAN based on "handshake" theory for the engineering vehicle ECUs. The fault is determined by the "handshake" theory between the host computer and the ECU. In addition, the paper also designs the fault detection system based on LabVIEW. Experimental results show that this method can detect the type of CAN fault in given simulation environment.

In this paper, the introduction of the new OS kernel internals for the new metrics for the grid and cloud performance prediction is explained. This new introduction is named as Division of Load (DOL). The DOL method breaks down the CPU load by individual users and then separates the Disk IO load from the CPU load. In the first part, the concepts of the load signals are shown theoretically and experimentally as these metrics are introduced into the kernel for the first time. In the second part, the required code changes which are introduced to the OS kernel are discussed. The separation will help to collect the computer loads separately for individual users as CPU loads and Disk IOs loads. Such a move will open Grid, Cluster and Cloud Performance Predictors to use the divided data archives for better predictability of both CPU and Disk IO loads. Many existing Grid and Cloud resource prediction engines are going to be advantaged by this data purification and specialization.
在本文中,介绍了新的操作系统内核内部的网格和云性能预测的新指标。这一新的引入被命名为负载划分(DOL)。DOL方法按单个用户分解CPU负载,然后将磁盘IO负载从CPU负载中分离出来。在第一部分中,首次将负载信号的概念引入内核,从理论上和实验上展示了这些指标的概念。在第二部分中,讨论了引入OS内核所需的代码更改。这种分离将有助于为单个用户分别收集计算机负载,如CPU负载和磁盘IOs负载。这样的举动将打开网格、集群和云性能预测器,使用划分的数据存档,以更好地预测CPU和磁盘IO负载。许多现有的网格和云资源预测引擎将受益于这种数据净化和专业化。

In marine navigation, we need to calculate the maneuver scheme of ships. The existing solution is lack of intelligence, which generally use the method of manual drawing for calculation, is also inevitably to increase the cost of manpower and time. For solving this problem, this paper proposes a ship maneuvering algorithm based on triangle transformation, which includes three aspects of approach maneuver, occupation position maneuver and avoidance maneuver. The algorithm takes the relative bearing, speed and position of target ship as inputs, predicts the relative bearing and the time required to complete the maneuver, and provides the support of decision for maritime tactical operations. Finally, the algorithm is implemented by Java programming language and simulated in all directions by MATLAB. The results show that the ship maneuvering scheme predicted by this method has a good fit with the actual situation, which verifies that the proposed algorithm has higher reliability and effectiveness.
在海上航行中,需要对船舶的机动方案进行计算。现有的解决方案缺乏智能化,一般采用人工绘图的方法进行计算,也不可避免地增加了人力和时间的成本。为了解决这一问题,本文提出了一种基于三角变换的船舶机动算法,该算法包括接近机动、占据位置机动和回避机动三个方面。该算法以目标舰船的相对方位、航速和位置为输入,预测目标舰船的相对方位和完成机动所需的时间,为海上战术作战提供决策支持。最后,用Java编程语言对算法进行了实现,并用MATLAB进行了全方位的仿真。结果表明,该方法预测的船舶机动方案与实际情况吻合较好,验证了所提算法具有较高的可靠性和有效性。
