In this study, we propose a method to automatically remove utility poles and electric parts from 3D measurement data of shopping streets and roads, and be used for the landscape simulation of underground utility poles construction at Suehiro-cho of Miyako City. In this method, utility poles were stably extracted automatically by using plural rectangular volumes, Hough transform, and two-dimensional Gaussian function. The efficiency of processing is improved by five times compared with the interactive method of removing the utility poles and the electric parts by the dialogue processing.

In this research, an enhanced invasive weed optimization (EIWO) has been proposed to solve resource-constrained project scheduling problem (RCPSP) which subjects to the makespan minimization. Firstly, a hybrid population initialization method is illustrated to improve the quality of initial solutions. Secondly, to enhance the local exploitation ability, a local search approach is embedded in the spatial dispersal process. Thirdly, an improved competitive exclusion based on acceptance probability is proposed. At the end of this article, EIWO is tested and verified by standard benchmark problems from PSPLIB. Compared with the existing algorithms through computer numerical experiments, the new EIWO algorithm is more effective and efficient in solving RCPSP.

Integration of the line laser scanning system with visual SLAM for 3D mapping is conceptually attractive yet facing the difficulty with processing projected line laser, which is not only hard to be extracted from images captured under natural light, but also disrupts the feature tracking procedure in visual SLAM. This paper proposes a method of segmenting the target object and extracting the laser line to build an accurate and realistic 3D model by using a semantic segmentation method. First, we introduce adaptive thresholds for the recognized objects to solve the laser extraction problem. Second, we discard the extracted image features in the laser area for better pose estimation of visual SLAM. Finally, we complement the surface of lasers with the color information in the related objects of 3D mapping. In our experiments, we show that the proposed method can produce a dense colored 3D mapping and has higher performance than the traditional visual SLAM based laser scanning system.

Incident Management is a part of managing IT services, improving services, and achieving organizational goals. IT incidents can be learned and predicted future incidents. This research compares the factors that cause incidents using initial machine learning techniques such as Random Forest, SVM, Multilayer perceptron, and the latest machine learning techniques such as RNN, LSTM, GRU, to predict IT incidents. Grid search is used to find the optimal parameter combination. 5-fold and 10-fold Cross-validation evaluates the model's optimal performance by dividing the dataset into training data and test data. The results show that the highest accuracy of 98.866% is produced by LSTM machine learning techniques at 5-fold and 10-fold cross-validation. SVM has the lowest accuracy of 97.837% made at 5-fold and 10-fold cross-validation.

This research is mainly about the prediction of the price change in the stock market. Instead of daily change, this paper analyzes the trend of price change for weeks by judging turning points. Deep neural networks will be used as the classifier of true and fake golden crosses to judge the growth trend of price change. Most stocks on the sample list have positive profits after simulated trading of 10 years. Based on the results we may conclude that deep neural networks are helpful to assist users positively for stock investment.

Ocean wave spectrum are mainly estimated from wave surface records, and traditional methods involve physically-based modeling of wave dynamics and frequency analysis. In this paper, we employ machine learning strategy and propose a Seq2Seq (sequence to sequence) model which connects the encoder and decoder with an attention mechanism. This model can both effectively predict wave spectrum and be easily implemented. Experiments on numerical simulations show the feasibility of the proposed model in wave spectrum estimation and the accuracy comparing with traditional methods.

Migraine without aura (MwoA) is the most typical migraine disease in the clinic, which is endangered to human health and challenging to diagnose. Developing the auxiliary diagnosis algorithms of MwoA based on functional connectivity (FC) changes from resting-state functional magnetic resonance imaging (rs-fMRI) is an important research domain. However, existing auxiliary diagnostic methods mainly adopt a seed-based correlation method to extract FC, which are easily affected by subjective factors. Moreover, those methods neglect the relationship between changes in FC and disease duration. In this paper, we report a weakly supervised learning method aiming to tackle those issues. We propose a resting-state brain network-based 3D deep multiple instance learning with spatial attention mechanism (R3D-DMILSAM) framework, where the patient-level label is allocated to the rs-fMRI data that view as multiple instances of a bag. R3D-DMILSAM uses the group information guided independent component analysis (GIG-ICA) to generate the subject-specific resting-state brain networks (RSNs). After that, the designed spatial attention-based 3D deep multiple instance learning (SA3D-DMIL) is trained to perform the diagnosis of MwoA. SA3D-DMIL can automatically generate several semantic deep instances and discovers abnormal RSNs using spatial attention mechanism. Extensive experimental results on the MwoA dataset show that R3D-DMILSAM achieves an overall accuracy of 88.80% and AUC of 94.70%. The visual network obtains high weight, which could be used as a potential biomarker for individualized diagnosis of MwoA.

The skeleton analysis introduced by Kinect has been an efficient way for interaction. Skeleton analysis interaction is more intuitive and aligns better with human natural behaviors compared with traditional approaches. However, skeleton analysis often has the problem of producing conflict gesture identifications if two interaction movements are similar. Additionally, it always mistakenly recognizes some unconscious or intentional body movements as positive gestures. To this end, we proposed a new interaction method enhanced by both vision algorithms and deep learning. An improved residual neural network is employed to recognize gestures which are then used for distinguishing similar body movements. A combined human-computer interaction scheme is proposed which includes three main components: (a) a hand shape segmentation approach enhanced by skin color detection and skeleton joint tracking, (b) the deep learning augmented detection for changes of gestures and (c) a deep learning-based gesture command recognition for robot control. Experiments are conducted using the proposed method for robot interaction. The results demonstrate that unconscious body movements can be accurately identified. Similar body movements can also be distinguished robustly. The proposed method can run in real-time with competitive performance.

The laser line rotating-scan system has been a popular method for 3D reconstruction. But the rotating axis of the scanner usually does not coincide with the camera origin point, which makes this technique a bit more complex. This paper proposes a rotation axis calibration method to solve the problem for more accurate 3D imaging. The calibration parameters are defined as the external parameters (rotation and translation) between the camera coordinate system and the world coordinate system of the rotation axis. With the rotation axis calibration, 3D results of a single frame are transformed into the world coordinate system of the rotation axis. Finally, we realize multi-frame splicing only with the rotation angle provided by the scanner. Experiments on real data show our method is basically correct and practical.

In recent years, investment strategies on financial markets using deep learning have attracted a significant amount of research attention. The objective of these studies is to obtain investment action that has a low risk and increases profit. On the other hand, Distributional Reinforcement Learning (DRL) expands the action-value function to a discrete distribution in reinforcement learning, which can control risk. However, DRL has not yet been used to learn investment action. In this study, we construct a low-risk investment trading model using DRL. This model is backtested on Nikkei 225 dataset and compared with Deep Q Network (DQN). We evaluate performance in terms of final asset amounts, their standard deviation, and the Sharpe ratio. The experimental results show that the proposed DRL-based method can learn low-risk actions with increasing profit, outperforming the compared method DQN.
