Conventional methods predict emotion directly by measuring equipment like electrode. However, this approach is not suitable for education, especially for children. In this paper, we propose modular Bayesian networks for predicting the emotion with the environment information from the sensors. The Bayesian network is constructed as modules divided by Markov boundary. To evaluate the proposed method, we use data collected from kindergarten classes. The results show more than 84% accuracy and 20 times faster than the single Bayesian network.

This paper presents an analysis of the impact of the parameters of an Echo State Network (ESN) on its performance. In particular, we are interested on the parameter behaviour when the model is used for forecasting pseudo-periodic time series. According previous literature, the spectral radius of the hidden-hidden weight matrix of the ESN is a relevant parameter on the model performance. It impacts in the memory capacity and in the accuracy the model. Small values of the spectral radius are recommended for modelling time-series that require short fading memory. On the other hand, a matrix with spectral radius close to the unity is recommended for processing long memory time series. In this article, we figure out that the periodicity of the data is also an important factor to consider in the design of the ESN. Our results show that the better forecasting (according to two metrics of performance) occurs when the hidden-hidden weight matrix has spectral value equal to 0.5. For our analysis we use a public synthetic dataset that has a high periodicity.

In this paper, an approach of QR code detection using histograms of oriented gradients (HOG) and AdaBoost is proposed. There are two steps in our approach. In the first step, feature vectors are extracted using HOG with various cell sizes and overlapping or non-overlapping blocks. In the second step, the AdaBoost algorithms are trained by the input feature vectors from HOG and output targets. The QR code position is then detected via the predicted outputs from the AdaBoost algorithm. Experimental results show that the proposed method is an effective way to detect QR code position. Frankly speaking, the results reported here only provide preliminary study on QR code detection using HOG and AdaBoost.

The goal of this paper is to introduce a task of image plagiarism detection. More specifically, we propose a method of searching for a plagiarized image in a database. The main requirements for searching in the database are computational speed and success rate. The proposed method is based on the technique of F-transform, particularly Fs-transform, s ≥ 0. This technique significantly reduces the domain dimension and therefore, is speeds-up the whole process. we present several experiments and measurements which prove the speed and accuracy of our method. We also propose examples to demonstrate an ability of using this method in many applications.

In this paper, a proposed system for feature selection based on social spider optimization (SSO) is proposed. SSO is used in the proposed system as searching method to find optimal feature set maximizing classification performance and mimics the cooperative behavior mechanism of social spiders in nature. The proposed SSO algorithm considers two different search agents (social members) male and female spiders, that simulate a group of spiders with interaction to each other based on the biological laws of the cooperative colony. Depending on spider gender, each spider (individual) is simulating a set of different evolutionary operators of different cooperative behaviors that are typically found in the colony. The proposed system is evaluated using different evaluation criteria on 18 different datasets, which compared with two common search methods namely particle swarm optimization (PSO), and genetic algorithm (GA). SSO algorithm proves an advance in classification performance using different evaluation indicators.

The development of equipment that measures EEG signals leads to the research that applies them to many domains. There are active research going on EEG signals for shared vehicle control system between human and car. An appropriate filtering method is also important because EEG signals normally have lots of noises. To reduce such noises, full matrix filter, sparse matrix reference filter, and common average reference (CAR) filter are presented and analyzed in this paper. In order to develop shared vehicle control system, we use controller, brain-computer interface (BCI), EEG signals, and car simulator program. By executing t-test, it was possible to find the optimal filter out of three filters mentioned above. With the analysis of t-test, it has revealed that full matrix filter is not appropriate for shared vehicle control system. In addition, it proves CAR filter has the best performance among these filters.

The automatic assessment of online review's quality is becoming important with the number of reviews increasing rapidly. In order to help determining review's quality, some online services provide a system where users can evaluate or feedback the helpfulness of review as crowdsourcing knowledge. This approach has shortcomings of sparse voted data and richer-get-richer problem in which favor reviews are voted frequently more than others. In this work, we use Latent Dirichlet Allocation (LDA) method to exploit hidden topics distribution information of all reviews and propose supervisor prediction model based on probabilistic meaning of the review's quality. We also propose a deep neural network to classify the review in quality and validate our proposals within some real reviews datasets. We demonstrate that using hidden topics distribution information could be helpful to improve the accuracy of review quality prediction and classification.

This paper describes ongoing study and first results on the application of Neuro-Fuzzy (NF) to support large-scale forensics investigation in the domain of Network Forensics. In particular we focus on patterns of benign and malicious activity that can be find in network traffic dumps. We propose several improvements to the NF algorithm that results in proper handling of large-scale datasets, significantly reduces number of rules and yields a decreased complexity of the classification model. This includes better automated extraction of rules parameters as well as bootstrap aggregation for generalization. Experimental results show that such optimization gives a smaller number of rules, while the accuracy increases in comparison to existing approaches. In particular, it showed an accuracy of 98% when using only 39 rules. In our research we contribute to forensics science by increasing awareness and bringing more comprehensive fuzzy rules. During the last decade many cases related to network forensics resulted in data that can be related to Big Data due to its complexity. Application of Soft Computing methods, such that Neuro-Fuzzy may bring not only sufficient classification accuracy of normal and attack traffic, yet also facilitate in understanding traffic properties and developing a decision-support mechanism.

This paper presents a fast algorithm for ground segmentation that quickly and accurately differentiates ground points from obstacles after processing unstructured point clouds. Unlike most recent approaches found in the literature, it does not rely on any sensor-specific feature or data ordering. It performs an orthogonal projection into the horizontal plane followed by a top-down 4-ary tree segmentation. The segmentation self-adapts to the point cloud, focusing processing effort on detailed areas. This adaptive subdivision process allows successfully extracting ground points even when the floor is not perfectly flat. Finally, tests demonstrate real-time performance for execution in low cost embedded devices.

. This study proposes a new algorithm for leaf shape identification of medicinal leaves based on curvilinear shape descriptor. Leaf shape is a very discriminating feature for identification. The proposed approach is introduced to recognize and locate points of local maxima from smooth curvature and also to reduce contour points in order to optimize the efficiency of leaf shape identification. Experiments were conducted on six shapes of medicinal leaves, i.e lanceolate, ovate, obovate, reniform, cordate, and deltoid. We extracted five shape descriptors of leaf shape curvature: salient points' position, centroid distance, extreme curvature, angle of curvature, and slope of salient points. The experimental results show that the proposed algorithm can extract the shape descriptors for leaf shape identification. Moreover, the experimental results indicated that the fusion of shape descriptors outperform than using single shape descriptor with accuracy 72.22%.
