Personal route prediction (PRP) has attracted much research interest recently because of its technical challenges and broad applications in intelligent vehicle and transportation systems. Traditional navigation systems generate a route for a given origin and destination based on either shortest or fastest route schemes. In practice, different people may very likely take different routes from the same origin to the same destination. Personal route prediction attempts to predict a driver's route based on the knowledge of driver's preferences. In this paper we present an intelligent personal route prediction system, I_PRP, which is built based upon a knowledge base of personal route preference learned from driver's historical trips. The I_PRP contains an intelligent route prediction algorithm based on the first order Markov chain model to predict a driver's intended route for a given pair of origin and destination, and a dynamic route prediction algorithm that has the capability of predicting driver's new route after the driver departs from the predicted route.

To assess the performance of a network system against disturbances, existing methods are usually concerned with two different extreme situations: (i) how likely the system will degrade into some separated sub-graphs because of disturbances; (ii) how likely the 1st best paths will be cut off by disturbances. However, a more general situation, i.e., how likely those paths whose lengths are within a given range will be affected by disturbances, is barely discussed. Basically, to address this general situation, all (not just a proportion) of those paths whose lengths are within the given range must be found out between all pairs of origin and destination (OD) of interest. Unfortunately, no effective method has ever been reported to accomplish this task, although there are many methods capable of calculating all the 1st best paths between all OD pair of interest. This paper, for the first time, attempts to address the above general situation of network performance assessment. To this end, a novel ripple-spreading algorithm (RSA) is proposed to carry out a ripple relay race on the network, in order to identify all of those paths whose lengths are within the given range. Surprisingly, the proposed RSA can find all such paths between all OD pairs of interest by just a single run of ripple relay race. This work makes progress towards the general performance assessment of a network system against disturbances.

Organizations rely on security experts to improve the security of their systems. These professionals use background knowledge and experience to align known threats and vulnerabilities before selecting mitigation options. The substantial depth of expertise in any one area (e.g., databases, networks, operating systems) precludes the possibility that an expert would have complete knowledge about all threats and vulnerabilities. To begin addressing this problem of fragmented knowledge, we investigate the challenge of developing a security requirements rule base that mimics multi-human expert reasoning to enable new decision-support systems. In this paper, we show how to collect relevant information from cyber security experts to enable the generation of: (1) interval type-2 fuzzy sets that capture intra- and inter-expert uncertainty around vulnerability levels; and (2) fuzzy logic rules driving the decision-making process within the requirements analysis. The proposed method relies on comparative ratings of security requirements in the context of concrete vignettes, providing a novel, interdisciplinary approach to knowledge generation for fuzzy logic systems. The paper presents an initial evaluation of the proposed approach through 52 scenarios with 13 experts to compare their assessments to those of the fuzzy logic decision support system. The results show that the system provides reliable assessments to the security analysts, in particular, generating more conservative assessments in 19% of the test scenarios compared to the experts' ratings.

Image segmentation is an important preprocessing step in many computer vision applications, using the image thresholding as one of the simplest and the most applied methods. Since the optimal thresholds' selection can be regarded as an optimization problem, it can be found easily by applying any meta-heuristic with an appropriate objective function. This paper investigates the impact of different chaotic maps, embedded into a self-adaptive differential evolution for the purpose of image thresholding. The Kapur entropy is used as an objective function that maximizes the entropy of different regions in the image. Three chaotic maps, namely the Kent, Logistic and Tent, found commonly in literature, are studied in this paper. The applied chaotic maps are compared to the original differential evolution, self-adaptive differential evolution, and the state-of-the-art L-Shade tested on four images. The results show that the applied chaotic maps improve the results obtained using the traditional randomized method.

This study presents an application of the Multiple Worlds Model of Evolution. The goal is to model radio stations in a given market. The model captures listener demographics and maximizes listeners, while securing advertising revenue. Listener preferences for different types of content are set as positive (like) and negative (dislike) integers, allowing surveys of the demographic to act as the model parameters directly. Fitness evaluation is performed with a modeled hour of radio playtime where stations can select between a set of content types and advertisements. Advertisements provide fitness in the form of advertising revenues; however, listeners will only stay on a station which provides content they enjoy. The Multiple Worlds Model is a form of multiple population evolutionary algorithm. It evaluates fitness based on the actions of one member from each population, and has no genetic transfer of information between populations. Each population can thus specialize. In the current study, such specialization is a self-organization of focused (e.g. rock or country) stations via adaption to listener preferences. The model is examined using different numbers of independent populations with even splits among demographic types. The evolved stations show differences in playlists where the profiles differ in their enjoyments and convergence between stations where the listener profiles are similar.

Fitness landscape analysis encompasses a selection of techniques designed to estimate the properties of a search landscape associated with an optimisation problem. Applied to neural network training, fitness landscape analysis can be used to establish the link between the shape of the objective function and various neural network design and architecture properties. However, most fitness landscape analysis metrics rely on search space sampling. Since neural network search space is unbounded, it is unclear what subset of the search space should be sampled to obtain representative measurements. This study analyses fitness landscape properties of neural networks under various search space boundaries, and proposes meaningful search space bounds for neural network fitness landscape analysis.

Time series forecasting constitutes an important aspect of any kind of technical system, since the underlying stochastic processes vary over time. Extensive efforts for designing self-adaptive learning systems have been made, to take system designers out of the loop. One goal of such systems is to transfer design-time decisions, e.g. parametrisation, to the run-time. By means of forecasting the succeeding system state, the system itself is enabled to anticipate, how to reconfigure to handle upcoming conditions. Ensemble forecasting is a specific means of combining and weighting the forecasts of multiple independent forecast methods. This concept has proven successful in various domains today. In this work, we present our self-adaptive forecast module for ensemble forecasting of univariate time series and draw a picture of how the eXtended Classifier System for Function approximation (XCSF) can be utilised as a novel weighting approach in this context. We elaborate on the fundamental ideas and evaluate our proposed technique on the basis of several time series with different characteristics.

We investigate the use of deep artificial neural networks to approximate the optimal state-feedback control of continuous time, deterministic, non-linear systems. The networks are trained in a supervised manner using trajectories generated by solving the optimal control problem via the Hermite-Simpson transcription method. We find that deep networks are able to represent the optimal state-feedback with high accuracy and precision well outside the training area. We consider non-linear dynamical models under different cost functions that result in both smooth and discontinuous (bang-bang) optimal control solutions. In particular, we investigate the inverted pendulum swing-up and stabilization, a multicopter pin-point landing and a spacecraft free landing problem. Across all domains, we find that deep networks significantly outperform shallow networks in the ability to build an accurate functional representation of the optimal control. In the case of spacecraft and multicopter landing, deep networks are able to achieve safe landings consistently even when starting well outside of the training area.

The energy trading in Brazil is conducted in two different environments: the Free Market (ACL) and the Regulated Market (ACR). In ACL, the free and specials consumers can freely negotiate their own energy. In contrast, the captive consumers belong to ACR, and do not have the option to choose their energy supplier. Germany also has a similar system, where the big consumers (industrial) can freely negotiate their energy and the small consumers (residential) must choose a provider and pay a fixed price for the energy, where prices vary very little from one provider to another. Recently in Brazil, it was created the white tariff providing conditions that stimulate some consumers to shift consumption from peak periods to those periods that the distribution network has idle capacity. Regarding distributed energy resources (DER), there are also some peculiarities between the two countries. The objective of this paper is to verify the impacts that German residential consumers and the distribution network would have with the implementation of an hourly tariff equivalent to the white tariff of Brazil. The tariff structure and energy market regulation from both countries are compared and several simulations considering real data from German consumers and tariffs are done.

This paper describes an plane extraction method using point cloud data to perceive an unknown object for a service robot. Recently, depth sensors are used to perceive 3D space for a robot. A depth sensor have been used to recognize unknown environment, such as surface reconstruction, model fitting and so on. Point Cloud Library is typical open source library to deal with 3D point cloud data. However, robot perception for grasping have limitations with high computational costs and low-accuracy for perceiving small objects. Therefore, we propose the PSO-based plane detection method with RG to reconstruct an object from a combination of detected planes. To verify accuracy and computational cost for the plane detection of unknown object, we show that the proposed method has higher accuracy and less computational cost for the proposed method.
