Biological and biomedical research are increasingly driven by experimental techniques that challenge our ability to analyse, process and extract meaningful knowledge from the underlying data. the impressive capabilities of next-generation sequencing technologies, together with novel and constantly evolving, distinct types of omics data technologies, have created an increasingly complex set of challenges for the growing fields of Bioinformatics and Computational Biology. the analysis of the datasets produced and their integration call for new algorithms and approaches from fields such as databases, Statistics, data Mining, Machine learning, Optimization, Computer Science and Artificial Intelligence. Clearly, Biology is more and more a science of information and requires tools from the computational sciences. In the last few years, we have seen the rise of a new generation of interdisciplinary scientists with a strong background in the biological and computational sciences. In this context, the interaction of researchers from different scientific fields is, more than ever, of foremost importance in boosting the research efforts in the field and contributing to the education of a new generation of Bioinformatics scientists. the PACBB17 conference was intended to contribute to this effort and promote this fruitful interaction, with a technical program that included 39 papers spanning many different sub-fields in Bioinformatics and Computational Biology. Further, the conference promoted the interaction of scientists from diverse research groups and with a distinct background (computer scientists, mathematicians, biologists).

Dynamic or time-varying data analysis is of great interest in emerging and challenging research on automation and machine learning topics. In particular, motion segmentation is a key stage in the design of dynamic data analysis systems. Despite several studies have addressed this issue, there still does not exist a final solution highly compatible with subsequent clustering/classification tasks. In this work, we propose a motion segmentation compatible with kernel spectral clustering (KSC), here termed KSC-MS, which is based on multiple kernel learning and variable ranking approaches. Proposed KSC-MS is able to automatically segment movements within a dynamic framework while providing robustness to noisy environments.

Network traffic classification technique is currently a key part of network security systems. In recent years, some network traffic classification algorithms using machine learning based on packet and flow level features have been proposed, yet the results are frequently disappointing. On the one hand, obtaining a large, representative, training data set that is fully labeled to train a classifier is difficult, time-consuming, and expensive. On the other hand, the classification performance is affected by the new protocols and applications which can produce unknown traffic that existing classification systems cannot identify. To achieve effective and inexpensive classification, we propose a framework based on unsupervised methods and the tri-training method. By two independent clusterings, the proposed method can precisely detect unknown applications and extend labeled flows from a few labeled and many unlabeled flows. Meanwhile, tri-training method can effectively exploit unlabeled flows to enhance the proposed method performance. We implement our approach and evaluate it on two real-world Internet traffic traces. the experimental results demonstrate that the proposed method has more excellent performance in terms of Precision and Recall in comparison withthe state-of-the-art approaches and can better handle different data sets.

Higher performance is the eternal purpose for super-resolution (SR) methods to pursue. Since the deep convolution neural network is introduced into this issue successfully, many SR methods have achieved impressive results. To further improve the accuracy that current SR methods have achieved, we propose a high-accuracy deep convolution network (HDCN). In this article, deeper network structure is deployed for reconstructing images with a fixed upscaling factor and the magnification becomes alternative by cascading HDCN. L-2 loss function is substituted by a more robust one for reducing the blurry prediction. In addition, gradual learning is adopted for accelerating the rate of convergence and compacting the training process. Extensive experiment results prove the effectiveness of these ingenious strategies and demonstrate the higher-accuracy of proposed model among state-of-the-art SR methods.

Large-scale classification is one of the most significant topics in machine learning. However, previous classification methods usually require the assumption that the data has a balanced class distribution. thus, when dealing with imbalanced data, these methods often present performance degradation. In order to seek the better performance in large-scale classification, we propose a novel Cost-Sensitive Alternating Direction Method of Multipliers method (CSADMM) to deal with imbalanced data in this paper. CSADMM derives the problem into a series of subproblems efficiently solved by a dual coordinate descent method in parallel. In particular, CSADMM incorporates different classification costs for large-scale imbalanced classification by cost-sensitive learning. Experimental results on several large-scale imbalanced datasets show that compared with distributed random forest and fuzzy rule based classification system, CSADMM obtains better classification performance, withthe training time is significantly reduced. Moreover, compared with single-machine methods, CSADMM also shows promising results.

Advanced energy management control systems (EMCS), or building automation systems (BAS), offer an excellent means of reducing energy consumption in heating, ventilating, and air conditioning (HVAC) systems while maintaining and improving indoor environmental conditions. this can be achieved through the use of computational intelligence and optimization. this paper evaluates model-based optimization processes (OP) for HVAC systems utilizing any computer algebra system (CAS), genetic algorithms and self-learning or self-tuning models (STM), which minimizes the error between measured and predicted performance data. the OP can be integrated into the EMCS to perform several intelligent functions achieving optimal system performance. the development of several self-learning HVAC models and optimizing the process (minimizing energy use) is tested using data collected from an actual HVAC system. Using this optimization process (OP), the optimal variable set points (OVSP), such as supply air temperature (Ts), supply duct static pressure (Ps), chilled water supply temperature (Tw), minimum outdoor ventilation, and chilled water differential pressure set-point (Dpw) are optimized with respect to energy use of the HVAC's cooling side including the chiller, pump, and fan. the optimized set point variables minimize energy use and maintain thermal comfort incorporating ASHRAE's new ventilation standard 62.1-2013. this research focuses primarily with: on-line, self-tuning, optimization process (OLSTOP);HVAC design principles;and control strategies within a building automation system (BAS) controller. the HVAC controller will achieve the lowest energy consumption of the cooling side while maintaining occupant comfort by performing and prioritizing the appropriate actions. the program's algorithms analyze multiple variables (humidity, pressure, temperature, CO2, etc.) simultaneously at key locations throughout the HVAC system (pumps, cooling coil, chiller, fan, etc.) to reach the fun

the majority of scheduling metaheuristics use indirect representation of solutions as a way to efficiently explore the search space. thus, a crucial part of such metaheuristics is a "schedule generation scheme" - procedure translating the indirect solution representation into a schedule. Schedule generation scheme is used every time a new candidate solution needs to be evaluated. Being relatively slow, it eats up most of the running time of the metaheuristic and, thus, its speed plays significant role in performance of the metaheuristic. Despite its importance, little attention has been paid in the literature to efficient implementation of schedule generation schemes. We give detailed description of serial schedule generation scheme, including new improvements, and propose a new approach for speeding it up, by using Bloom filters. the results are further strengthened by automated control of parameters. Finally, we employ online algorithm selection to dynamically choose which of the two implementations to use. this hybrid approach significantly outperforms conventional implementation on a wide range of instances.

In this paper a conflict-free data aggregation problem, known as a Convergecast Scheduling Problem, is considered. It is NP-hard in the arbitrary wireless network. the paper deals with a special case of the problem when the communication graph is a square grid with unit cells and when the transmission range is 2 (in L-1 metric). Earlier for the case under consideration we proposed a polynomial time algorithm with a guaranteed accuracy bound. In this paper we have shown that the proposed algorithm constructs an optimal solution to the problem.
