As cloud based platforms become more popular, it becomes an essential task for the cloud administrator to efficiently manage the costly hardware resources in the cloud environment. Prompt action should be taken whenever hardware resources are faulty, or configured and utilized in a way that causes application performance degradation, hence poor quality of service. In this paper, we propose a semantic aware technique based on neural network learning and patternrecognition in order to provide automated, real-time support for resource anomaly detection. We incorporate application semantics to narrow down the scope of the learning and detection phase, thus enabling our machine learning technique to work at a very low overhead when executed online. As our method runs "life-long" on monitored resource usage on the cloud, in case of wrong prediction, we can leverage administrator feedback to improve prediction on future runs. this feedback directed scheme withthe attached context helps us to achieve an anomaly detection accuracy of as high as 98.3% in our experimental evaluation, and can be easily used in conjunction with other anomaly detection techniques for the cloud.

the article is focused on a particular aspect of classification, namely the imbalance of recognized classes. the paper contains a comparative study of results of musical symbols classification using known algorithms: k-nearest neighbors, k-means, Mahalanobis minimal distance, and decision trees. Authors aim at addressing the problem of imbalanced patternrecognition. First, we theoretically analyze difficulties entailed in the classification of music notation symbols. Second, in the enclosed case study we investigate the fitness of named single classifiers on real data. Conducted experiments are based on own implementations of named algorithms with all necessary image processing tasks. Results are highly satisfying.

Proposed method, called Probabilistic Nodes Combination (PNC), is the method of 2D curve modeling and interpolation using the set of key points. Nodes are treated as characteristic points of unknown object for modeling and recognition. Identification of shapes or symbols need modeling and each model of the pattern is built by a choice of probability distribution function and nodes combination. PNC modeling via nodes combination and parameter. as probability distribution function enables curve parameterization and interpolation for each specific object or symbol. Two-dimensional curve is modeled and interpolated via nodes combination and different functions as continuous probability distribution functions: polynomial, sine, cosine, tangent, cotangent, logarithm, exponent, arc sin, arc cos, arc tan, arc cot or power function.

this paper presents a new flexible approach to predict the gender of the writers from their handwriting samples. Handwriting features can be extracted from different methods. therefore, the multi-feature sets are irrelevant and redundant. the conflict of the features exists in the sets, which affects the accuracy of classification and the computing cost. this paper proposes a Mutual Information (MI) approach, that focuses on feature selection. the approach can decrease redundancies and conflicts. In addition, it extracts an optimal subset of features from the writing samples produced by male and female writers. the classification is carried out using a Support Vector Machine (SVM) on two databases. the first database comes from the ICDAR 2013 competition on gender prediction, the other database contains the Registration Document-Form (RDF) database in Chinese. the proposed and compared methods were evaluated on both databases. Results from the methods highlight the importance of feature selection for gender prediction from handwriting.

Determining the appropriate data window size for online sensor data streams to recognize a specific activity is still a challenging task. In particular, when new sensor events are recorded. this paper proposes a windowing algorithm which presents promising results to recognize complex activities, e.g., in a smart home environment. the underlying basic idea is to analyze the sensor data in order to identify the set of "best fitting sensors": it contains those sensors that most contribute to the recognition task, and therefore should be considered in a window. To validate our approach, we applied it on the CASAS data set which is an international data set for activity recognition. Based on the promising results, we believe that this algorithm can assist to detect human activities. thus, our approach might be used in Active and Assisted Living Environments (AAL), where activity recognition is required to distinguish the types of help, a person needs to master his/her daily life activities.

the main objective of this paper is a texture-based solution to the problem of acute stroke tissue recognition on computed tomography images. Our proposed method of early stroke indication was based on two fundamental steps: (i) segmentation of potential areas with distorted brain tissue (selection of regions of interest), and (ii) acute stroke tissue recognition by extracting and then classifying a set of well-differentiating features. the proposed solution used various numerical image descriptors determined in several image transformation domains: 2D Fourier domain, polar 2D Fourier domain, and multiscale domains (i. e., wavelet, complex wavelet, and contourlet domain). the obtained results indicate the possibility of relatively effective detection of early stroke symptoms in CT images. Selected normal or pathological blocks were classified by LogitBoost withthe accuracy close to 75% withthe use of our adjusted cross-validation procedure.

In this paper, an improved classification method NCEEP based on EP is proposed, and this algorithm is improved on the basis of the original CEEP classification algorithm. In this paper also cited a optimal discretization method to discretize pre process data set, and select the most effective minimum support and minimum growth rate threshold. Experiments on the data set in the UCI machine learning database show that the efficiency of the improved classification algorithm proposed in this paper is obviously improved.
