In last decade, there has been explosive growth in multimedia technologies and its applications. For fast transmission, compression of image data is necessary. Due to this images are lead to distortion like blocking, ringing and blurring. the channel noise also gets introduced if transmitted over communication channel. Due to the distortion, image quality assessment plays an important role. In majority applications, original image is not available for reference. In such application, the metric which evaluates quality without reference is called "no reference quality" metric. Since human perception has limitation and in automated quality assessment applicationthere is an immense need of developing no reference quality assessment framework. In this paper, we propose no reference image quality assessment scheme using the machinelearning approach. Based on the degradation such as blocking, ringing artifacts, the related features such as average absolute difference between in-block image sample and zero-crossing rate, spatial frequency measure and spatial activity measures are computed for JPEG gray scale images. the earlier related work uses such parameters and mathematical predictors. Many time the correlation of extracted features, DMOS and output of predictor do not present correct assessment. In the proposed approach, properly trained back propagation artificial neural network with MOS as target is used. the result indicates that accuracy of quality assessment is better.

the article presents an application of Adaptive Splitting and Selection (AdaSS) classifier in the medical decision support system for breast cancer diagnosis. Apart from the canonical malignant versus nonmalignant problem we introduced a third class - fibroadenoma, which is a benign tumor of the breast often occurring in women. Medical images are delivered by the Regional Hospital in Zielona Gora, Poland. For the process of segmentation and feature extraction a mixture of Gaussians is used. AdaSS is a combined classifier, based on an evolutionary splitting of feature space into clusters. To increase the overall accuracy of the classification we propose to add a feature selection step to the optimization criterion of the native AdaSS algorithm. Experimental investigation proves that the introduced method is more accurate than previously used classification approaches.

In many domains such as Telecom various scenarios necessitate the processing of large amounts of data using statistical and machinelearning algorithms. A noticeable effort has been made to move the data management systems into MapReduce parallel processing environments such as Hadoop and Pig. Nevertheless these systems lack the features of advanced machinelearning and statistical analysis. Frame-works such as Mahout on top of Hadoop support machinelearning but their implementations are at the preliminary stage. For example Mahout does not provide Support Vector machine (SVM) algorithms and it is difficult to use. On the other hand traditional statistical software tools such as R containing comprehensive statistical algorithms for advanced analysis are widely used. But such software can only run on a single computer and therefore it is not scalable. In this paper we propose an integrated solution RPig which takes the advantages of R (for machinelearning and statistical analysis capabilities) and parallel data processing capabilities of Pig. the RPig framework offers a scalable advanced data analysis solution for machinelearning and statistical analysis. Analysis jobs can be easily developed with RPig script in high level languages. We describe the design implementation and an eclipse-based RPigEditor for the RPig framework. Using application scenarios from the Telecom domain we show the usage of RPig and how the framework can significantly reduce the development effort. the results demonstrate the scalability of our framework and the simplicity of deployment for analysis jobs.

the overview presents the development and application of Hierarchical Temporal Memory (HTM). HTM is a new machinelearning method which was proposed by Jeff Hawkins in 2005. It is a biologically inspired cognitive method based on the principle of how human brain works. the method invites hierarchical structure and proposes a memory-prediction framework, thus making it able to predict what will happen in the near future. this overview mainly introduces the developing process of HTM, as well as its principle, characteristics, advantages and applications in vision, image processing and robots movement, some potential applications by using HTM , such as thinking process, are also put forward.
