    Generative models have been in existence for many decades. In the field of machine learning, we come across many scenarios when directly learning a target is intractable through discriminative models, and in such cases the joint distribution of the target and the training data is approximated and generated. These generative models help us better represent or model a set of data by generating data in

    A network is a typical expressive form of representing complex systems in terms of vertices and links, in which the pattern of interactions amongst components of the network is intricate. The network can be static that does not change over time or dynamic that evolves through time. The complication of network analysis is different under the new circumstance of network size explosive increasing. In

    Knowing code clones (similar code fragments) is helpful in software maintenance and re-engineering. As clone detectors return huge numbers of clones, visualization techniques have been proposed to make cloning information more comprehensible and useful for programmers. We present a mapping study of clone visualization techniques, classifying visualizations in respect to the user goals to be achieved

  • Multidisciplinary Pattern Recognition applications: A review
    Comput. Sci. Rev. (IF 7.707) Pub Date : 2020-06-08
    Marina Paolanti; Emanuele Frontoni

    Pattern recognition (PR) is the study of how machines can examine the environment, learn to distinguish patterns of interest from their background, and make reliable and feasible decisions regarding the categories of the patterns. However, even after almost 70 years of research, the design of an application based on pattern recognizer remains an ambiguous goal. Moreover, currently, there are huge volumes

    A power-efficient K-means clustering algorithm for Wireless Sensor Networks (WSN) is proposed. This algorithm aims to manage the consumption of energy by WS nodes and enhance the running time for WSN given space constraints. WS node cluster formation is structured as a sample space partition in k-means for the reason that the radio channel is unstable and the distribution of the nodes is coarse. After

    Community detection is a fundamental problem in social network analysis consisting, roughly speaking, in unsupervised dividing social actors (modeled as nodes in a social graph) with certain social connections (modeled as edges in the social graph) into densely knitted and highly related groups with each group well separated from the others. Classical approaches for community detection usually deal

  • Development of improved whale optimization-based FCM clustering for image watermarking
    Comput. Sci. Rev. (IF 7.707) Pub Date : 2020-07-18
    Kavitha Soppari; N. Subhash Chandra

    With the growing interest in copyright protection of multimedia, digital watermarking has been introduced and widely researched. The digital image watermarking approaches are generally adopted in the spatial or transform domain. Most of the transform-domain watermarking approaches are based on Discrete Cosine Transforms (DCT) and robust to JPEG lossy compression. Few contributions have been done using
