“…SVD has been successfully applied to signal processing (speaker verification systems) [19], image processing (noise filtering, watermarking) [20], image compression [21], and big data, e.g., in genomic signal processing (transforming genome-wide expression data and analysis of genome-scale data) [22,23]. PCA is also used in signal processing (diagnosing and predicting machine damage) [24,25], image processing (extracting image features) [26], and analysis (pattern recognition and image compression) [27].…”

(1) Background: Improving the management and effectiveness of employees’ learning processes within manufacturing companies has attracted a high level of attention in recent years, especially within the context of Industry 4.0. Convolutional Neural Networks with a Support Vector Machine (CNN-SVM) can be applied in this business field, in order to generate workplace procedures. To overcome the problem of usefully acquiring and sharing specialist knowledge, we use CNN-SVM to examine features from video material concerning each work activity for further comparison with the instruction picture’s features. (2) Methods: This paper uses literature studies and a selected workplace procedure: repairing a solid and using a fuel boiler as the benchmark dataset, which contains 20 s of training and a test video, in order to provide a reference model of features for a workplace procedure. In this model, the method used is also known as Convolutional Neural Networks with Support Vector Machine. This method effectively determines features for the further comparison and detection of objects. (3) Results: The innovative model for generating a workplace procedure, using CNN-SVM architecture, once built, can then be used to provide a learning process to the employees of manufacturing companies. The novelty of the proposed methodology is its architecture, which combines the acquisition of specialist knowledge and formalising and recording it in a useful form for new employees in the company. Moreover, three new algorithms were created: an algorithm to match features, an algorithm to detect each activity in the workplace procedure, and an algorithm to generate an activity scenario. (4) Conclusions: The efficiency of the proposed methodology can be demonstrated on a dataset comprising a collection of workplace procedures, such as the repair of the solid fuel boiler. We also highlighted the impracticality for managers of manufacturing companies to support learning processes in a company, resulting from a lack of resources to teach new employees.

A phishing email is legal-looking email which may be planned with trap the beneficiary under trusting that same as certifiable email, Furthermore Possibly uncovers delicate data or downloads pernicious injecting codes through clicking ahead pernicious joins held in the particular figure of the email. There would various provisions receptive to phishing ID number. However, Dissimilar to predicting spam there need aid exactly couple of focuses that ponder machine Taking in routines to anticipating phishing. In this paper an information set is used to arrange those phishing identification those display dataset employments choice tree to predicting phishing messages. We would be setting off should investigate consideration of extra variables of the data set, which might enhance the predictive correctness of classifiers. For example, analysing email headers need demonstrated will move forward the prediction ability What's more diminishing those misclassification rate about classifiers.

“…The general method of image representation is in matrix, made up of size m*n. where, m signifies the number of rows, which is the pixel height of the image and n is the number of columns which shows the pixel width of the image. Every element of the matrix gives the representation to each pixel that makes up the image [4].…”

“…The SVD is essentially factorizing the given matrix into multiple matrices. SVD factorizes the given matrix with m number of rows and n number of columns it into three matrices; which can be written as M=UΣVT where U and VT are orthogonal matrices of the order m*m and n*n respectively and Σ is a diagonal matrix of the order m*n. Diagonal matrix Σ consists of nonnegative real numbers which are called as singular values of M. The m columns of U and n columns of VT are known as the left and right singular vectors of M respectively [4] The steps involved in the SVD process are shown in figure 2.…”

Storing images consumes a lot of storage space due to the large number of bits used to represent them. These bits are comprised of pixels that make up the image. These heavy images are also very difficult to be transmitted over channels due to their great size. Compression involves the reduction of the amount of bits used in representing an image and consequently reducing the size of that image without losing any detail from the image. There are so many image compression techniques used to achieve this feat, but they have drawbacks such as lack of a model that can compress a satellite image, lack of adaptive reversible techniques for compression and inability to compress complex images such as satellite images. This work, proposed an hybrid Discrete Wavelet Transform, Discrete Cosine Transform and Singular Value Decomposition (DCT-DWT-SVD)based techniques for satellite image compression. The algorithms were combined to breakdown the images into blocks/matrices and assign certain values to them depending on the concentration of colour bits around the region. The areas with higher bits are reduced and compression is achieved. A hybrid methodology of Agile and Waterfall model was used in this approach. The model was implemented using MATLAB and satellite images gotten from a public repository. The Compression ratio was 0.9990 and 0.9941 for the two images compressed which shows high and efficient compression. The Mean Square Error (MSE) was 2.51 which is low. This study will be beneficial to remote sensor companies, Graphic designers and the research community.
