Such analysis can provide significant insights and decision support for businesses. Multiple research effort was conducted for market analysis including the Recency, Frequency and Monetary analysis (RFM) in addition to many variations including RFD, RFE, RFM-I and RFMTC. In this research a methodology is proposed to utilize the intermediate vector representation of the introduced RFMx for machine learning toward high precision automatic customer segmentation. In this methodology there’s no need to calculate the actual final RFMx score. The RFMx technique introduces a multimonetary model where each monetary value is assigned different weight to suite the business targets of business owners. The proposed model allowed for finely tuned market analyses on product type or service type level. The results showed significant clustering results that lead to automatic customer segmentation without the need to calculate the final RFMx score.","PeriodicalId":137729,"journal":{"name":"IJCI.

It is based on storing data in a decentralized distributed database with an encrypted way. Permission blockchains are the most of interest to companies, organizations, and other agencies to maintain their internal processes because of their trust, high privacy and control. Nowadays we are living in digital transformation age that everything should be maintained and operated by a system to ease our daily tasks. Electronic payment systems are one of many shapes for digital transformation, and they have many challenges in sending or receiving transactions as time latency, scalability, performance, and throughput rate also there is a need to maintain any failure through the payment process till it is completed. Tracing failed transactions may take more time and effort to discover what is the root cause of failure and which component has affected it. Therefore, the proposed framework is suggested using private blockchain to overcome the time delay of tracking failures and improve performance and throughput. Our results gained from the proposed framework enables us from tracing the failed transactions with little consumed time which provides more performance and efficiency.

It is mainly intended for education purposes, not for mere entertainment. Gamification can provide many benefits like creating a stimulating environment for learning and engagement with content in an unconventional way. These benefits are vital for the education of children with special needs because they suffer from constant distraction and loss of motivation. Therefore, we introduce a serious game prototype for children with special needs. The main purpose of this serious game is to assess total reading and understanding the impact of augmented reality as a learning methodology. This game is a complementary approach to motivate students after using an AR learning environment. This assessment game was designed according to the systemic gamification principles and contains the elements of game formula like points, time, and player profile. It will be used to assess children after learning sessions using AR and flashcards. The card assessment game is an unconventional way to evaluate children. Each child is different from her/his peers in the academic level, so the number of words is chosen at the beginning of the game based on what the child has learned in the training sessions. The child profile result confirmed that the game can be used in assessment. Moreover, parents and specialists confirmed that children enjoyed the assessment session, and the game is not limited to test only, as some children play it for language development.

Many of the previous mesh-based generative approaches work on natural shapes such as human faces and bodies and little work targets man-made objects. This work proposes a generative probabilistic framework for 3D man-made mesh shapes. Specifically, it proposes a Variational Autoencoder that works directly on mesh vertices and encodes meshes into a probabilistic, smooth, and traversable latent space that can be sampled after training and decoded to generate novel and plausible shapes. Extensive experiments show the representational power of the proposed framework and the underlying latent space. Operations such as random sample generation, linear interpolation, and shape arithmetic can be performed using the proposed method and produce plausible results. An additional advantage of the proposed framework is that it learns to produce a disentangled shape representation which gives finer control over the generated mesh and allows generating shapes with specific qualities without losing the reconstruction power of the autoencoder.","PeriodicalId":137729,"journal":{"name":"IJCI.

Dynamic port knocking which varies in each session, faces many challenges which are knocking sequence synchronization between client and server, handling high load of normal requests, out of order knocks, lost knocks, knocking through NAT, and knocking attacks. In this paper, a proposed dynamic port knocking approach is provided. The proposed approach, with the help of intermediate IPS, enables client and target server to generate a unique dynamic knocking sequence based on a secured random seed. This process is executed only at first communication session. Next, client begins to authenticate himself by knocking the target service with different ports and different number of knocks each time a session is initiated. Client-Server knocking synchronization, lost knocks, and out of order knocks are considered for issuing a correct knocking. The proposed approach provides immunity against several network attacks such as DoS attack, replay attack, and brute forcing attack. Extensive simulation shows that the proposed work overcome other compared approaches in terms of response time, memory utilization, CPU utilization, and the number of provided features.","PeriodicalId":137729,"journal":{"name":"IJCI.

Thus, it seems important to study factors and relations between the occurrence of different crimes to avoid more upcoming crimes. Crime prediction is a method of trying to study the causes and motives of crime and predict the times and places of its occurrence to reduce the commission of crimes that are expected to occur in the future. Data mining is an important way to facilitate the solution of future crime problems by investigating hidden crime patterns and historical crime data. Therefore, this study aims to analyze and discuss the various factors affecting the commission of crimes and the methods that are applied to predict future crimes and analyze their results. In this study, the model of crime prediction is proposed which is based on some classification algorithms such as (NB, KNN, Decision Tree, random forest, Linear Regression, Logistic Regression, SVM), these classification algorithms are applied to four real data sets (Chicago dataset, Los Angeles dataset, Egypt dataset, United States dataset), Egypt data set was extracted primarily from the online website (Zabatak.com) and comparing between their scores. The experimental results showed that the Random Forest classifier achieves a high score on four data sets compared with other classifiers. Random Forest achieves %88 on the Los Angeles dataset, %92 on the Egypt dataset, %97 on the Chicago dataset, and 81.7% on the United States dataset.
