Two-phase feature extraction with chi square-based feature selection approach for the classification of online product reviews

As Internet technology progresses, users are increasingly opting for online shopping. Users can now not only purchase items but also offer feedback on their satisfaction with them. In terms of enhancing product quality, these reviews are incredibly valuable to both the user and the vendor. It becomes challenging to manually process a large amount of review data that is increasing in volume, subjectivity, and heterogeneity. To address this issue, machine learning (ML) technologies have been used in real-world applications, although there are still many hurdles. In order to achieve a more accurate result, this research study has used a mix of many fundamental machine learning techniques. Two-phase feature Extraction is used with chi square-based feature selection (FS) to reduce the dimension of the data. Three Ensamble classifiers were utilised, which merged several basic classifiers to choose the best outcome. The suggested model is tested using a dataset of 74000 product reviews from two well-known e-commerce sites, Flipkart and Amazon. And the model produces the most accurate results, with a 98% accuracy rate.
PENGOLAHAN CITRA DIGITAL DAN LOGIKA FUZZY DALAM IDENTIFIKASI TINGKAT KEMATANGAN BUAH

This study aims to implement digital image processing and fuzzy logic in identifying the maturity level of red dragon fruit and describing the level of accuracy. The process carried out is to change the type of red dragon fruit image from the red green blue (RGB) type to the grayscale type. Furthermore, extraction is carried out using MATLAB to obtain information from the image. Information from the image is contrast, correlation, energy, homogeneity, mean, variance, entropy. There are 7 information used as fuzzy input. The input fuzzy model uses triangular and trapezoidal membership functions to construct fuzzy rules on 28 data, so there are 28 fuzzy rules. After the fuzzy rules are obtained, then the inference and defuzzification processes are carried out. The inference used is the mamdani method. The result of defuzzification is the value for the maturity level of red dragon fruit which is divided into four categories, namely raw, half-ripe, ripe, rotten. The fuzzy model that has been built will test the model by determining the level of accuracy and error of the model. With the results of 96.42% with an error of 3.57%.
Exploring Representation of Horn Clauses using GNNs (Extended Technical Report)

Learning program semantics from raw source code is challenging due to the complexity of real-world programming language syntax and due to the difficulty of reconstructing long-distance relational information implicitly represented in programs using identifiers. Addressing the first point, we consider Constrained Horn Clauses (CHCs) as a standard representation of program verification problems, providing a simple and programming language-independent syntax. For the second challenge, we explore graph representations of CHCs, and propose a new Relational Hypergraph Neural Network (R-HyGNN) architecture to learn program features. We introduce two different graph representations of CHCs. One is called constraint graph (CG), and emphasizes syntactic information of CHCs by translating the symbols and their relations in CHCs as typed nodes and binary edges, respectively, and constructing the constraints as abstract syntax trees. The second one is called control- and data-flow hypergraph (CDHG), and emphasizes semantic information of CHCs by representing the control and data flow through ternary hyperedges. We then propose a new GNN architecture, R-HyGNN, extending Relational Graph Convolutional Networks, to handle hypergraphs. To evaluate the ability of R-HyGNN to extract semantic information from programs, we use R-HyGNNs to train models on the two graph representations, and on five proxy tasks with increasing difficulty, using benchmarks from CHC-COMP 2021 as training data. The most difficult proxy task requires the model to predict the occurrence of clauses in counter-examples, which subsumes satisfiability of CHCs. CDHG achieves 90.59% accuracy in this task. Furthermore, R-HyGNN has perfect predictions on one of the graphs consisting of more than 290 clauses. Overall, our experiments indicate that R-HyGNN can capture intricate program features for guiding verification problems.
A Novel Model for Visual Content Based Image Retrieval using Transfer Learning

At present, the revolution brought by deep learning based technologies in the field of computer vision gaining momentum in the world of artificial intelligence. In particular, the best models for retrieving common images today are based on features generated by deep convolutional neural networks (DCNNs). However, this great success was expensive. A comprehensive amount of tagged data had to be collected, followed by model design and training. Meanwhile, a transfer-of learning approach has been developed that avoids this costly step by applying a sophisticated, pre-trained generic DCNN model to completely different data domains. With the use of transfer learning, it becomes possible to use deep CNN models for small datasets with better retrieval performance with respect to handcrafted feature based retrieval methods. In this paper a deep CNN based model has been proposed which uses concept of transfer learning and achieves good classification accuracy.

Poetics of the Opera Genre

The paper considers the poetics of opera as a factor in ensuring genre self-identification during over four centuries of opera history. It focuses on the root sources of opera related to the system of musical and theatrical genres. With the emergence of opera at the turn of the seventeenth century, its poetics was formed simultaneously in two versions: in the verbal texts and explanations and in the system of linguistic and expressive means of the works. The idea of the conditional existence of three different stories of opera is suggested. Each system is built depending on which components are the main focus when considering the historical material. There is opera as a “chanted drama”, opera as a genre of vocal-instrumental music, and finally, opera as one of the independent types of theatrical art. The three main elements of opera poetics and the functions of each of them are revealed on the example of the analysis of the sixth work in the history of the genre and the first truly classical example, the opera L’Orfeo byClaudio Monteverdi. If the opera characteristic vocal language and sung dialogues became a purely operatic innovation, two other elements of opera poetics used in this opera were actively developed throughout history: instrumental music, as well as choral and ensemble scenes. Thus, opera poetics is associated with constant flexible interaction of the laws of dramatic, musical, and theatrical arts.
Just playing: Valera and Natasha Cherkashin

The paper outlines the game preconditions of artistic creativity of the artist Valera Cherkashin (Valery T.Cherkashenko, was born 1948 in Liptsy village, Kharkiv region, USSR) during the 1960s–1980s, as well asthe first period of his collaboration with Natasha Cherkashin (Natalia S. Polyakova, born 1958 in Damascus, Syria). From the first half of the 1960s to the 1980s, V.Cherkashin organized a number of art events in Kharkiv, using elements of Soviet and Western mass culture. Cherkashin’s artworks blur the boundaries between traditional genres and styles in the visual arts. While experimenting with the art form, Cherkashins in addition to the language of art action have been using the language of photography, of cinema, painting, graphics and video. Artists continue to create art in different media. Currently, Cherkashin’s artworks are in the collections of the leading museums and corporate collections around the world. The aim of the research is to reveal the ontological, methodological and axiological bases of Cherkashin’s artistic creativity. During the analysis the playing preconditions in Cherkashins’ creativity. Feelings of tension and joy, as well as sense of otherness are inherent in all the artistic work of the Cherkashins. V.Cherkashin creates a new conceptual meaning—the image of the “other” in the early photographic series of 1965–1966 and the image of a social outcast who is between two worlds in 1972. During Cherkashin’s play, the seriousness is eliminated, it becomes funny. The funny side of Cherkashins’ artworks is rooted in harmless nonsense. Artists turn ideological and verbal codes and images into “funny nothing”. Joyful life-affirming laughter in the Cherkashins’ works is the second “actor,” along with the ‘new plasticity.’ Biographical, conceptual, descriptive-phenomenological methods of analysis, comparative studies and hermeneutics were used during the research.
Analysis of changes in the concept of doctoral studies. Approaches through the prism of policies promoted at european level

The article analyzes the aspects of doctoral treatment at European level. The doctorate becames part of the higher education (cycle III) in the early 2000s and has been an important element of the Bologna process and the development of the European Higher Education Area (EHEA). The announcements of the ministers responsible for higher education in European countries as a result of their regular meetings, provide various activities for the development of a common framework for doctoral studies at European leve as welll. At the same time, the processes of globalization and the development of knowledge-based economies pose a number of challenges to the process and purpose of doctoral studies, which are widely debated by researchers, experts and decision makers. International experience can be useful and needs to be taken into consideration in the process of reforming the doctoral studies in the Republic of Moldova, especially in the context of implementing actions to integrate national higher education in the EHEA.
A Study on the Impact of Bitcoin on the Indian Economy

Abstract: The silence of the RBI on the regulatory status of bitcoins may prove to be damaging. An industry has grown around bitcoins in India- traders, exchanges and merchants who accept payments in bitcoins. Bitcoins have already gained wide acceptance around the world- hence banning them would not be an option in India. Instead, this industry would need to be regulated. The sooner this is done, the better. A bitcoin is a virtual currency first introduced in the year 2008 by an anonymous group called Satoshi Nakamoto. It’s an open source peer-to-peer cryptographical system (direct connections without an intermediary) where transactions happen through a public ledger called blockchain, handling users’ data anonymously. Eight years since its introduction, bitcoin is today the most widely used and accepted digital currency.By categorically reiterating that cryptocurrencies could not be part of the ‘payment process’, India buries the economic possibilities of crypto as a currency. However, the positive focus on blockchain technology is redeeming the bitcoin
