Abstract: In recent years, data science has emerged as one of the most significant variables in both the realm of research and the realm of business potential. The existence of missing values is typically observed in real-world datasets, which might present a challenge. There are a variety of methods that can be used to deal with missing values. Imputation methods that are most commonly used to fill in missing data include the mean imputation, the median imputation, and the KNN imputation. The most significant drawback of the mean and mode methods is that, if there are a significant number of missing values, all of those values will be imputed with the same value. This will result in a change to the shape of the distribution, and the variance will be reduced when compared to its value before and after imputation. The more values that are absent, the greater the shrinking that will occur within the variance. In order to address this shortcoming of existing imputations, we have developed a brand-new imputation method. Multiple clustering's serve as the basis for multiple mean calculations (MMMC). When there are missing values in a dataset variable, MMMC imputation will substitute those values with several separate means rather than a single mean. The means obtained from the use of multiple clustering with the other variables contained in the dataset. The findings demonstrate that MMMC is superior to the other imputation strategies in a number of respects.

Abstract: Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative, conceptual idea, or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art. Music, theatre, film, dance, and other performing arts, as well as literature and other media such as interactive media, are included in a broader definition of art. The mishap faced by these artists led to the development of this work. This research work is centered on solving the problems faced by local artist having no means of displaying their art works to a wide audience, difficulty in exhibiting their works due to cost intensive and also lack of support and patronage by the government or other organizational bodies thereby hiding the rich culture and heritage of the nation. The methodology used in the development of the new system is the waterfall methodology. The system was created using the waterfall methodology, the language used was React.js and Node.js. with MongoDB. The result shows that Nigerian artists are availed with an exhibition infrastructure that is out of their reach, thereby enabling tem reach out to a wider audience.
