In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Here we have given a matrix which contains set of elements and as per the problem statement we have to find out the sum of all the elements present inside the matrix. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given matrix =21 22 23 24 25 26 27 28 29 Sum ... Read More

Introduction Non-Negative Matrix Factorization (NMF) is a supervised algorithm used to represent data into lower dimensions which reduces the number of features while preserving enough basic information to construct the original matrix from the reduced feature space. In this article, we will be going explore more about NMF and how it can be useful. Non-Negative Matrix Factorization NMF is used to reduce the dimensions of the input matrix or corpus. It uses factor analysis which gives less importance to less relevant words. The decomposition of the original matrix(which is a non-negative matrix) thus creates a product of two non-negative coefficients ... Read More

The backbone of any project lies with requirements. The requirements identified, collected and documented at the initial stages, are generally designed, coded, tested, and takes the shapes of a product or an application to be used by the customers later. Those requirements are referred at any point of time by the team and other stakeholders to check whether the current project requirements are being met. And tracking back those bulk of requirements at the later stage of the project by manually examining the relationship between them is a cumbersome affair.Business Scenario – Case StudiesLet’s discuss a scenario, Mr. A is ...
