This is an AI-based Chatbot, mainly based on machine learning algorithms and Bengali Natural Language Processing (BNLP). The machine gets embedded with this knowledge to identify the desired sentences and making a decision within itself, as a response to answer questions. There are many English Chatbot’s which used in education, web query, banking sector & various sectors. In this research, we have propounded a complete data-driven retrieval based closed domain Chatbot which is easily colloquy in the Bengali language with the users. We’ve created the train function adapter to train the Doly by encoding (encoding="utf8") our corpus from bot data. An input adapter has been created to take input and for output, an output adapter has been created to generate automated responses to a user’s input. We have also used a machine learning algorithm like search algorithm for finding an appropriate list of matching results from the corpus and use Naïve Bayesian algorithm to generate the right answer from data. The main aim of this Chatbot based system is to bridge the gap between the knowledge sources by providing instant replies to the questions and queries that have to ask in the Bengali language.

In this study, we have compared and applied the Autoregressive Moving Average (ARMA) model and the Vector Autoregressive (VAR) model to predict the annual inflation rate using data from January 2002 to December 2020. Various methods are employed to determine the optimal model specifications, followed by the generation of forecasts within a rolling estimation window. The results consistently indicate that the ARMA (2, 0) model outperforms other specifications in forecasting Polish inflation. These findings suggest that the inflation rate is expected to continue its downward trend in the coming years. Consequently, this study offers valuable insights for guiding future actions and policymaking in response to prospective inflation scenarios.

This technique has been applied to focus on how selling prices, the volume of sales, total costs such as variable cost and fixed costs as well as the mix of product sold affects profit. This research study aimed to determine the profitability position of several dairy farms in Bangladesh based on their cost-volume of the production. The study is conducted on two dairy farms named as Subarna Agro-Based Initiative and Nusrat Agro & Dairy Farm in Noakhali district. To obtain the objectives, ten years of financial data are taken from the period of 2009-10 to 2018-19 in the form of primary data. Utilizing these data profit volume ratio (P/V ratio), break-even point (BEP) and margin of safety are calculated for ten years. From the analysis, a P/V ratio from 2009-10 to 2018-19 is gradually raised and also break-even point demonstrates an optimal level considering the level of sales volume in ten years. Besides, the margin of safety helps us to know the risk level of a business. As-a-results, this article will lead to making how much cost to be spent to produce the required number of volumes of products to achieve the desired profit goal.

We can do binary operations like adding or multiplying two elements and also binary operations like taking the square root of an element (in this case the result is not always in the set). In this paper , we aim to find the operations and actions of Lie groups on manifolds. These actions can be applied to the matrix group and Bi-invariant forms of Lie groups and to generalize the eigenvalues and eigenfunctions of differential operators on n . A Lie group is a group as well as differentiable manifold, with the property that the group operations are compatible with the smooth structure on which group manipulations, product and inverse, are distinct. It plays an extremely important role in the theory of fiber bundles and also finds vast applications in physics. It represents the best-developed theory of continuous symmetry of mathematical objects and structures, which makes them indispensable tools for many parts of contemporary mathematics, as well as for modern theoretical physics. Here we did work flat out to represent the mathematical aspects of Lie groups on manifolds.

Friedmann equation is the standard model in cosmology. The solutions of the Friedmann equations explain the flat, open and close universe. In this paper, we have attempted to present the Friedmann equation mathematically. We also demonstrated the process ofhow to solve our proposed equation easily.

The three proposed methods are quite workable and practically well suitable for solving integration problems. Through the MATLAB program, our numerical solutions are determined as well as compared with the exact values to verify the higher accuracy of the proposed methods. Some numerical examples have been utilized to give the accuracy rate and simple implementation of our methods. In this study, we have compared the performance of our solutions and the computational attempt of our proposed methods. Moreover, we explore and calculate the errors of the three proposed methods for the sake of showing our approximate solution's superiority. Then, among these three methods, we analyzed the approximate errors to prove which method shows more appropriate results. We also demonstrated the approximate results and observed errors to give clear idea graphically. Therefore, from the analysis, we can point out that only the minimum error is in Simpson's 1/3 method which will beneficial for the readers to understand the effectiveness in solving the several numerical integration problems.

It is a statistical technique and is used as prediction with the curve fitting in machine learning, data science, economics etc. Linear and Polynomial regression is widely used to fit a curve and forecasting result. In this exploration, we propose two new linear and non-linear regression techniques using the strategy of interpolation-extrapolation and bisection of numerical analysis. However, interpolation and extrapolation cannot be applied in regression because of over fitting curve. In our paper, we have developed a technique to reduce the curve fitting that will enable the interpolation's and extrapolation's scheme to use in regression. Another procedure is to find out an equation of curve fitting with an optimal way using the Bisection Method. We also demonstrate the graphical presentations and comparison through all the occurring iterations.

It provides basically a concept of estimating unknown data with the aid of relating acquainted data. The main goal of this research is to constitute a central difference interpolation method which is derived from the combination of Gauss's third formula, Gauss's Backward formula and Gauss's forward formula. We have also demonstrated the graphical presentations as well as comparison through all the existing interpolation formulas with our propound method of central difference interpolation. By the comparison and graphical presentation, the new method gives the best result with the lowest error from another existing interpolation formula.

In this study, the four iterative methods are examined and emphasized to solve the nonlinear equations. From this method explained, the rate of convergence is demonstrated among the 1st degree based iterative methods. After that, the graphical development is established here with the help of the four iterative methods and these results are tested with various functions. An example of the algebraic equation is taken to exhibit the comparison of the approximate error among the methods. Moreover, two examples of the algebraic and transcendental equation are applied to verify the best method, as well as the level of errors, are shown graphically.
