Introduction to Tableau: Overview and Installation Tableau is a powerful and versatile data visualization tool that helps users quickly analyze, visualize, and share data insights. It allows users to connect to a wide range of data sources, such as Excel spreadsheets, SQL databases, and cloud-based applications, and transform raw data into interactive and engaging visualizations.…
In today’s world, data is everywhere, and its management has become a critical skill in various industries. Structured Query Language (SQL) is a programming language used to manage and manipulate data stored in relational databases. SQL is a vital tool in the data industry, and its demand is on the rise. In this article, we…
What is data science? Data science is an interdisciplinary field that involves extracting insights and knowledge from data using various statistical, computational, and machine learning techniques. It involves collecting, cleaning, processing, and analyzing large and complex datasets to identify patterns, trends, and correlations that can be used to make informed decisions. The goal of data…
Introduction to the Reduced Basis (RB) Method The Reduced Basis (RB) Method is a mathematical tool that has been gaining widespread popularity in recent years. It is a model order reduction approach that allows for the efficient yet reliable approximation of input-output relationships induced by parametrized partial differential equations. This method is particularly useful in…
Numerical linear algebra is a branch of mathematics that deals with the efficient computation of solutions to systems of linear equations and eigenvalue problems. One of the key tools in numerical linear algebra is the QR factorization, also known as QR decomposition. This powerful technique can be used to solve linear systems of equations, calculate…
Principal Component Analysis (PCA) is a widely used statistical method in the field of machine learning, data analysis and pattern recognition. It is a dimensionality reduction technique that helps to simplify complex data sets by transforming them into a new space with reduced dimensions, while preserving most of the important information. In this article, we…
Data Harnesing website has introduced TOPSIS Fuzzy software for the first time, which is available in both Excel and MATLAB environments. There is no restriction on the number of criteria and options that can be evaluated. The software comes with accompanying training files in the relevant package to make it easier for users to learn…
روش دنپ فازی (DEMATEL-based ANP) یا ANP فازی مبتنی بر دیمتل فازی، در واقع همان روش ANP فازی است که در آن ارتباطات درونی بر اساس روش دیمتل فازی مشخص شده اند. در روش فرایند تحلیل شبکه ای فازی کلاسیک، ارتباطات درونی بر اساس نظر کارشناسان تعیین میشدند. اما بعدها روش هایی ابداع شد که…
روش anp فازی (FANP) با مثال ساده کاملترین تکنیک تصمیم گیری چند معیاره بدون شک روش anp فازی است. این تکنیک توانایی در نظر گرفتن ارتباطات درونی بین عوامل را دارد و در عین حال عدم قطعیت در تصمیمات کارشناسان را نیز در نظر میگیرد. در روش فرایند تحلیل شبکه ای فازی امکان در نظر…
TOPSIS, or Technique for Order Preference by Similarity, is one of the MADM methods that can solve three-level problems. When we say a three-level problem, we mean a problem with a goal, criteria, and alternatives. You can see the structure of a three-level problem in this slide. We have four criteria and three alternatives. Here…
