AES Encryption 3: MixColumns 1 Dot Products
This video is on the MixColumns step in the inner loop of AES. Most of the topic for today is on how to manually multiply Galois fields, reduce them mod some polynomial, and add them together to compute a dot product. This is an important step in the construction of several look-up tables which form the basis of the mix columns step. We will eventually do the multiplication and reductions via a handful of lookup tables. This video does not present the entire MixColumns step but the rest is a little simpler once we look at dot products. This has been a tricky one to upload, I had it as one vid, but it was too long. So I split the matrix multiplication part to a separate vid. Hopefully, it's better that way.

Linear Algebra - Modulus & inner product
Mathematics for Machine Learning: Linear Algebra, Module 2 Vectors are objects that move around space To get certificate subscribe at: https://www.coursera.org/learn/linear-algebra-machine-learning/home/welcome ============================ Mathematics for Machine Learning: Linear Algebra: https://www.youtube.com/playlist?list=PL2jykFOD1AWazz20_QRfESiJ2rthDF9-Z ============================ Youtube channel: https://www.youtube.com/user/intrigano ============================ https://scsa.ge/en/online-courses/ https://www.facebook.com/cyberassociation/ About this course: In this course on Linear Algebra we look at what linear algebra is and how it relates to vectors and matrices. Then we look through what vectors and matrices are and how to work with them, including the knotty problem of eigenvalues and eigenvectors, and how to use these to solve problems. Finally we look at how to use these to do fun things with datasets - like how to rotate images of faces and how to extract eigenvectors to look at how the Pagerank algorithm works. Since we're aiming at data-driven applications, we'll be implementing some of these ideas in code, not just on pencil and paper. Towards the end of the course, you'll write code blocks and encounter Jupyter notebooks in Python, but don't worry, these will be quite short, focussed on the concepts, and will guide you through if you’ve not coded before. At the end of this course you will have an intuitive understanding of vectors and matrices that will help you bridge the gap into linear algebra problems, and how to apply these concepts to machine learning. Who is this class for: This course is for people who want to refresh their maths skills in linear algebra, particularly for the purposes of doing data science and machine learning, or learning about data science and machine learning. We look at vectors, matrices and how to apply these to solve linear systems of equations, and how to apply these to computational problems. ________________________________________ Created by: Imperial College London Module 2 Vectors are objects that move around space In this module, we look at operations we can do with vectors - finding the modulus (size), angle between vectors (dot or inner product) and projections of one vector onto another. We can then examine how the entries describing a vector will depend on what vectors we use to define the axes - the basis. That will then let us determine whether a proposed set of basis vectors are what's called 'linearly independent.' This will complete our examination of vectors, allowing us to move on to matrices in module 3 and then start to solve linear algebra problems. Less Learning Objectives • Calculate basic operations (dot product, modulus, negation) on vectors • Calculate a change of basis • Recall linear independence • Identify a linearly independent basis and relate this to the dimensionality of the space

Excel: How to Best Import External Data into Excel & Import data from the Web to Excel
Get the full course: http://www.xelplus.com/onlineAdvancedExcelCourse Excel has various tools that can help you easily clean up your raw data for further analysis. Apart from using formulas and formatting, there are two useful Excel features that let you easily clean up. One method is text to columns feature and the other to import external data. The Get External Data tool can be used to import and analyse data from other systems. This tool is also useful for importing data to run your dashboards or do further analysis using pivot tables, etc. Usually you can get data extracts from any system (e.g. “.dat” or “.csv” from Oracle, “.xml” files from SAP, etc.). These can be imported into Excel. Importing External Data also gives you control over the decimals and thousand separator, especially if you’re dealing with international companies. In the US, the decimal is dot and the comma is a thousand separator and in most European countries it’s the other way round, where the comma is a decimal and the dot a thousand separator. It’s always safest to Import it properly with the Excel Data Import wizard! After importing press Ctrl + T to create a table out of it. You can create a pivot table off this one, and when you do, even if you add more data to it, the pivot reflects the new data. Importing Data from the Web / Internet into Excel – creating web queries that refresh automatically: In Excel you can also import data directly from the web. You basically create a web query which you set to refresh automatically based on your preference. ➹ ➹ ➹ My Online Excel Courses ➹ ➹ ➹ Excel VBA & Macros ► http://bit.ly/LeilaVBA Excel Dashboards ► http://bit.ly/LeilaDashboards Excel Charts ► http://bit.ly/LeilaCharts Advanced Excel ► http://bit.ly/LeilaAdvancedExcel Excel Waterfall Charts ► http://bit.ly/LeilaWaterfall 🕮 Recommend Excel Resources 🕮 https://www.xelplus.com/resources/ ✉ Subscribe to my Newsletter ✉ Stay informed and get discounts when new courses come out: http://www.xelplus.com/

How to Use Icon Sets with Text Values in Excel
How to Use Icon Sets with Text Values in Excel For more Excel Conditional Number Formatting Tips and Tricks visit me at http://bradedgar.com In this video I run a little longer than my 60 second threshold so I've added the + to my icon as you can see in my image. That being said I tackle a few different things in this video. Custom Number Formatting Syntax Review: [positive numbers; negative numbers; zero value; text] Custom number formatting has sections for each type of number as displayed above. Let's have a look how I use this in this video. (1) I show you how you can take numbers and apply text values to them based on what the value is. For example, if the value is positive, I'll show complete, if the value is negative, I will show behind and if the value is zero, I'll show on target. You will get to go through each step that it takes to do this. Notice I built a legend showing you that a value of 1 will show as complete, a value of 0 will show as on target and a value of -1 will be displayed as a negative. (2) Once we've applied the Excel custom number formatting, we can now move forward with applying our icons sets. Icon sets in excel are a great feature for displaying how well something is performing. In this video, we use icon sets with text values and custom number formatting to display icon sets with texts. Because complete is assigned a value of 1 in our cells, on target a value of 0 and behind -1, we can use the numbers applied to the cells (even though they are being displayed as text) to apply icons. Green icon sets will be applied a value of 1, Yellow icon sets a value of 0 and negative 1 will display in red. This is an excellent way to monitor and display status' in a visual way so that's easy to tell at what stage you are in your projects. I'm sure you can think of a million other uses for it. Here are a few other links and resources for you: Excel Custom Number Formatting: How To Conditionally Format Text Fields With Icon Sets Using Number Formatting: http://bradedgar.com/excel-custom-number-formatting-conditionally-format-text-fields-icon-sets-using-number-formatting/ 5 Incredible Number Formatting Tricks That Will Impress Your Boss: http://bradedgar.com/5-incredible-number-formatting-tricks-will-impress-boss/ How to Use Icon Sets in Excel: http://www.excel-easy.com/examples/icon-sets.html Excel conditional formatting Icon Sets, Data Bars and Color Scales: https://www.ablebits.com/office-addins-blog/2014/06/05/excel-conditional-formatting-icon-sets-data-bars-color-scales/ The Ultimate Guide to Custom Number Formatting: http://jonvonderheyden.net/excel/a-comprehensive-guide-to-number-formats-in-excel/ -~-~~-~~~-~~-~- Checkout my newest video: "How to Use the Vlookup Formula in you Excel Dashboard" https://www.youtube.com/watch?v=MCBmPnaKf_g -~-~~-~~~-~~-~-

Linear Algebra 11y: The Transpose of a Triple Product
This course is on Lemma: http://lem.ma Lemma looking for developers: http://lem.ma/jobs Other than http://lem.ma, I recommend Strang http://bit.ly/StrangYT, Gelfand http://bit.ly/GelfandYT, and my short book of essays http://bit.ly/HALAYT Questions and comments below will be promptly addressed. Linear Algebra is one of the most important subjects in mathematics. It is a subject with boundless practical and conceptual applications. Linear Algebra is the fabric by which the worlds of geometry and algebra are united at the most profound level and through which these two mathematical worlds make each other far more powerful than they ever were individually. Virtually all subsequent subjects, including applied mathematics, physics, and all forms of engineering, are deeply rooted in Linear Algebra and cannot be understood without a thorough understanding of Linear Algebra. Linear Algebra provides the framework and the language for expressing the most fundamental relationships in virtually all subjects. This collection of videos is meant as a stand along self-contained course. There are no prerequisites. Our focus is on depth, understanding and applications. Our innovative approach emphasizes the geometric and algorithmic perspective and was designed to be fun and accessible for learners of all levels. Numerous exercises will be provided via the Lemma system (under development) We will cover the following topics: Vectors Linear combinations Decomposition Linear independence Null space Span Linear systems Gaussian elimination Matrix multiplication and matrix algebra The inverse of a matrix Elementary matrices LU decomposition LDU decomposition Linear transformations Determinants Cofactors Eigenvalues Eigenvectors Eigenvalue decomposition (also known as the spectral decomposition) Inner product (also known as the scalar product and dot product) Self-adjoint matrices Symmetric matrices Positive definite matrices Cholesky decomposition Gram-Schmidt orthogonalization QR decomposition Elements of numerical linear algebra I’m Pavel Grinfeld. I’m an applied mathematician. I study problems in differential geometry, particularly with moving surfaces.
