The following problem is based on a problem in section 4 of the book “Model Building in Mathematical Programming”. I’ve modified some aspects of it but it’s similar in nature. …

I haven’t written anything on here since June 2020. I had originally planned to write some more about linear algebra and I’m not sure what happened. In college I briefly did some research on using linear programming to help reduce noise in signals. At that point I don’t think I…

Note : Everything written here is completely fictional and should only be viewed as both absurd and stupid. When Megacorp announced layoffs this week it didn’t come as a surprise for many after layoffs at many other companies however it did come as a surprise for engineering director Todd Smith…

Table Of Contents Introduction Norms SVD Introduction I was originally planning on writing a piece or a few short pieces on non-standard matrix decompositions and or new methods in matrix decompositions. Instead, I’ve decided to write an overview of numerical linear algebra so I can simply refer back to it. …

I’ve decided to make this type of story more frequent. I’m currently considering doing it every week. The subject of this story is about the math in the movie, ‘The Accountant’. There are several movies named, ‘The Accountant’, so to clarify I mean the 2016 action-thriller with Ben Affleck. …

The following was originally going to be about non-standard matrix decompositions, however it is going to take some more time than I expected to format it. Instead I was inspired to write about a piece of math I saw on a TV show. …

The following is an ongoing exercise to look at how to pre-aggregate data to quickly summarize it. I was previously using a database I generated that looks like this. The goal of this originally was to find a quick way of summarizing sales data for the purchases and the associated…
