At the end of last year I was losing faith in my ability to study Data Science. Even though I had had a good first contact week, the material was incredibly difficult for me to understand. Following that, I wanted to work hard on my maths, but really had to start at a much lower point Read More

## Getting Up To Speed For Data Science: Maths

As I mentioned in previous posts, I’ve just finished my second contact week with the Uni for my apprenticeship and I am re-motivated to learn. The maths is the thing that has me the most stumped, so I’m going to take charge and stop hoping that the material I’m struggling with will suddenly make sense. Luckily, Read More

## Data Science Contact Week 2: Finished!

Today marks the end of my second contact week for my Data Science apprenticeship. My main takeaway is the same as last time, I should not be so worried about being behind, if I just put in the hours, I’ll be fine. After this week, I can even envision myself getting ahead as we now have Read More

## I Underestimated Data Science

I didn’t realise I was going to have to learn Linear Algebra and Calculus for this degree. It was silly of me really to so far underestimate what I would need to learn. From what I had read online, python or r can do all the work for you, you just need to learn the language Read More

## Learning Maths Can Be Better

When I was in school, maths was boring. We had textbooks with formulas and rules and the teachers would just walk through the exercises step by step. The closest we got to being engaged was when a teacher asked us to answer questions. No wonder we switched off. To me, the two biggest crimes in teaching Read More

## Data Science Contact Week 1 Day 2

Yesterday was my first day on the proper hands-on learning with programming a bit of interdisciplinary stuff. This morning was about analysis and optimisation and it was more about demonstrating to us what the point of all this maths is. Basically if you know the good maths, you can massively optimise your code and functions. Otherwise Read More

## Linear Algebra For Dummies

It’s interesting how different things with the same names can be. Linear Algebra in maths is scary and complicated. I’ve looked up so many courses, but even the “beginner” ones are intimidating. So when you start looking into Data Science and Machine Learning, spotting Linear Algebra lurking in the course content can cause worry. But it Read More

## Linear Algebra With R

Another Linear Algebra post! And why not, I’ve been playing with it more and more lately. I haven’t become super advanced in using it, I can’t tell you how it works just yet. What I can tell you is that learning R on Datacamp will give you some great basics in Linear Algebra. In fact, it Read More

## Linear Algebra And Excel Spreadsheets

Although I am just beginning with Linear Algebra, one thing occurred to me about matrices and vectors. I worried that in my ignorance, I was simply misunderstanding, but maybe not. I stumbled across the following quote and my little thought made sense: Linear algebra gives you mini-spreadsheets for your math equations https://betterexplained.com/articles/linear-algebra-guide/ Now THAT is something Read More

## Linear Algebra for Data Science

So here’s a big scary mathematical idea; Linear Algebra. It’s something my wife has studied towards her physics degree, so I know it’s complicated. There are all these funny words associated with it too. And knowing all that, I was concerned that it’s a part of Data Science. So yesterday I decided to do a little Read More
