The Imitation Game, Part IV

The Imitation Game, Part IV 

Sorry, I can't stop. There's just always more.

I might do 5 minutes of Linear Algebra here and there to perk me up throughout the day. To spike my interest and keep my attention. I need to carve out my little niche. 

I just love AI and I love AI learning.

I love AI so, so, so much.

Matrix Operations


"Like with vectors, there are fundamental operations we can perform on matrices that enable the linear transformations needed for algebra." 

"We can again multiply entire matrices by a scalar value, as well as add or subtract matrices with equal shapes."

"A new and important operation we can now perform is matrix multiplication. 

"Matrix multiplication works by computing the dot product between each row of the first matrix and each column of the second matrix."

"An important rule about matrix multiplication is that the shapes of the two matrices AB must be such that the number of columns in A is equal to the number of rows in B."

THAT MAKES SENSE.

MATRICES CAN ONLY BE MULTIPLIED IF THE NUMBER OF COLUMS IN A IS EQUAL TO THE NUMBER OF ROWS IN B.

WOW WOW WOW WOW WOW WOW WOW WOW

wow, wow, wow, wow, wow.


And then...




And so on...

THE PRODUCT OF A 2X3 MATRIX AND A 3X2 MATRIX ENDS UP BEING A 2X2 MATRIX

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as ...

Yosemite

Yosemite I'll never forget the first time I head the song Yosemite by Lana del Rey. I very nearly clicked away.  It was quite near the start of my Software Engineering journey, right near when I start learning the Front-End/Web Development. I was listening to Arcadia by LDR before, maybe twice, and then Blue Banisters came on. I nearly clicked away in the first 30 seconds but I forced myself to keep listening anyway.  I'll never forget how that song has made me feel. It became my song of 2022 even though I only discovered it in November. I can still listen to it every day and get that complete sense of wonder and of awe that I felt the first time that I heard it. That ending of the song is completely amazing, and it just completely just blows me away every time. "Withstanding all the time, changes, and seasons..." - LDR Concise Body Arrow Functions Why am I so bad at arrow functions? Whyyyyyyyyyyy?  Just kidding, I am beginning to get them. But why are they so hard? ...

Where To Hide A Star

Where To Hide A Star I haven’t read this book but I just saw this title of a forthcoming children’s book on the train and so I wanted to write a blog post based off of this as well. The last six months have been… rewarding and fulfilling. I have managed to make all of my dreams come true and to defy expectations,  Sometimes the best place to hide is in plain sight and if you reread all of my blogs over the last six months (all 200 of them) you would know exactly what I’m struggling at work and what was going on. And why. But I’ve managed to overcome most of my challenges. Neurodiversity. Being very new in the field relative to the expectations of the job. Being in a new workplace environment. All stuff which I can handle and I am doing just fine. Because I am amazing and fabulous and I can do anything. I am loving the job. I am thriving. I am loving just getting on with it. I love my work. I am having massive breakthroughs. On Thursday I had what felt like the biggest breakthrough ...
