Simon gets serious with Linear Regression (Machine Learning)

Simon has been working on a very complicated topic for the past couple of days: Linear Regression. In essence, it is the math behind machine learning.

Simon was watching Daniel Shiffman’s tutorials on Linear Regression that form session 3 of his Spring 2017 ITP “Intelligence and Learning” course (ITP stands for Interactive Telecommunications Program and is a graduate programme at NYU’s Tisch School of the Arts).

Daniel Shiffman’s current weekly live streams are also largely devoted to neural networks, so in a way, Simon has been preoccupied with related stuff for weeks now. This time around, however, he decided to make his own versions of Daniel Shiffman’s lectures (a whole Linear Regression playlist), has been busy with in-camera editing, and has written a resume of one of the Linear Regression tutorials (he actually sat there transcribing what Daniel said) in the form of an interactive webpage! This Linear Regression webpage is online at: https://simon-tiger.github.io/linear-regression/ and the Gragient Descent addendum Simon made later is at:  https://simon-tiger.github.io/linear-regression/gradient_descent/interactive/ and https://simon-tiger.github.io/linear-regression/gradient_descent/random/

And here come the videos from Simon’s Liner Regression playlist, the first one being an older video you may have already seen:

Here Simon shows his interactive Linear Regression webpage:

A lecture of Anscombe’s Quartet (something from statistics):

Then comes a lecture on Scatter Plot and Residual Plot, as well as combining Residual Plot with Anscombe’s Quartet, based upon video 3.3 of Intelligence and Learning. Simon made a mistake graphing he residual plot but corrected himself in an addendum (end of the video):

Polynomial Regression:

And finally, Linear Regression with Gradient Descent algorithm and how the learning works. Based upon Daniel Shiffman’s tutorial 3.4 on Intelligence and Learning:

Susy, a SASS framework

Simon has spent nearly the whole day trying to build a website following a Derek Banas tutorial on Susy, a SASS framework. He first built the website in Windows 10, then on a Mac. The problem he encountered with inserting an image in the Header caused many tears. In our case the image’s size was too big so we had to adjust its size manually in Photoshop and manually remove the white background. Simon always wants things to go exactly as shown in tutorials and was extremely frustrated.

Building a WordPress Website

Last week Simon decided he wanted to download WordPress (and MAMP) for his new laptop, too, and did it in something like one hour, maybe even less. Something that cost us both nearly three days the first time. He proceeded to building a “Learning WordPress” website and carried on for two days, until he got stuck. Says he will come back to this project at a later stage.

 

 

 

Here Simon tells me how he is going to turn his website into a blog using the REST API:
