Daniel O'Connor

Here are my resume, my PhD thesis, and my Google Scholar page. You can also find me on LinkedIn and X.

I post on math.stackexchange under the username littleO.

YouTube videos

Here are my machine learning videos and my multivariable calculus videos.

Linear Algebra slides

Here are 300+ slides that I used when teaching linear algebra.

Multivariable calculus slides

Here are 250+ slides that I used when teaching vector calculus.

Intro to Deep Learning slides

These slides give a quick introduction to deep learning using PyTorch.
