microgpt

.post-header h1 { font-size: 35px; } .post pre, .post code { background-color: #fcfcfc; font-size: 13px; /* make code smaller for this post... */ } This is a brief guide to my new art project microgpt, a single file of 200 lines of pure Python with no dependen…

Deep Neural Nets: 33 years ago and 33 years from now

.post-header h1 { font-size: 35px; } .post pre, .post code { background-color: #fcfcfc; font-size: 13px; /* make code smaller for this post... */ } The Yann LeCun et al. (1989) paper Backpropagation Applied to Handwritten Zip Code Recognition is I believe of s…

A from-scratch tour of Bitcoin in Python

.wrap { max-width: 900px; } p { font-family: sans-serif; font-size: 15px; font-weight: 300; overflow-wrap: break-word; /* allow wrapping of very very long strings, like txids */ } .post pre, .post code { background-color: #fafafa; font-size: 13px; /* make code…

Short Story on AI: Forward Pass

p { text-align: justify; } .post pre, .post code { border: none; background-color: #eee; } The inspiration for this short story came to me while reading Kevin Lacker’s Giving GPT-3 a Turing Test. It is probably worth it (though not required) to skim this post…

Biohacking Lite

Throughout my life I never paid too much attention to health, exercise, diet or nutrition. I knew that you’re supposed to get some exercise and eat vegetables or something, but it stopped at that (“mom said”-) level of abstraction. I also knew that I can proba…

A Recipe for Training Neural Networks

Some few weeks ago I posted a tweet on “the most common neural net mistakes”, listing a few common gotchas related to training neural nets. The tweet got quite a bit more engagement than I anticipated (including a webinar :)). Clearly, a lot of people have per…

(started posting on Medium instead)

The current state of this blog (with the last post 2 years ago) makes it look like I’ve disappeared. I’ve certainly become less active on blogs since I’ve joined Tesla, but whenever I do get a chance to post something I have recently been defaulting to doing i…

A Survival Guide to a PhD

This guide is patterned after my “Doing well in your courses”, a post I wrote a long time ago on some of the tips/tricks I’ve developed during my undergrad. I’ve received nice comments about that guide, so in the same spirit, now that my PhD has come to an end…

Deep Reinforcement Learning: Pong from Pixels

--> This is a long overdue blog post on Reinforcement Learning (RL). RL is hot! You may have noticed that computers can now automatically learn to play ATARI games (from raw game pixels!), they are beating world champions at Go, simulated quadrupeds are learni…

Short Story on AI: A Cognitive Discontinuity.

p { text-align: justify; } The idea of writing a collection of short stories has been on my mind for a while. This post is my first ever half-serious attempt at a story, and what better way to kick things off than with a story on AI and what that might look li…
