In this second mini-tutorial I demonstrate using tensorflow to train a model to classify chess pieces from images.

We build and train a single layer neural network that takes in 32x32 grayscale images of chess squares and predict one of 12 chess pieces or an empty square. This combined with the previous post using computer vision to find tiles in a screenshot allows us to predict the layout of a chessboard from a screenshot.
Let's train a tensorflow neural network to tell what piece is on a chess square. In the previous post discussed how to parse input images which contained a chessboard into 32x32 grayscale chess squares. Let's look again at ou...

This post presents WaveNet, a deep generative model of raw audio waveforms. We show that WaveNets are able to generate speech which mimics any human voice and which sounds more natural than the best existing Text-to-Speech systems, reducing the gap with human performance by over 50%. We also demonstrate that the same network can be used to synthesize other audio signals such as music, and present some striking samples of automatically generate...

A friend of mine was having their quarter-life crisis, which apparently happens around the age of 25, so unfortunately I've missed mine already. This got me thinking about all the life crises that I've already missed and have coming up. I wanted to make a script that given my birthday would let ...

Well, many people might say that life crises can be irrational and sometimes even complex.

This post will discuss the ideation and building of SchmeckleBot. So, before I wrote the Tensorflow chessbot, I wanted to learn the basics of building Reddit bots, and decided to choose something that was both fun and solved ...

Amateur hour: I am learning to use a camera + telescope for astro photography,
and generated this image of Jupiter tonight used Registax with ~500 frames from a 30fps video captured using a Canon EOS 5d Mark III mounted to a Orion SpaceProbe 3 (76mm newtonian reflector telescope) with a 2x barlow lens.

In Registax I used a 50% drizzle to upsample, and wavelets to pull out the surface features, finally I color-balanced to remove the blue shift and come closer to true color.

Location is in downtown SF, high light pollution, today was a particularly clear night.

I decided to port my python morse code script over into a live demo web page (this is because live demos are infinitely easier with HTML5/javascript web pages which are client-side, instead of web server based solutions that would cost me compute resources to run/maintain).

So I'd written SchmeckleBot, a simple bot that converts currency from schmeckles to USD. But I decided to go even simpler, still in the theme of Rick and Morty (if you loved Futurama watch this!). A quote by Rick Sanchez (one...

Faint smell of urine in carpet of our room, missing utensils in room that took over 30 minutes to get, cost did not match the quality of the experience. good location and historic, but seems to have lost a lot of its luster
