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 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.

Check out my mini-tutorial on building machine learning model for predicting chessboard layouts from online chessboard screenshots.
I've been wanting to learn how to use TensorFlow, an open-source library that google recently released for machine learning and other applications. The introductory tutorials are great, teaching how to classify written number...

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...

X-plore: An Amazing Time-Lapse Journey

Dr. Lara and medical staff seem professional and straightforward, good experience for cleanings. Calling in to schedule appointments is difficult, getting put on hold and being completely ignored/forgotten every so often (as of June 2, 2016), which is annoying. Email communication similarly is not consistent. Hoping for communication quality to improve to normal standards so I can write an updated review.

Neighborhood gem, delicious tagine (fish or lamb both are fantastic), get the tea. The owners are extremely caring for their guests, and the vegetarian options are very good. I'll always bring my family here.

Fantastic indian food that is insanely low cost for the high quality. Felt like a family-owned restaurant, the masala tea is great (50c!), delicious naan and food options.
