AlphaGo Zero: An overview of the algorithm

Jessica YungArtificial Intelligence, HighlightsLeave a Comment

In this post I go through the algorithms presented in the groundbreaking AlphaGo Zero paper using pseudocode. The objective is to provide a high-level idea of what the model does. Why AlphaGo Zero matters Last week, Google DeepMind published their final iteration of AlphaGo, AlphaGo Zero. To say its performance is remarkable is an understatement. AlphaGo Zero made two breakthroughs: … Read More

Bugger! Detecting Lane Lines

Jessica YungArtificial Intelligence, Highlights, Self-Driving Car ND3 Comments

This week I’ve been working on the first project of Udacity’s Self Driving Car Engineer Nanodegree – annotating lane lines in images and videos recorded from a front-facing camera mounted on the front of a car. There are plenty of blog posts floating around explaining the concepts (here’s my project code with a walkthrough of the process of annotating images), … Read More

Today we’re going to look at your Facebook homepage’s source code. This is interesting because it gives you an idea of the data Facebook is using every time you load your Newsfeed and accompanying ticker and chat windows, what exactly this data is, and how this data is stored and formatted. Here’s an example: (Scroll down for step-by-step instructions on … Read More
