Exact Inference Using Graphical Models

by Kiran R Karkera | June 2014 | Open Source

In this article by Kiran R Karkera, the author of Building Probabilistic Graphical Models with Python, we shall employ over fully specified graphical models to various inference engines to obtain answers to the questions.

Before we start on the inference trail, we shall learn about the complexity of the inference problem. Using different types of inference is appropriate in certain contexts, and we will learn which type is applicable where, and then experiment with both approaches.

Introducing variables

by John Bura | June 2014 | Games

Computer programming is based on mathematical principles. After all, the first computer was made to actually calculate equations, and it was only later that applications (as we know them) were developed. You have probably heard of variables in science and math classes. In computers, these variables are necessary to make applications and they are very important in games. Even a small indie game might have hundreds of variables. In this article by John Bura, author of Construct 2 Game Development by Example, we will look at what a variable is, why it is needed, and the different types of variables.

Variables are places where you can store small amounts of data. This data can be a name, a number, a date, a game object, or it can even store true or false information. Variables are essential to games because they can store items such as the following:

  • Score

  • Player name

  • Game objects

  • Mouse position

  • Keyboard input

Using the Playlist

by Shaun Friedman | June 2014 | Cookbooks

In this article by Shaun Freidman, author of the book FL Studio Cookbook, you can learn to arrange the many pieces and parts of your production by pasting patterns in FL Studio. You may also paint automation curves and record external audio in the playlist. The playlist is where you can specify which patterns are played (or not played) at which point in time. You can actually make a full-length song with one pattern by using the Piano roll and by continually adding more beats and bars with data. Thus, beats per bars is the area where you can distinguish between an intro, verse, chorus, bridge, outro, or any type of section of your song. It is all up to the individual artist using FL Studio to decide their particular musical arrangement. This is shown in the first recipe Using patterns to build a song.

In this article, we will cover the following topics:

  • Using patterns to build a song
  • Comparing patterns and audio
  • Using markers and snap
  • Viewing the playlist
