During last week’s blog post, we had a look at artificial neural networks. These were trained using data where a developer would know the input and correct output. Unlike them the algorithms we are looking today require no supervised learning.

First, we will be taking a look at Self-Organised Maps (SOM). It use...

Case based reasoning (CBR) is a a new method which might looks quite similar to previous rule based examples we have seen previously but has a few key differences.

CBR takes past experiences and categorises them as cases and uses them to solve future problems. The scope of these cases varies from implementation...

Genetic algorithms have long been a favourite subject of mine as there’s something about computing that is inspired by biology that is quite fascinating, almost mystical. After researching the subject and understanding the procedures behind what makes the algorithm work I can see how the implementation is quite...

This week I will be discussing reinforcement learning and Predictive Learning. This marks the departure of discussing non-learning learning algorithm and delving into the world of machine learning. There are three types of machine learning, Supervised, Unsupervised and Reinforcement. We will be looking at two o...

On to fuzzy logic, which is by far the AI technique with the cutest name. It was first formally developed by Dr. Lotfi Zadeh in 1965 and has since then been used in a variety of implementations and projects.

The simple explanation is that while non-fuzzy (called crisp or bivalued logic) values are Binary/Boolean...

Finite State Machines have been called the cornerstone of game-AI by many and for good reason. They offer an easy way to take a relatively complex target behaviour and emulate using states and transitions with great results. A simple example follows which demonstrates some basic behaviour that could be found in...

This week I’ll be looking at things from a different perspective. Instead of how other technologies can enhance game development I’ll be writing about how games can be a boon in others. There are many examples of this ranging from usage in film making to raising awareness for causes but as this is primarily an...

This begins my weekly blog posting on AI. The reason I am creating is because it is a requirement of my AI module. However, as my dissertation topic is quite close to this (using traditional AI methods such as neural networks, to create a crowd simulation and compare it to existing implementations) these blogs...
