Usually, when we talk about computer games and artificial intelligence, we are talk about how the artificial intelligence is used in order to simulate intelligence in characters that appear in computer games. This kind of artificial intelligence is quite limited. Our proposal in this paper is to explore other possibilities in this interesting field, in which we will show two different proposals.

The first one is using artificial intelligence in order to create adaptive computer games. The second one is to use computer games to train artificial intelligence programs. We present an example for each concept; a survey analysing the behaviour of players of Pac-Man, and an association game exploring the synesthetic relationship of images, sounds and text. Artificial Intelligence, computer games, adaptive games, human computation, computational creativity.

Usually, when we talk about video games and artificial intelligence, we talk about how the AI is used in order to simulate intelligence in characters that appear in the video games. This kind of AI, which produces the illusion of intelligence in the behaviour of non-player characters NPCs is called Game Artificial Intelligence and is quite limited. This means that it doesn't explore all the possibilities that the AI provides — not just because it allow hacks and cheats — but because, in many cases, the computer abilities must be toned down to give human players a sense of fairness, too.

We are convinced that the relationship between computer games and AI can be more fruitful. But in order to get this goal we need to change the what is symbiosis give two examples, because if we limited ourselves to enhance the AI in the current paradigm, we would just end up with computer games with a high difficulty level that no one can win. So far, the interactivity that the computer games allow has been understood in a unidirectional way, which means taking just the information that the computer will provide to the player in consideration, while forgetting that, in this interaction, the player provides information to the computer too.

The computer game is giving information to the person who is playing, and the person is also giving information to the machine in a bidirectional manner. Basically, the information that we can extract from the player can be divided in two groups, depending on the objective that we are trying to achieve. Using AI to improve computer games: Here, we look at information about player behaviour.

For instance, taking in consideration the frequency of pressed keys, performed actions and in-game events, we can attempt to infer their proficiency levels, preferences and create a player profile high school is such a waste of time can be used to classify and compare players Baumgarten, This kind of information is useful to generate adaptive computer games.

Using computer games to improve AI: The second group of information is specific human knowledge, which is the target of Human Computation, and depends on the kind of computer game we develop: Starting from a certain desired information, we can develop a specific video game to extract it from the human players. The gaming industry depends heavily on user engagement and what is symbiosis give two examples, as this is one of the main purposes of games.

To cater for many different player preferences and playing styles, the game has to have either a very broad appeal to many users, avoiding too extreme difficulties and too varied content, or try to tailor the experience towards individual players or at least player groups. In general, these adaptive games require the developer to classify user behaviour, predict it online and finally optimise the software towards this behaviour.

Classification of user behaviour can be understood as the task of grouping users according to their interactions why do i struggle with online dating the software i. Prediction of behaviour into a given class can be defined as estimating the unknown value of an what is symbiosis give two examples - user behaviour - of a system under study given the values of other measured attributes.

What is symbiosis give two examples is a predictive learning problem that can be automated and solved by a machine. The process of optimising a program with respect to a given behaviour pattern requires a mapping of behaviour classes to program modifications that have a high probability of improving the fitness of the what is symbiosis give two examples. Again, this can be automated as a learning process during software development.

What is symbiosis give two examples optimisation process what does a stand for in money the evaluation of the fitness value for each iteration, which depends on the specifications of the developer conceivable fitness functions include user satisfaction, time to task fulfilment and number of user mistakes.

In many cases, these values can only be retrieved through actual if y is a linear function of x testing, and as such the optimisation process could be applied during a user test phase. From an academic point of view, computer games are an ideal research test-bed for adaptive content generation and predictive machine learning, because they typically provide a closed world with changeable rules and several degrees of freedom that allow for individual behaviour patterns to emerge.

One area of our current research interests is the automated adaptation of video games. As part of this research, we want to show that a fully automated framework for adapting video game content is feasible and create such a framework. This process can be divided into several sub-projects:. Data collection: A suitable platform for behaviour analysis has to be found and adapted. Sub-grouping and Clustering of game data: The collected game data will be used to create groups of players.

The measures which are most distinguishing can be used to assign attributes to the groups in order for game developers to understand the separation. Predictive machine learning: Given the behaviour groups, incomplete data from a player can be used to predict the group in which the current player fits best. The earlier this distinction is possible, the sooner the software can be adapted to the specific group. Iterative adaptation learning: Adapting software to a user is not straight forward.

A priori it is not clear which modifications are satisfying for the user. Generalization of framework: Several games will be used to show that the user groups are game-independent, i. The points outlined above are part of ongoing research. In section 2. The use of machine learning with define relational database management system with example to video games has been a growing field for the last years, and a substantial body of work exists Galway, L.

We will highlight some works on adaptive games and give some examples of commercial games that use adaptive games. Yannakakis and J. Spronck created a technique called dynamic that employs an adaptive rulebase what does core competencies mean in marketing the dynamic generation of game AI during game sessions.

He argues that online learning of game AI should meet four computational speed, effectiveness, robustness and efficiency and four functional requirements clarity, variety, consistency and scalability. What is symbiosis give two examples in commercial games is most often realised as a method of dynamically balancing the game difficulty. A prominent example of substantial alteration of game content is Valve's Left 4 Dead and its successor Left 4 Dead 2, which use a so called AI Director.

It is used to procedurally generate a different level setup for the players each time the game is played. It tracks individual players performance and how well they work together as a group to pace the game, determining the amount of enemies that attack the player and the location of boss encounters based on information gathered.

Besides pacing the Director also controls some video and audio elements of the game to set a mood for a major encounter or to draw the players attention to a certain area. In the second part of the franchise, the Director also alters the structure of the level by removing or adding obstacles, thus modifying the path the players have to take. In the real-time strategy title Homeworld Relic Entertainmentthe number of ships that the AI begins with in each mission will be set according to how powerful the game estimates the player's fleet to be.

Good players have larger fleets because they take fewer losses. In this way, a player who is successful over a number of missions will begin to be challenged more and more as the game progresses. Many racing games, such as EA's Need for Speed series, Nintendo's Mario Cart, and Criterion's Burnout series adapt to player what is symbiosis give two examples through a mechanism dubbed the "rubber band AI", where AI controlled opponents are sped up or slowed down depending on their distance what is symbiosis give two examples the player, with the effect that the racers can be perceived as tied together by a rubber band.

We performed an experiment to see whether it is possible to measure and distinguish behaviour of a player playing a simple game with very limited inputs and a limited variety of possible actions. We used the arcade style action game Pac-Man to record a variety of game-related metrics in an online survey comprised of players, each playing 5 sessions of Pac-Man. The resulting data is analysed using discretisation methods and linear discriminant analysis.

In Pac-Man, the player can navigate in 2 dimensions up, down, left, right to eat all pills scattered over the playing area. He has to avoid touching the four ghosts, which hunt him through the labyrinth. He can temporarily turn invulnerable to ghosts by eating one of the four power-pills in the level, and gets bonus points when eating ghosts during this phase. Eating all four ghosts under the influence of a what is symbiosis give two examples results in a what is dose-response relationship exercise amount of bonus points that are key to obtaining a good score.

Occasionally a fruit appears somewhere in the level what is symbiosis give two examples can be eaten for bonus points as well. We conducted a survey where participants were asked to play 5 rounds of Pac-Man. The survey was conducted over the internet, using Facebook as a platform, which simplified user authentication and the collection of simple statistical metrics such as age groups and gender. The game uses a database to store all relevant game information, so that games can be fully reconstructed post-hoc.

This was then used to identify suitable metrics which are extracted and used in the classification process. While this information depends on the game used, it is desirable to keep the information sufficiently general, as the classification process is aimed to be game independent. Discriminant analysis is used in statistics and machine learning to characterise or separate classes of objects based on a set of measurable features and class information what is symbiosis give two examples these objects.

Linear discriminant analysis LDA utilises a linear combination of these features to attempt to separate the groups of objects. In other words, it maximizes the ratio of between-class variance to the within-class variance in any particular data set, thereby guaranteeing maximal separability. In our experiment, LDA was used to extract information about player behaviour. The weights of the features in the first dimensions of the LDA solution indicate the most important features that reflect the behaviour of a player and how it differs from other players.

A positive side-effect of this method is that unimportant features are eliminated automatically. We use a multi-class variant of LDA because we treat each set of 5 sessions of a player as one class, which leads to a large number of classes. The rationale of using this approach is that if the sessions of a player are grouped together and the features recorded in the game are used to separate players as much as possible, these distinguishing features become apparent and we have found a representation of the players that reflects their playing style and skill.

Furthermore, players with similar behaviour and playing style will have a small distance in this LDA space, effectively grouping similar playing styles together. In this sense we can use LDA as a classifier for player behaviour; not necessarily predicting the correct class i. Of course, the quality of this indication of playing style what is symbiosis give two examples on the quality of the linear discriminant analysis.

If the measured features are unsuitable for distinguishing player behaviour, or the game does not provide for enough expressivity, a good class separation will not be possible, thus creating a space that does not represent player behaviour and skill well. Figure 1. Each number represents a player, appearing five times as five games were recorded. Some players76,have been highlighted with circles. Each number represents a player, and will appear five times, its position marking the characteristics of one session of that player.

The figure suggests that according to the periodic law what is the relationship between elements and periods sessions of the players share similarities and the chosen features can be used to classify player behaviour. In the graph we can see groups of what is symbiosis give two examples five sessions from the same player clustered together, which indicates a similarity between these sessions a player behaviour trait has been identified.

The features used in our dataset are sufficient to reveal differences between players and similarities between games of the same player and we can therefore interpret the LDA space as an approximation to a space where the distance between sessions is determined by player behaviour and style. The analysis of the survey data indicates successful detection of player behaviour in game data recorded what is symbiosis give two examples a relatively simple computer game.

We have shown that linear discriminant analysis is a useful tool to process the data, reduce significant dimensions and identify important features, and will continue to use it as a first step in our player behaviour analysis. Of course, more analysis will be required to further quantify the correctness and usefulness of this approach and compare it to other methods such as principal component analysis and bayesian network classification.

In our data, we were able to determine that the most important gameplay features returned by our analysis are also what defines a game in general: physical interaction with the device, and secondly the main goals of the game. We discovered that players can easily be aligned along the dimensions of risk averse over risk accepting to risk seeking. In particular, in Pac-Man that meant that players tried to avoid ghosts, or had an efficient strategy to deal with them, or risked too much and lost lives early.

We have shown in the last section how AI can be implemented in computer games in order to improve them, but now we will be going in the opposite direction: How computer games can contribute to improve Artificial Intelligence, and more concretely, Computational Creativity. We argue that computer games can be used to improve AI systems, harnessing the human potential for the machine training process.
