Artificial Intelligence (AI) is a discipline within computer science. In Germany, the synonym ‘Künstliche Intelligenz’ (KI) is also used.
AI deals with methods that enable machines (computers) to solve tasks in the same way that a human would using their intelligence.
Artificial Intelligence therefore encompasses not only aspects of information technology, but also those of psychology, neuroscience, linguistics, communication studies, mathematics and philosophy.
Computer science is therefore more of a means to an end. It brings the various disciplines together and enables their implementation.
In order for AI to solve tasks independently, it must be trained. To this end, experts use special algorithms and provide the AI with training data. Through continuous training, the AI improves steadily – until it can solve the tasks set for it on its own.
There are essentially two or three types of Artificial Intelligence:
1. Autonomous and automatic task completion (weak AI)
The most widely used form of AI today is ‘weak AI’, or weak artificial intelligence.
Solutions such as intelligent software assistants, internet search engines, self-driving cars and speech recognition systems already utilise AI. As a result, they are becoming an increasingly common part of our everyday lives.
Although such systems have already achieved an enormous level of performance, they are referred to in technical terminology as weak AI.
The reason for this is that weak AI solutions operate at a relatively superficial level of intelligence. They do not develop a deep understanding of problem-solving.
2. Mimicking human thought and behaviour (strong AI)
Strong AI aims to attain or surpass human intellectual capabilities.
Systems with strong AI can recognise patterns and learn. Above all, they can apply the knowledge they have acquired to many new tasks. This works even when these tasks are not covered by existing algorithms.
Strong AI acts actively and flexibly, on an equal footing with humans. However, systems with strong AI do not yet exist.
3. Artificial superintelligence
Systems with ‘artificial superintelligence’ theoretically possess consciousness and human characteristics such as emotions.
To date, it has not yet been possible to develop such superintelligence. There is heated debate amongst researchers as to whether the development of such AI is even feasible.
