Reactive machines can be employed for executing fundamental autonomous processes.

Despite their usefulness in certain applications, reactive machines have limitations. They don’t allow for learning or adaptation; they can only recognise and respond to a certain amount of data. Consequently their functionality is limited in comparison to those that have the ability to learn and improve. Moreover, they are unable to build upon previous knowledge or perform complex tasks that require learning and adaptation.

Limited Memory AI

Limited Memory AI systems, as the name suggests, utilise past data to make informed decisions and enhance their performance over time. By observing other vehicles’ speed and direction, self-driving cars can navigate the road and adjust accordingly. This kind of AI evolves over time as it is taught on more data, making it more advanced than reactive machines.

Limited Memory AI has found applications in various sophisticated use cases, such as chatbots, virtual assistants, and natural language processing. These systems demonstrate the potential of AI to learn from past experiences and improve their capabilities over time, offering more flexible and adaptable solutions compared to reactive machines.

Theory of Mind AI

Theory of Mind AI is an advanced category of AI systems that focus on comprehending and interpreting the human mind, including emotions, beliefs, and intentions. These systems are still under research and development, with the goal of enabling AI to better understand and interact with humans and other agents. For example, a self-driving car that is aware of a neighbor’s child playing near the street after school would naturally reduce speed when passing that neighbor’s driveway – something a basic limited memory AI would be unable to do.

Despite the potential benefits of Theory of Mind AI in various applications, there are concerns and challenges to consider. Emotional cues are highly complex, and it may take a significant amount of time for AI machines to master them, leading to potential errors during the learning stage.

Additionally, once technologies can detect and respond to emotional signals, it could result in the automation of certain occupations, raising ethical and societal questions.
