' ' Reactive machines: this is a simple model that seeks to reproduce human behavior through actions that react to stimuli. Their role is to respond, not to learn.' '
' Limited memory: these are also reactive machines but with some memory, which enables them to learn data and make small decisions. This type of AI is applied to facial recognition systems and chatbots, for instance.' '
' ' Theory of mind: this is one of the most innovative AI models; it seeks to understand higher-level interactions such as human emotions, needs, and inner reflections. It needs more research and is projected for the future.' '
' ' Self-awareness: though this is only a concept and there are no concrete creations of this type of AI, self-awareness suggests that machines might go beyond replicating human behavior and become able to think and act autonomously, gaining awareness of themselves.' '
