Emotion is a type of intelligence, and intelligence is multidimensional, and subjective as well.
Neuroscientists still discuss what emotions really are or what we can use as a suitable definition. They should not be regarded as mysterious or magical only, and the scientific approach will help understand emotions as a type of intelligence, which can be simulated at a certain way. A great deal of human cognition is influenced by emotions. In order to simulate this cognition in a computer, the goal of strong Artificial Intelligence, the influence that emotions have on cognition has to be taken into consideration.
What is emotion: It is a signal sent to Processing Unit (Brain) for some action done to our sensors (Body<Touch>, Nose<Smell>, Eye<Visual/Irritation> etc, so that Processing Unit (Brain) responds to that stimulus, how it responds are the decision made by Processing Unit internally and activating appropriate sensors through one of outputs. An 'emotion' is evidenced by behavior patterns. It is the pattern that is observable. The pattern can be simulated by a skilled actor/actress. In principle, it can be simulated by a machine; in practice, it’s a long way to go.
There are studies show that emotions play an important role in memory formation. We cannot remember everything and emotions help sort out what is important for us to remember. Some of these processes happen while we are sleeping and dreaming. Although emotion is complicated, you like to imagine that it's something super magical and mysterious, but you can discover some patterns in it, at least once you get the ability to have a single dimension or perspective in mind. For example, hunger can be described as the goal to replenish energy stores. Fear can be described as a goal which also allows one to override energy-expenditure constraints. Anger as the goal to defend. Love as the goal to nourish. Empathy is the ability to be aware of a second person perspective, current state and goals in addition to one's own current state and goals.
Emotions are just another category of intelligence. For example, targeting modeling empathy could be more useful: You could try training your AI to spot non-verbal communication. You could try implementing a user transactional analysis to try to help understand and respond appropriately to conversations. You could use simulation to consider alternative conversational responses and their possible effects on a target conversational outcome. To a certain degree, an AI will be able to deal with EI or EQ. Not just deal with it, it can even manipulate some emotions to achieve certain outcomes.
Emotion is a type of intelligence, and intelligence is multidimensional, and subjective as well: Mankind likes to say that a machine or agent is intelligent when they conclude that it acts intelligently and most of all similar to human’s 'intelligent' behaviour. Will machine have both high IQ and high EQ, it takes time to see.
