Human Emotions Classification using Machine Learning Techniques

Human emotions have a long flourshing purpose for our survival as a species. They are either a response to an external stimulus, or a spontaneous expression of an internal thought process. Emotions like fear are often a reaction to an external stimulus, such as when we cross a busy road the fear of getting run-over causes our evolutionary survival mechanism to take effect.  These are external causes that activates the emotions inside our brain. However, emotions can be invoked as the result of an internal thought process. For example, If I managed to find a solution to a complicated mathematical differential equation, that could make me happy as a result of a feeling of personal satisfaction. This paper reviews the importance of emotion in day-to-day life and the emerging growth of emotion computer in AI, how a computer can show affections and how a computer creates intelligent agents that show emotions to other agents that communicate with them in the same environment.
