Opening question:
Do your facial movements broadcast your emotions to other people? If you think the answer is yes, think again.
A question that has been under contentious debate, with some experts maintain that people around the world make specific, recognizable faces that express certain emotions, such as smiling in happiness, scowling in anger and gasping with widened eyes in fear. They point to hundreds of studies and often cite Charles Darwin’s 1872 book "The Expression of the Emotions in Man and Animals".
Applications of machine and deep learning have shown quite interesting questions, with an increasing number of researchers urging for thinking more seriously and moving beyond the essentialist ideas of "detecting emotions".
Mistakes are part of the scientific process - and opportunities for discovery.
