So I want to build Artificial Emotional Intelligence (AEI), and I already wrote about a possible application to treat mental health problems. Even the big guns like Apple Inc. are trying to build AEI (for some obscure reason). So the obvious step when you want to build something is to study and to do research.
As much as I tried not to fall for the hype recently gained by Deep Learning, I could not really resist to explore their promises. Let me quickly explain. In order to build real AEI I wanted to start by the component that can understand our words. This belongs to the fields called Natural Language Processing (NLP), and Computational Linguistics (CL). Building powerful and useful NLP/CL systems is extremely challenging. It took me nearly 3 years to build a system that can guess your emotions from what you write, and the accuracy is far from perfect. The reason is that such systems are traditionally built using manually defined rules, features, and algorithms tailored for specific tasks.
