There has been a steep increase in the research in recent days on AI and related technologies/techniques. Another spike of trends in adoption of Neural Networks, now Deep Neural Networks. The recent launch of Allo by Google seems to be an outcome of that.
Allo is a any other chat app like whatsapp but an addition of Google (AI) Assistant which answers your questions, sets reminders for you, searches for places around you based on where u r located and much more. For some questions though which it does not have answers gives the top best google search result. It also comes with another feature of predicting a response to a chat message. But i personally find it a nice handy app to set a quick reminder or lets say, tell it to give me weather forecast every morning at 10 and it does it as commanded. ALLO!
