Challenge #2
Make news real again!
Your challenge is to build a model which will make it easier and more efficient to identify what really is fake news and what is not (+ everything in between). You model should be able to determine a level of credibility, content authenticity, and limit the viral spread of fake content, including fake images.
Sample dataset: https://www.kaggle.com/mrisdal/fake-news
The dataset contains text and metadata from 244 websites [...] Each website was labeled according to the BS Detector [...] There are (ostensibly) no genuine, reliable, or trustworthy news sources represented in this dataset (so far), so don't trust anything you read.
Another example dataset: http://www.fakenewschallenge.org/
Stance Detection involves estimating the relative perspective (or stance) of two pieces of text relative to a topic, claim or issue. [...] we have chosen the task of estimating the stance of a body text from a news article relative to a headline. Specifically, the body text may agree, disagree, discuss or be unrelated to the headline.

Challenge #3
Emotional AI
Your challenge is to build a model (from scratch or on top of an existing model) that is smart enough to recognize various emotions through voice or facial expressions.
