Learning from user's behaviour of some well-known congested traffic networks
We consider the problem of predicting users' behavior of a congested traffic network under an equilibrium condition, the traffic assignment problem. We propose a two-stage machine learning approach which couples a neural network with a fixed point algorithm, and we evaluate its performance along several classical congested traffic networks.

5 - I went to Brooklyn’s #Book Festival last month and it was FULL.
So many people even at the very end of the day - people buying books, people walking around and sitting down in any spot they could find in the park to start reading what they got.
I heard multiple vendors talking to each other about how they didn’t bring enough stock to meet demand that day - in fact I couldn’t buy anything from multiple vendors I wanted to support because they had so few books left, and sold out of the ones I was interested in.
